python 文件操作

1、基本文件格式

import sys

def start():
    print(__file__)
    
if __name__ == "__main__":
    argvList = sys.argv
    start()

 

2、文件操作

import os #文件操作引用

#创建或覆盖文件
with open(os.path.dirname(__file__)+'\\1.txt',"w") as fw:            
    fw.write(f.read())    

#读取文件
with open(os.path.dirname(__file__)+'\\files\\1.txt') as f:
    print(f.read())

#获取文件夹列表，并循环输出
for path in os.listdir(os.path.dirname(__file__)+'\\files'):
        print(path);

# -*- coding:utf-8 -*-
import sys
import os

def start():
    #读取配置文件
    print(__file__) 
    print(os.listdir(os.path.dirname(__file__)+'\\files'));
    with open(os.path.dirname(__file__)+'\\1.txt',"w") as fw:    
        for path in os.listdir(os.path.dirname(__file__)+'\\files'):
            with open(os.path.dirname(__file__)+'\\files\\'+ path) as f:  
                fw.write(f.read())
                fw.write('\n')
                
    #os.system('pause')
                           
    
if __name__ == "__main__":
    argvList = sys.argv
    start()
