In this python numpy program, we will test element-wise for NaN of a given array using NumPy.
Steps to solve the program
- Import the numpy library as np.
- Create an array using np.array().
- test element-wise for NaN of a given array using np.isnan().
- It will return True if an element is NaN (i.e. not a number).
- Print the output.
import numpy as np
x = np.array([2,4,np.nan,7])
print(np.isnan(x))
Output :
[False False True False]
