How I Can Replace The XNA Value With NAN In Dataframe Using Replace
Numpy nanmean numpy nanmean a axis None dtype None out None keepdims no value where no value source Compute the arithmetic mean along the specified axis ignoring NaNs Returns the average of the array elements The average is taken over the flattened array by default otherwise over the specified axis Numpy nanmean NumPy v1 26 Manual. Method 1 Using numpy isnan with a Conditional Statement The numpy isnan function generates a boolean array indicating whether an element is NaN Combined with conditional indexing this method allows us to selectively replace NaN values with zeros Here s an example import numpy as np Step 2 Set NaN values in the array to the mean using boolean indexing Use the numpy isnan function to check whether a value in the array is NaN or not If it is set it to the mean value use the numpy nanmean function to get the mean of a Numpy array with NaN values Let s replace all occurrences of NaN in the above array with
