最满意答案

恐怕除了某些人会建议针对一个“匿名”变量_ ，你不会得到比Python更漂亮的东西。 这是做你想做的Pythonic成语。

（这可能会让新手感到困惑，因为它可能会被误认为是特殊的语法，我使用它，但是仅在我的代码的“专家部分”中使用它，我也经常遇到它，但意见似乎仍然有点分歧在这一个上。）

I'm afraid you're not gonna get it any prettier than that in Python, except that some people would advise against _ for an "anonymous" variable. This is the Pythonic idiom for doing what you want.

(The _ can be considered confusing to novices because it can be mistaken for special syntax. I use it, but only in the "expert parts" of my code. I also encounter it more and more often, but opinion still seems a bit divided on this one.)
