python文件名和文件路径操作实例

import os'''获得当前路径'''cwd=os.getcwd()print(cwd)

'''得到当前文件夹下的所有文件和文件夹'''print(os.listdir())

'''delete file'''os.remove('sw724.vaps')print(os.listdir())

'''删除单个目录和多个目录'''os.removedir()os.removedir()

'''检查是否是文件／文件夹'''print(os.path.isfile('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps'))print(os.path.isdir('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps'))

'''检查文件路径是否存在'''print(os.path.exists('/Users/liuxiaolong/PycharmProjects/untitled/iiii'))

'''分离文件名分离扩展名'''[dirname,filename]=os.path.split('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps')print(dirname,"/n",filename)[fname,fename]=os.path.splitext('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps')print(fname,"/n",fename)

'''获得文件路径获得文件名获得当前环境'''print("get pathname:",os.path.dirname('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps'))print("get filename:",os.path.basename('/Users/liuxiaolong/PycharmProjects/untitled/sw724.vaps'))print(os.getenv)
