rubyのfor文にはeach_index的なものはないのでしょうか？ ### pythonfor ary = ["taguti","fkoji"] for i in range(len(ary)): print(i) ### rubyeach_index ary = ["taguti","fkoji"] ary.each_index{|i| p i} ### rubyfor for i in ary.length p i# --- NG

Rubyfor

*
* foreach



each_index


ary = %w[taguti fkoji]
ary.each_index{|i| p i}
