ファイル名として無効な文字を削除(Python)

Posted at

Webスクレイピングでデータ取得していたときに、エラーが発生したのでメモ
Windowsではファイル名として無効文字\/:*?"<>|があるのでそれを削除する

re.sub(pattern, repl, string)

文字列置換にはreplace()があるが、正規表現で処理できないのでre.sub()を用いる
使い方は、re.sub('置換対象文字','置換文字','入力文字列')

re.sub
import re
string='\gbahsd:njs?<>|"asd/as*'

print(re.sub(r'[\\/:*?"<>|]+','',string)
output
'gbahsdnjsasdas'

以上
