Python-如何在不更改其結構的情況下刪除復雜文件夾中的內容？

Question

我有一個帶有子文件夾的文件夾，每個文件夾可以包含更多子文件夾，依此類推。 我想刪除所有文件中的所有文件，但保持目錄結構不變。 是否有內置命令，或者我必須使用os.listdir為此編寫一些遞歸函數？

Answer 1

從Python文檔文件和目錄中無恥地偷了東西，並刪除了目錄：

# Delete everything reachable from the directory named in "top",
# assuming there are no symbolic links.
# CAUTION:  This is dangerous!  For example, if top == '/', it
# could delete all your disk files.
import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in files:
        os.remove(os.path.join(root, name))

Answer 2

參見os.walk ：

import os
top = '/some/dir'
for root, dirs, files in os.walk(top):
    for name in files:
        os.remove(os.path.join(root, name))

Answer 3

import os

#check if file is hidden 
def is_hidden(filepath):
    name = os.path.basename(os.path.abspath(filepath))
    return name.startswith('.')

top = '/dir'
for root, dirs, files in os.walk(top):
    for name in files:
       #do not delete hidden files (as asked by OP in comments)
       if is_hidden(name) == false:  
          os.remove(os.path.join(root, name))
