[py2rb] !r

はじめに

移植やってます。
( from python 3.7 to ruby 2.7 )

!r (Python)

>>> name = "Fred"
>>> f"He said his name is {name!r}."
"He said his name is 'Fred'."
>>> f"He said his name is {repr(name)}."  # repr() is equivalent to !r
"He said his name is 'Fred'."

'!r' は repr() を呼び出します。

どうする (Ruby)

name = "Fred"
puts "He said his name is #{__repr__(name)}."
# or
puts "He said his name is #{name.inspect}."
