はじめに

移植やってます

repr() str() (Python)

>>> import datetime
>>> td = datetime.date.today()
>>> print(str(td))
2021-12-09
>>> print(repr(td))
datetime.date(2021, 12, 9)

内容はよく分かりませんが、Rubyだと次の感じかも。

inspect to_s (Ruby)

> require 'date'
> td = Date.today
> puts td.to_s
2021-12-09
> puts td.inspect
#<Date: 2021-12-09 ((2459558j,0s,0n),+0s,2299161j)>

上記の場合、.to_sは付けても付けなくても同じ結果になります。

メモ

  • Python の repr を学習した
  • 道のりは遠そう
