pythonでregex matchしたとこをハイライトさせる場合のサンプルコード(どっかからのコピペだった…はず)

a.py

#!/usr/bin/env python3
# -*- encoding: UTF-8 -*-

import re
colourFormat = '\033[{0}m'
colourStr = colourFormat.format(32)
resetStr = colourFormat.format(0)
s = "This is a sentence where I talk about interesting stuff like sencha tea."

lastMatch = 0
formattedText = ''
for match in re.finditer(r'sen\w+', s):
    start, end = match.span()
    formattedText += s[lastMatch: start]
    formattedText += colourStr
    formattedText += s[start: end]
    formattedText += resetStr
    lastMatch = end
formattedText += s[lastMatch:]

print(formattedText)
