1.python 中 return用法 The key word "return" which should be used only in a function in Python programming language.If you use it in a "for" loop or else,an error like "SyntaxError: 'return' outside function" is supposed to appears .· return在python中只能被用在函数当中,如果用在loop...
python循环返回python返回循环.return pass:为了保持程序结构的完整性,不做什么事,一般做占位语句for i in range(5): print(i) pass print(i*2) #下边是输出结果 0 0 1 2 2 4 3 6 4 8return:结束函数,返回参数(需要注意的是,当执行return之后,函数return之后的语句将不会再继续执行下去,而是返回第一个...

foriinrange(2): print'test ~' return'Target !' s=test() prints # 输出结果 test~ test~ Target! 这样对比这来看, 应该能更好地理解为什么说early return能够减少嵌套的层数吧~ 有疑问欢迎留言讨论~ 谈谈深坑 刚才花了比较长的篇幅去介绍return, 相信看到这里, 对于return应该有比较基本的理解了! 所以来...
1、forloop方法: defodd_numbers(n):forxinrange(n):if(x % 2) == 1:yieldx num= odd_numbers(10)foriinnum:print(i) 2、next()方法: defodd_numbers(n):forxinrange(n):if(x % 2) == 1:yieldx num= odd_numbers(10)print(next(num))print(next(num))print(next(num))print(next(nu...
