numpy.iscomplexobj() in Python (original) (raw)

Last Updated : 11 May, 2021

numpy.iscomplexobj(array) : This logical function helps to checks for the complex type of an array or array of a complex number. Even if imaginary part is equal to zero, it is considered to be an Complex Object.

Parameters :

array : [array_like]Input array or object whose elements, we need to test.

Return :

True, if the input array has a complex element; otherwise False

Code 1 :

Python

import numpy as np

in_array = [ 1 , 3 , 5 , 4 ]

print ( "Input array : " , in_array)

output_value = np.iscomplexobj(in_array)

print ( "\nIs complex : " , output_value)

Output :

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

Is complex : False

Code 2 :

Python

import numpy as geek

a = geek.arange( 20 ).reshape( 5 , 4 )

print ( "Is complex : \n" , geek.iscomplexobj(a))

b = geek.arange( 20 ).reshape( 5 , 4 ).dtype = complex

print ( "\n" ,b)

print ( "\nIs complex : " , geek.iscomplexobj(b))

b = [[ 1j ],

`` [ 3 ]]

print ( "\nIs complex : \n" , geek.iscomplexobj(b))

Output :

Is complex : False

class 'complex'

Is complex : False

Is complex : True
