一.实验内容
Python综合应用:爬虫、数据处理、可视化、机器学习、神经网络、游戏、网络安全等。
二. 实验过程及结果
(一) 实验分析与设计
该游戏为打地鼠,通过鼠标点击地鼠记录分数,倒计时结束停止。
游戏中主要有两个对象:地鼠和锤子,创建enemies类和cursor类。锤子需要靠鼠标的移动来击打地鼠,通过尝试得出地鼠可能出现的位置坐标,再通过定义函数generate_next_pos()来生成地鼠出现的位置。并定义age_enemy()来设置地鼠存活的时间,再用remove_died_enemies()来移除死去的地鼠。当右上角的Time变成0后,不再画地鼠,实现游戏的结束,并且可以在左上角看到自己的得分。
(二) 实现过程
1.安装pygame
pygame是一组跨平台的python模块,用于创建视频游戏,现在已被用于数百种商业和开源游戏。
python -m pip install pygame
2.初步完成打地鼠的窗口
(1).创建并保持游戏窗口
导入pygame模块,调用init()方法初始化pygame模块。设置窗口的宽高,使用display模块显示窗体
import pygame pygame.init()#初始化窗体 screen = pygame.display.set_mode((1000, 800))
(2).设置分数和倒计时时间
让分数显示在左上角,时间在右上角。
1 import pygame 2 3 pygame.init()#初始化窗体 4 5 screen = pygame.display.set_mode((1000, 800)) 6 7 score_value = 0#设置分数 8 font = pygame.font.Font('freesansbold.ttf', 32) 9 10 count_now = 60#设置时间 11 font = pygame.font.Font('freesansbold.ttf',32) 12 13 textX = 10#设置分数位置 14 textY = 10 15 16 textx = 250#设置时间位置 17 texty = 10
(3).设定初步的模型
先将地鼠用黄色的圆代替,后期再修改。
1 import pygame 2 3 pygame.init()#初始化窗体 4 5 screen = pygame.display.set_mode((1000, 800)) 6 7 score_value = 0#设置分数 8 font = pygame.font.Font('freesansbold.ttf', 32) 9 10 count_now = 60#设置时间 11 font = pygame.font.Font('freesansbold.ttf',32) 12 13 textX = 10#设置分数位置 14 textY = 10 15 16 textx = 250#设置时间位置 17 texty = 10 18 19 enemies = [] 20 21 NUM_COL = 2#目标出现的位置 22 NUM_ROW = 2 23 24 ENEMY_RADIUS = 150#目标设定 25 ENEMY_COLOR = (255, 255, 0)
(4).随机生成地鼠及其可能出现的位置
1 import pygame 2 import math 3 import random 4 5 6 pygame.init()#初始化窗体 7 8 screen = pygame.display.set_mode((1000, 800)) 9 10 score_value = 0#设置分数 11 font = pygame.font.Font('freesansbold.ttf', 32) 12 13 count_now = 60#设置时间 14 font = pygame.font.Font('freesansbold.ttf',32) 15 16 textX = 10#设置分数位置 17 textY = 10 18 19 textx = 250#设置时间位置 20 texty = 10 21 22 enemies = [] 23 24 NUM_COL = 2#目标出现的位置 25 NUM_ROW = 2 26 27 ENEMY_RADIUS = 150#目标设定 28 ENEMY_COLOR = (255, 255, 0) 29 30 def get_pos_by_grid_ind(row, col):#随机生成地鼠及其可能出现的位置 31 return (200+row*400, 200+col*400) 32 33 def generate_next_enemy_pos(): 34 grid_index = random.randint(0, 3) 35 row = math.floor(grid_index/NUM_COL) 36 col = grid_index%NUM_COL 37 return get_pos_by_grid_ind(row, col)
(5).将地鼠在窗体中画出来和分数和时间在窗体中的显示
1 import pygame 2 import math 3 import random 4 5 6 pygame.init()#初始化窗体 7 8 screen = pygame.display.set_mode((1000, 800)) 9 10 score_value = 0#设置分数 11 font = pygame.font.Font('freesansbold.ttf', 32) 12 13 count_now = 60#设置时间 14 font = pygame.font.Font('freesansbold.ttf',32) 15 16 textX = 10#设置分数位置 17 textY = 10 18 19 textx = 250#设置时间位置 20 texty = 10 21 22 enemies = [] 23 24 NUM_COL = 2#目标出现的位置 25 NUM_ROW = 2 26 27 ENEMY_RADIUS = 150#目标设定 28 ENEMY_COLOR = (255, 255, 0) 29 30 def get_pos_by_grid_ind(row, col):#随机生成地鼠及其可能出现的位置 31 return (200+row*400, 200+col*400) 32 33 def generate_next_enemy_pos(): 34 grid_index = random.randint(0, 3) 35 row = math.floor(grid_index/NUM_COL) 36 col = grid_index%NUM_COL 37 return get_pos_by_grid_ind(row, col) 38 39 def draw_enemies():#画地鼠 40 for enemy in enemies: 41 pygame.draw.circle(screen, ENEMY_COLOR, (enemy[0], enemy[1]), ENEMY_RADIUS) 42 43 44 def show_score(x, y):#显示分数 45 global score_value 46 score = font.render("Score: "+str(score_value), True, (255, 255, 255)) 47 screen.blit(score, (x, y)) 48 49 def show_time(x,y):#显示时间 50 global time_value 51 time = font.render("Time: "+str(count_now), True, (255, 255, 255)) 52 screen.blit(time, (x, y)) 53
