Python函数使任意字符串成为有效的文件名 [英] Python function to make arbitrary strings valid filenames

问题描述

是否有内置功能可以从字符串中删除Windows文件名中不能出现的所有字符或以某种方式替换它们?

Is there a built-in function which strips all characters which cannot be in Windows filenames from a string or replaces them somehow?

例如function("Some:unicode\symbols")-> "Some-unicode-symbols"

推荐答案

import re

arbitrary_string = "File!name?.txt"
cleaned_up_filename = re.sub(r'[/\\:*?"<>|]', '', arbitrary_string)
filepath = os.path.join("/tmp", cleaned_up_filename)

with open(filepath, 'wb') as f:
    # ...
