Most efficient way to strip forbidden characters in file name from Unicode string [duplicate]

Question

I have a string which contain some data I parse from the web, and make a file named after this data.

string = urllib.urlopen("http://example.com").read()
f = open(path + "/" + string + ".txt")
f.write("abcdefg")
f.close()

The problem is that it may include one of this characters: \ / * ? : " < > |. I'm using Windows, and it is forbidden to use those characters in a filename. Also, string is in Unicode formar which makes most of the solutions useless.

So, my question is: what is the most efficient / pythonic way to strip those characters? Thanks in advance!

Edit: the filename is in Unicode format not str!

Answer 1

we dont know how your data look like:

But you can use re.sub:

import re
your_string = re.sub(r'[\\/*?:"<>|]',"","your_string")