(6). 将开始运行后所有鼠标点击的位置发生的效果进行分析。
当点到×时游戏结束,当鼠标点击到地鼠身上时定义了一个函数,如果点到,分数加一,并且设置地鼠出现的时间。
1 import pygame 2 import math 3 import random 4 5 6 pygame.init()#初始化窗体 7 8 screen = pygame.display.set_mode((1000, 800)) 9 10 score_value = 0#设置分数 11 font = pygame.font.Font('freesansbold.ttf', 32) 12 13 count_now = 60#设置时间 14 font = pygame.font.Font('freesansbold.ttf',32) 15 16 textX = 10#设置分数位置 17 textY = 10 18 19 textx = 250#设置时间位置 20 texty = 10 21 22 enemies = [] 23 24 NUM_COL = 2#目标出现的位置 25 NUM_ROW = 2 26 27 ENEMY_RADIUS = 150#目标设定 28 ENEMY_COLOR = (255, 255, 0) 29 30 def get_pos_by_grid_ind(row, col):#随机生成地鼠及其可能出现的位置 31 return (200+row*400, 200+col*400) 32 33 def generate_next_enemy_pos(): 34 grid_index = random.randint(0, 3) 35 row = math.floor(grid_index/NUM_COL) 36 col = grid_index%NUM_COL 37 return get_pos_by_grid_ind(row, col) 38 39 def draw_enemies():#画地鼠 40 for enemy in enemies: 41 pygame.draw.circle(screen, ENEMY_COLOR, (enemy[0], enemy[1]), ENEMY_RADIUS) 42 43 44 def show_score(x, y):#显示分数 45 global score_value 46 score = font.render("Score: "+str(score_value), True, (255, 255, 255)) 47 screen.blit(score, (x, y)) 48 49 def show_time(x,y):#显示时间 50 global time_value 51 time = font.render("Time: "+str(count_now), True, (255, 255, 255)) 52 screen.blit(time, (x, y)) 53 54 def check_enemy_collision(clickX, clickY, enemyX, enemyY): 55 distance = math.sqrt(math.pow(enemyX-clickX, 2)+(math.pow(enemyY-clickY, 2))) 56 return distance<ENEMY_RADIUS 57 58 def check_enemies_collision(click_pos, enemies): 59 for enemy in enemies: 60 if check_enemy_collision(click_pos[0], click_pos[1], enemy[0], enemy[1]): 61 global score_value 62 score_value +=1 63 enemies.remove(enemy) 64 65 running = True 66 while running: 67 for event in pygame.get(): 68 if event.type == pygame.QUIT: 69 running = False 70 if event.type == pygame.MOUSEBUTTONUP: 71 click_pos = pygame.mouse.get_pos() 72 check_enemies_collision(click_pos, enemies) 73 74 if pygame.time.get_ticks() % 3000 < 10 75 enemies.append(generate_next_enemy_pos())
(7).最后将运行时该出现的要素都写进来。
1 import pygame 2 import math 3 import random 4 5 6 pygame.init()#初始化窗体 7 8 screen = pygame.display.set_mode((1000, 800)) 9 10 score_value = 0#设置分数 11 font = pygame.font.Font('freesansbold.ttf', 32) 12 13 count_now = 60#设置时间 14 font = pygame.font.Font('freesansbold.ttf',32) 15 16 textX = 10#设置分数位置 17 textY = 10 18 19 textx = 250#设置时间位置 20 texty = 10 21 22 enemies = [] 23 24 NUM_COL = 2#目标出现的位置 25 NUM_ROW = 2 26 27 ENEMY_RADIUS = 150#目标设定 28 ENEMY_COLOR = (255, 255, 0) 29 30 def get_pos_by_grid_ind(row, col):#随机生成地鼠及其可能出现的位置 31 return (200+row*400, 200+col*400) 32 33 def generate_next_enemy_pos(): 34 grid_index = random.randint(0, 3) 35 row = math.floor(grid_index/NUM_COL) 36 col = grid_index%NUM_COL 37 return get_pos_by_grid_ind(row, col) 