はじめに

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

予約語 (Python)

import keyword
print(keyword.kwlist)

['False', 'None', 'True', 'and', 'as', 'assert', 'async',
 'await', 'break', 'class', 'continue', 'def', 'del',
 'elif', 'else', 'except', 'finally', 'for', 'from',
 'global', 'if', 'import', 'in', 'is', 'lambda',
 'nonlocal', 'not', 'or', 'pass', 'raise', 'return',
 'try', 'while', 'with', 'yield']

予約語 (Ruby)

BEGIN    class    ensure   nil      self     when
END      def      false    not      super    while
alias    defined? for      or       then     yield
and      do       if       redo     true     __LINE__
begin    else     in       rescue   undef    __FILE__
break    elsif    module   retry    unless   __ENCODING__
case     end      next     return   until

時々、endnextが変数やメソッドに使用されて困ることがあります。

ただし接頭辞$, @、@@が先頭についたものは予約語とは見なされません。

_を先頭につけることもよくやります。
