Python-如何在不更改其结构的情况下删除复杂文件夹中的内容？

Question

我有一个带有子文件夹的文件夹，每个文件夹可以包含更多子文件夹，依此类推。 我想删除所有文件中的所有文件，但保持目录结构不变。 是否有内置命令，或者我必须使用os.listdir为此编写一些递归函数？

Answer 1

从Python文档文件和目录中无耻地偷了东西，并删除了目录：

# 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

参见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))