38 39 def draw_enemies():#画地鼠 40 for enemy in enemies: 41 pygame.draw.circle(screen, ENEMY_COLOR, (enemy[0], enemy[1]), ENEMY_RADIUS) 42 43 44 def show_score(x, y):#显示分数 45 global score_value 46 score = font.render("Score: "+str(score_value), True, (255, 255, 255)) 47 screen.blit(score, (x, y)) 48 49 def show_time(x,y):#显示时间 50 global time_value 51 time = font.render("Time: "+str(count_now), True, (255, 255, 255)) 52 screen.blit(time, (x, y)) 53 54 def check_enemy_collision(clickX, clickY, enemyX, enemyY): 55 distance = math.sqrt(math.pow(enemyX-clickX, 2)+(math.pow(enemyY-clickY, 2))) 56 return distance<ENEMY_RADIUS 57 58 def check_enemies_collision(click_pos, enemies): 59 for enemy in enemies: 60 if check_enemy_collision(click_pos[0], click_pos[1], enemy[0], enemy[1]): 61 global score_value 62 score_value +=1 63 enemies.remove(enemy) 64 65 running = True 66 while running: 67 for event in pygame.event.get(): 68 if event.type == pygame.QUIT: 69 running = False 70 if event.type == pygame.MOUSEBUTTONUP: 71 click_pos = pygame.mouse.get_pos() 72 check_enemies_collision(click_pos, enemies) 73 74 if pygame.time.get_ticks() % 3000 < 5: 75 enemies.append(generate_next_enemy_pos()) 76 77 screen.fill((0, 0, 0))#画背景 78 draw_enemies()#画地鼠 79 show_score(textX,textY)#显示分数 80 show_time(textx,texty)#显示时间 81 pygame.display.update()#更新界面
完成后的效果图如下
3.进一步完善这个模型
(1).将这个黑色的背景换成地鼠洞
利用pygame.image.load()将背景图片导入。
import pygame import math import random pygame.init()#初始化窗体 bg_image = pygame.image.load("0.png")#设置游戏界面 #bg_image = pygame.transform.scale(bg_image, (bg_image.get_width()/3, bg_image.get_height()/3)) screen = pygame.display.set_mode((bg_image.get_width(), bg_image.get_height())) score_value = 0#设置分数 font = pygame.font.Font('freesansbold.ttf', 32) ... screen.blit(bg_image, (0, 0))#填充游戏背景 draw_enemies()#画地鼠 show_score(textX,textY)#显示分数 show_time(textx,texty)#显示时间 pygame.display.update()#更新界面
(2).将原来的黄圈改成地鼠
首先根据地鼠的坑位将原来的2*2改成5*5,再通过试的方法将地鼠的坑位和地鼠出现的坐标保持一致,同时用pygame.image.load()将地鼠的图片导入,最后再根据现在地鼠的位置将原来算好的地鼠出现的位置的函数 check_exist(new_pos)和generate_next_enemy_pos()改正
import pygame ... NUM_COL = 5#设置地鼠出现的位置 NUM_ROW = 5 possible_enemy_pos = [(5,52),(170,52),(85,52),(250,52),(330,52),(5,125),(85,125),(170,125),(250,125),(330,125), (5,198),(85,198),(170,198),(250,198),(330,198),(5,270),(85,270),(170,270),(250,270),(330,270), (5,345),(85,345),(170,345),(250,345),(330,345)]#设置地鼠的具体位置 enemy_image = pygame.image.load("3.jpg")#导入地鼠图片 #enemy_image = pygame.transform.scale(enemy_image, (enemy_image.get_width() // 2,enemy_image.get_height() // 2)) ENEMY_RADIUS = min(enemy_image.get_width(), enemy_image.get_height())// 2.5 #enemybeated_image = pygame.image.load("4.jpg") def check_exist(new_pos): for enemy in enemies: if new_pos == (enemy.x, enemy.y): return True return False def generate_next_enemy_pos():#算出地鼠出现的位置 new_pos=() while True: grid_index = random.randint(0, NUM_ROW*NUM_COL-1) new_pos = possible_enemy_pos[grid_index] if not check_exist(new_pos): break return new_pos def draw_enemies():#画地鼠 for enemy in enemies: screen.blit(enemy_image, (enemy.x, enemy.y)) ...
