Python中os.walk函数的用法（遍历文件夹下文件并获得路径）

用法举例

• topdown 为真，则优先遍历top目录，否则优先遍历top的子目录(默认为开启)。

 

import os
for root, dirs, files in os.walk(".", topdown=True):
    for name in files:
        print(os.path.join(root, name))
    for name in dirs:
        print(os.path.join(root, name))
'''
.\api.csv
.\Untitled.ipynb
.\.ipynb_checkpoints
.\.ipynb_checkpoints\Untitled-checkpoint.ipynb
'''
'''
topdown为False的情况
.\.ipynb_checkpoints\Untitled-checkpoint.ipynb
.\api.csv
.\Untitled.ipynb
.\.ipynb_checkpoints
