本文主要是介绍python 文件处理,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!
目录读取
import os path = 'D:/01 计划&实施/' file_names = os.listdir( path ) for i in file_names: code = i.replace(".png","") str = "update talbe1 set seal_image='#"+i+"' where seal_code='"+code+"';" print(str)
文件读取
方式1 全部读取
# -*- coding: utf-8 -*- path = 'H:/xx.txt' str = "" f=open( path ,'r',encoding='utf-8') for line in f.readlines(): line = line.replace("\n"," ") str += line f.close() print(str)
方式2 逐行读取
# -*- coding: utf-8 -*- path = 'H:/xxx.txt' str = "" with open(path,'r',encoding='utf-8') as f: str = f.readlines() print(str)