(3).修改鼠标点击判断
此时运行代码发现点地鼠没有反应,是因为判断鼠标点击位置和地鼠出现的位置出现偏差。
import pygame ... def check_enemy_collision(clickX, clickY, enemyX, enemyY):#检查鼠标和点击的位置相不相同 enemyX,enemyY = enemyX + ENEMY_RADIUS, enemyY+ENEMY_RADIUS distance = math.sqrt(math.pow(enemyX - clickX,2)+(math.pow(enemyY-clickY,2))) return distance<ENEMY_RADIUS ...
(4).修改地鼠出现的时间
pygame对于这些地鼠出现的时间有规范的写法,可以进行规范化。
import pygame ... enemy_image = pygame.image.load("3.jpg")#导入地鼠图片 #enemy_image = pygame.transform.scale(enemy_image, (enemy_image.get_width() // 2,enemy_image.get_height() // 2)) ENEMY_RADIUS = min(enemy_image.get_width(), enemy_image.get_height())// 2.5 enemybeated_image = pygame.image.load("4.jpg") GENERATE_ENEMY, APPEAR_INTERVAL = pygame.USEREVENT + 2, 500 pygame.time.set_timer(GENERATE_ENEMY, APPEAR_INTERVAL) ... running = True#鼠标点击时发生的事情(关闭键和点地鼠 while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False if event.type == pygame.MOUSEBUTTONUP: click_pos = pygame.mouse.get_pos() check_enemies_collision(click_pos, enemies) if event.type == GENERATE_ENEMY: if len(enemies) < NUM_COL*NUM_ROW: new_pos = generate_next_enemy_pos() enemies.append(Enemy(new_pos[0], new_pos[1])) ...
(5).给地鼠赋予生命
当一段时间没有打到这个地鼠,它就会自己钻回洞里。
import pygame import random import math import sys from dataclasses import dataclass ... GENERATE_ENEMY, APPEAR_INTERVAL = pygame.USEREVENT + 2, 500 pygame.time.set_timer(GENERATE_ENEMY, APPEAR_INTERVAL) ENEMY_LIFE_SPAN = 3*1000 AGE_ENEMY, AGE_INTERVAL = pygame.USEREVENT+2, ENEMY_LIFE_SPAN//7 pygame.time.set_timer(AGE_ENEMY, AGE_INTERVAL) @dataclass class Enemy: x: int y: int life: int = ENEMY_LIFE_SPAN ... def age_enemy(): for enemy in enemies: enemy.life -= 1000 def remove_died_enemies(): for enemy in enemies: if enemy.life == 0: enemies.remove(enemy) running = True#鼠标点击时发生的事情(关闭键和点地鼠 while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False if event.type == pygame.MOUSEBUTTONUP: click_pos = pygame.mouse.get_pos() check_enemies_collision(click_pos, enemies) if event.type == AGE_ENEMY: age_enemy() remove_died_enemies() if event.type == GENERATE_ENEMY: if len(enemies) < NUM_COL*NUM_ROW: new_pos = generate_next_enemy_pos() enemies.append(Enemy(new_pos[0], new_pos[1])) ...
