My dataset contains values like NaN, inf, etc. During data preprocessing, I want to remove these kinds of values that I have to check in my data. I’m a beginner and don’t know much about handling them. During the research, I found a method but I’m not sure about its working.

Can someone explain the code I showed above and share with me some ways to check these special numbers in my data?You can use the `isfinite()`

method too for doing the same thing, it is an alternate method for your task and this function returns a Boolean array of the same shape as the input array, where each element is `True`

if the corresponding element in the input array is a finite number (i.e., not NaN or infinity), and `False`

otherwise. Here is a code that uses this function:
