学习python第n天——我在看笨办法学python(这是所有的输入和输出了)

本文主要是介绍学习python第n天——我在看笨办法学python(这是所有的输入和输出了)，对大家解决编程问题具有一定的参考价值，需要的程序猿们随着小编来一起学习吧！

这是所有的语言

#以上都是输出的内容，下面会做一些输入

print("要记得单位是cm哦！")
print("这里只能输入一个小数。")
height = int(float(input()))#这里输入的是一个小数，可以加一个if语句。

print("How much do you weight?", end=' ')
print("要记得单位是kg哦！")
print("这里只能输入一个小数。")
weight = int(float(input()))
#int()给输入的数字取整。float表示输入的是一个小数。

print(f"So,you are {age} years old, {height} cm tall and {weight} kg heavy.")

#下面是另一种写法。
age1 = input("How old are you?")
height1 = int(float(input("\nHow tall are you?\n要记得单位是cm哦！\n这里只能输入一个小数。")))
weight1 = int(float(input("\nHow much do you weight?\n要记得单位是kg哦！\n这里只能输入一个小数。")))
print(f"So,you are {age1} years old, {height1} cm tall and {weight1} kg heavy.")
# python -m pydoc -w ex1这个可以输出一个exe文件，和一个html文件(可以按A-Z整理出所有的变量)

这是所有的运行结果

Hello world!
Hello again
I like typing this.
This is fun.
Yay!Printing.
I'd much rather you 'not'.
I "said" do not touch this.
now I will count my chickens.

Roosters 100
now I will count my eggs.

IS it ture that 3 + 2 < 5 - 7 ?
False
oh,that's why it's false.
what is 3 + 2? 5
what is 5 - 7? -2

Let's talk about Zed A. Shaw.
He is 35 years old.
He is 53 kg heavy.
He is 24.0403919 pound heavy.
He is 24.0403919 pound heavy.
Actually , it's not too heavy.
There are 10 types of people.
Those who know binary and those who don't .
I said :There are 10 types of people.
I also said :' Those who know binary and those who don't .'
Isn't the joke so funny? False!
This is the left side of...a string with a right side.
Mary had a little lamb.
It's fleece was wite as snow.
And everywhere that Mary went.

There's something going on here.
With the three double-quotes.
We will be able to type as much as we like.
Even 4 lines if we whant , or 5, or 6.

I'm tabbed in.
I'm split
on a line.
I'm \a\cat.

I'll do a list:
* cat food
* Fishies
* Catnip
* Grass

How old are you? 21
How tall are you? 要记得单位是cm哦！
这里只能输入一个小数。
163.3
How much do you weight? 要记得单位是kg哦！
这里只能输入一个小数。
53.3
So,you are 21 years old, 163 cm tall and 53 kg heavy.
How old are you?21

How tall are you?
要记得单位是cm哦！
这里只能输入一个小数。163.7

How much do you weight?
要记得单位是kg哦！
这里只能输入一个小数。53.7
So,you are 21 years old, 163 cm tall and 53 kg heavy.