(6).鼠标改成锤子
现在我们要将游戏界面中的鼠标改成锤子。注意,要将显示锤子的代码写在背景和地鼠之后,防止被遮挡。
import pygame ... def remove_died_enemies(): for enemy in enemies: if enemy.life == 0: enemies.remove(enemy) cursor_image = pygame.image.load("1.png") # 设置鼠标图片 pygame.mouse.set_visible(False) # 隐藏鼠标 ... screen.blit(bg_image, (0, 0))#填充游戏背景 if count_now != 0: draw_enemies()#显示地鼠 show_score(textX, textY)#显示分数 show_time(textx, texty) pointer_rect = cursor_image.get_rect() pointer_rect.center = pygame.mouse.get_pos() cursor_x = pointer_rect.x cursor_y = pointer_rect.y screen.blit(cursor_image, (cursor_x+20, cursor_y)) pygame.display.update()#更新游戏界面
(7).将倒计时进行下去
运行代码后发现倒计时始终没有变,是因为还没有加入倒计时的代码。
import pygame ... ENEMY_LIFE_SPAN = 3*1000 AGE_ENEMY, AGE_INTERVAL = pygame.USEREVENT+2, ENEMY_LIFE_SPAN//7 pygame.time.set_timer(AGE_ENEMY, AGE_INTERVAL) clock_event = pygame.USEREVENT+3 pygame.time.set_timer(clock_event,1000) ... running = True#鼠标点击时发生的事情(关闭键和点地鼠 while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False if event.type == pygame.MOUSEBUTTONUP: click_pos = pygame.mouse.get_pos() check_enemies_collision(click_pos, enemies) if event.type == AGE_ENEMY: age_enemy() remove_died_enemies() if event.type == GENERATE_ENEMY: if len(enemies) < NUM_COL*NUM_ROW: new_pos = generate_next_enemy_pos() enemies.append(Enemy(new_pos[0], new_pos[1])) if event.type == clock_event: count_now-= 1 font.render("Time:"+str(count_now), True, (255, 255, 255)) if count_now == 0: pygame.time.set_timer(clock_event, 0) ...
(三) 实验结果
最终代码
import pygame import random import math import sys from dataclasses import dataclass pygame.init()#游戏初始化 bg_image = pygame.image.load("0.png")#设置游戏界面 bg_image = pygame.transform.scale(bg_image, (bg_image.get_width()/3, bg_image.get_height()/3)) screen = pygame.display.set_mode((bg_image.get_width(), bg_image.get_height())) score_value = 0#设置分数 font = pygame.font.Font('freesansbold.ttf',32) count_now = 60 font = pygame.font.Font('freesansbold.ttf',32) textX = 10#分数位置 textY = 10 textx = 250 texty = 10 count = 0 enemies = []#设置地鼠 NUM_COL = 5#设置地鼠出现的位置 NUM_ROW = 5 possible_enemy_pos = [(5,50),(170,50),(85,50),(250,50),(330,50),(5,125),(85,125),(170,125),(250,125),(330,125), (5,198),(85,198),(170,198),(250,198),(330,198),(5,270),(85,270),(170,270),(250,270),(330,270), (5,345),(85,345),(170,345),(250,345),(330,345)]#设置地鼠的具体位置 enemy_image = pygame.image.load("3.jpg")#导入地鼠图片 #enemy_image = pygame.transform.scale(enemy_image, (enemy_image.get_width() // 2,enemy_image.get_height() // 2)) ENEMY_RADIUS = min(enemy_image.get_width(), enemy_image.get_height())// 2.5 enemybeated_image = pygame.image.load("4.jpg") GENERATE_ENEMY, APPEAR_INTERVAL = pygame.USEREVENT + 2, 500 pygame.time.set_timer(GENERATE_ENEMY, APPEAR_INTERVAL) ENEMY_LIFE_SPAN = 3*1000 AGE_ENEMY, AGE_INTERVAL = pygame.USEREVENT+2, ENEMY_LIFE_SPAN//7 pygame.time.set_timer(AGE_ENEMY, AGE_INTERVAL) clock_event = pygame.USEREVENT+3 pygame.time.set_timer(clock_event,1000) @dataclass class Enemy: x: int y: int life: int = ENEMY_LIFE_SPAN def check_exist(new_pos): for enemy in enemies: if new_pos == (enemy.x, enemy.y): return True return False def generate_next_enemy_pos():#算出地鼠出现的位置 new_pos=() while True: grid_index = random.randint(0, NUM_ROW*NUM_COL-1) new_pos = possible_enemy_pos[grid_index] if not check_exist(new_pos): break return new_pos def draw_enemies():#画地鼠 for enemy in enemies: screen.blit(enemy_image, (enemy.x, enemy.y)) def show_score(x,y):#显示分数 global score_value score = font.render("Score: "+str(score_value), True, (255, 255, 255)) screen.blit(score, (x, y)) def show_time(x,y): global time_value time = font.render("Time: "+str(count_now), True, (255, 255, 255)) screen.blit(time, (x, y)) def check_enemy_collision(clickX, clickY, enemyX, enemyY):#检查鼠标和点击的位置相不相同 enemyX,enemyY = enemyX + ENEMY_RADIUS, enemyY+ENEMY_RADIUS distance = math.sqrt(math.pow(enemyX - clickX,2)+(math.pow(enemyY-clickY,2))) return distance<ENEMY_RADIUS def check_enemies_collision(click_pos, enemies):#检测鼠标点击的位置和地鼠的位置相不相同,并移除地鼠 for enemy in enemies: if check_enemy_collision(click_pos[0], click_pos[1], enemy.x, enemy.y): global score_value score_value +=1 enemies.remove(enemy) #def appear_beated_enemy(): # for enemy in enemies: # if check_enemy_collision(click_pos[0], click_pos[1], enemy.x, enemy.y): # screen.blit(enemybeated_image, (enemy.x, enemy.y)) # if pygame.time.get_ticks() %3000 < 1: # enemies.remove(enemy) def age_enemy(): for enemy in enemies: enemy.life -= 1000 def remove_died_enemies(): for enemy in enemies: if enemy.life == 0: enemies.remove(enemy) cursor_image = pygame.image.load("1.png") # 设置鼠标图片 pygame.mouse.set_visible(False) # 隐藏鼠标 running = True#鼠标点击时发生的事情(关闭键和点地鼠 while running: for event in pygame.event.get(): if event.type == pygame.QUIT: running = False if event.type == pygame.MOUSEBUTTONUP: click_pos = pygame.mouse.get_pos() check_enemies_collision(click_pos, enemies) if event.type == AGE_ENEMY: age_enemy() remove_died_enemies() if event.type == GENERATE_ENEMY: if len(enemies) < NUM_COL*NUM_ROW: new_pos = generate_next_enemy_pos() enemies.append(Enemy(new_pos[0], new_pos[1])) if event.type == clock_event: count_now-= 1 font.render("Time:"+str(count_now), True, (255, 255, 255)) if count_now == 0: pygame.time.set_timer(clock_event, 0) screen.blit(bg_image, (0, 0))#填充游戏背景 if count_now != 0: draw_enemies()#显示地鼠 show_score(textX, textY)#显示分数 show_time(textx, texty) pointer_rect = cursor_image.get_rect() pointer_rect.center = pygame.mouse.get_pos() cursor_x = pointer_rect.x cursor_y = pointer_rect.y screen.blit(cursor_image, (cursor_x+20, cursor_y)) pygame.display.update()#更新游戏界面
(四) 将代码上传到华为云上
1.在华为云服务器上下载pygame
2.打开WinSCP,并将写好的文件和图片移到云服务器中
3.打开putty,登录华为为云服务器,并将环境设置好
4.由于游戏需要界面显示,因此要下载Xming
链接为https://pan.baidu.com/s/1wMDA-8zqd8eiu6iGWGPqFQ?_at_=1653577595955
5.进入先前python文件和图片保存的地址
6.打开先前下载的XLaunch,一直点击下一步完成
7.输入命令xterm,如果没有要另行下载
8.进入Xming后,输入python3 5.py便能在云端运行
三. 课程感想与意见建议
python课还是很有意思的,内容由浅入深,十分的丰富。由于有一点点其它语言的基础对于python最初的运用来时比较顺手的,又掌握了一门语言的基础中的基础的运用,开心。早就听说python语言简介明了不需要繁杂的定义也没有那么多的格式要求(除了缩进),在课程的不断学习中也是逐渐体会到了,也希望在日后的生活中能够继续学习python,更加深入的了解python
经过这一学期学习,我掌握了Python的语言基础、流程控制语句、序列的应用、有关字符串的操作、文件操作、异常处理,学习了解了正则表达式、网络爬虫、Socket编程、Python操作数据库等等。这门课程令人受益匪浅。
同时,我还在原先的认知水平上又了解到了Git,CSDN两个平台,尤其是CSDN网站对小白很友好,不会可以在上面提问,一些热心的人会为你解答,对于未来的学习大有帮助(只是这里面如果解答的人解释不清楚不能追问)。其中令我感触最深的就是Python的第三方库的数量之多、覆盖面之广,利用这些第三方库可以轻松实现许多复杂的功能,对于深入学习和创新实践大有裨益。
虽然课程结束了,但对Python的学习仍要继续、仍在路上。以后,我会继续坚持学习python!!
