By Pranit Sharma Last updated : May 23, 2023 Suppose we need to create a NumPy array of length n, and each element of this array would be e a single value (say 5). Removing NaN values from a given NumPy array To remove NaN values from a given NumPy array, you can use a method provided by NumPy called the full() method. This method is better than the empty() followed by the fill() method. This is arguably the way of creating an array filled with certain values because it explicitly describes what is being achieved. Let us understand with the help of an example, Python program to remove NaN values from a given NumPy array # Import numpy import numpy as np # Creating a numpy array arr = np . array([ 1 , 2 , np . NaN, 4 , np . NaN, 8 ]) # Display original array print ( "Orignal array: \n " ,arr, " \n " ) # Extracting non null values res = arr[ ~ np . isnan(arr)] # Display Result print ( "Result: \n " ,res, " \n " ) Output Python NumPy Programs » Advertisement Advertisement
