はじめに

移植やってます。

raw文字列 (Python)

r = r'R'
print(type(r))
print(r)
print(r == 'R')

<class 'str'>
R   
True

pythonの正規表現でよくr''って出てきますが、単なるストリングでした。

inspecct (Ruby)

r = /R/
puts r.class
puts r
puts r == 'R'

puts r.inspect
puts r.inspect.class
puts r.inspect.gsub(/\//, '') == 'R'

Regexp
(?-mix:R)
false

/R/
String
true

Ruby/で囲まれた文字列はRegexpクラスですので、文字列と比較する場合変換する必要があります。

もしくは、いったん文字列で保管しておいて正規表現で使用する際にインスタンス化するかですね。
