2021-08-26 Python之文件的复制

#文件的复制
'''
原文件：c:\pl\girl.jpg
目标文件：c:\p2\girl.jpg
'''

#with 结合open使用，可以帮助我们自动释放资源

with stream=open(r'c:\pl\girl.jpg','rb') as srteam:
    container=stream.read() #读取文件内容

    with open(r'c:\p2\girl.jpg','wb') as wstream:
        wstream.write(container)
print('文件复制完成')

#模块：os.py
'''
os.path:
os.path.dirname(__file__) 获取当前文件所在的目录
os.path.join(path,'') 返回的是一个拼接后的新路径
'''

import random
import os
print(os.path)
path=os.path.dirname(__file__)  #获取当前文件所在的目录（绝对路径）
print(path)
print(type(path))
result=os.path.join(path,'a1.jpg')  #在原来的文件夹下拼接一个文件的名字
print(result)


with open(r'c:\pl\girl.jpg','rb') as srteam:
    container=stream.read() #读取文件内容
    path=os.path.dirname(__file__)
    path1=os.path.join(path,'a1.jpg') 

    with open(path1,'wb') as wstream:
        wstream.write(container)

 

#复制文件夹
import os

#文件复制

target_path=r'c:\p2'

#封装成函数
