内部lambda的Python循环 [英] Python loop for inside lambda

问题描述

在我的代码中，我需要尽可能简化我的代码行. 我想我还不够清楚-它需要是一行代码. 我需要在lambda表达式中放入for循环，诸如此类:

In my code I need to simplify as much as possible my line of code. I think I'm not clear enough - it needs to be one line of code. I need to put a for loop inside a lambda expression, something like that:

x = lambda x: (for i in x : print i)

我只是不知道如何实现它. 谢谢！

I just do not know how to make it happen. Thanks!

推荐答案

由于for循环是一条语句(Python 2.x中的print也是这样)，因此您不能将其包括在lambda表达式中.相反，您需要在sys.stdout上同时使用write方法和join方法.

Since a for loop is a statement (as is print, in Python 2.x), you cannot include it in a lambda expression. Instead, you need to use the write method on sys.stdout along with the join method.

x = lambda x: sys.stdout.write("\n".join(x) + "\n")
