  • Last Updated : 29 Nov, 2018

numpy.isscalar(num) : This is a logical function that returns true if the type of input num is scalar.

Parameters :

num : Input argument of any type and shape.

Return :

True, if input is scalar; else False

Code 1 : Working




# Python program explaining
# isscalar() function
import numpy as np
  
in_array = [1, 3, 5, 4]
print ("Input array : ", in_array)
  
isscalar_values = np.isscalar(in_array)
print ("\nIs scalar : ", isscalar_values)
  
# input
print ("\nisscalar(7) : ", np.isscalar(7))
  
# list input 
print ("\nisscalar([7]) : ", np.isscalar([7]))


Output :



Input array :  [1, 3, 5, 4]

Is scalar :  False

isscalar(7) :  True

isscalar([7]) :  False
