Pythonで正規表現を確認したいときのスニペット

Last updated at Posted at 2022-06-28

ちょっと確認したい時に使うスニペット

import re

text = 'hoge'
pattern = '.g.'
result = re.sub(pattern, 'bar', text)

print(result)

備忘録

  • 置換時にマッチした文字を使いたい場合、$1,$2...ではなく\\1,\\2...とする
text = 'hoge'
pattern = 'h.(g.)'
result = re.sub(pattern, '\\1', text)
