在Ruby 中,循环是用于重复执行代码块的重要结构。Ruby 提供了多种循环方式,包括 loop、while、until、for、times、each 等。以下是详细说明和示例: 1. loop 循环 loop 是一个无限循环,需手动通过 break 退出。 语法: ruby loop do # 循环体 break if condition # 退出条件 end 示例: ruby i = 0 loop do...

It’s common practice to use a break statement to terminate an infinite loop. while True: print("Still going…") if some_cond: break # we never get here print("We shouldn't be here") # we end up here after breaking print("Done.") Copy A close relative of break statements are ...
