从数组中删除NaN值 [英] Removing nan values from an array

问题描述

我想弄清楚如何从我的数组中删除NaN值。它看起来是这样的：

I want to figure out how to remove nan values from my array. It looks something like this:

x = [1400, 1500, 1600, nan, nan, nan ,1700] #Not in this exact configuration

我是比较新的蟒蛇，所以我还在学习。任何提示？

I'm relatively new to python so I'm still learning. Any tips?

推荐答案

如果您正在使用numpy的为你的阵列，也可以使用

If you're using numpy for your arrays, you can also use

x = x[numpy.logical_not(numpy.isnan(x))]

等价

x = x[~numpy.isnan(x)]
