[py2rb] re.finditer

はじめに

移植やってます

re.finditer (Python)

import re

text = "He was carefully disguised but captured quickly by police."
for m in re.finditer(r"\w+ly", text):
    print('%02d-%02d: %s' % (m.start(), m.end(), m.group(0)))

# 07-16: carefully
# 40-47: quickly

公式ドキュメントより、こちらの記事のほうが分かりやすい。

scan (Ruby)

text = "He was carefully disguised but captured quickly by police."

puts text.scan(/\w+ly/).map{ "#{text.index(_1).to_s.rjust(2, '0')}-#{(text.index(_1) + _1.size).to_s.rjust(2, '0')}: #{_1}" }

# 07-16: carefully
# 40-47: quickly

String#scan+String#indexで行けそう。

メモ

• Python の re.finditer を学習した
• 道のりは遠そう
