Python文件与文件夹操作

import os
import shutil

if __name__ == '__main__':
    print(os.path.abspath('.'))

    print(os.path.split('D:\\PyPro\\app\\h.py'))
    print(os.path.splitext('D:\\PyPro\\app\\h.py'))

    if not os.path.exists('D:\\PyPro\\app\\newdir') :
        os.mkdir(os.path.join('D:\\PyPro\\app', 'newdir'))
        print('mkdir success')
    else:
        print('the dir has existed')

    if os.path.exists('D:\\PyPro\\ss.txt') :
        print('the file is existed')
        shutil.copyfile('..\\ss.txt', 'D:\\PyPro\\app\\ss.txt')
    else:
        print('the file is not existed')

    if os.path.exists('D:\\PyPro\\copydir') & (not os.path.exists('D:\\PyPro\\app\\copydir')):
        print('copy dir')
        shutil.copytree('..\\copydir\\', 'D:\\PyPro\\app\\copydir')
    else:
        print('Didn\'t copy dir')
#   D:\PyPro\app 查看当前目录的绝对路径
#   ('D:\\PyPro\\app', 'h.py')
#   ('D:\\PyPro\\app\\h', '.py')
#   the dir has existed    新建文件夹
#   the file is existed    复制文件
#   the dir is existed    复制文件夹
当目标文件夹已存在时,无法复制文件夹,故要加上&后面的那个判断条件。而在复制文件时如果目标文件存在,则会直接覆盖上去,故不需要加第二个判断条件。
