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

Python program explaining

iscomplexobj() function

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

Python Program illustrating

numpy.iscomplexobj() method

import numpy as geek

Returns True/False value for each element

a = geek.arange(20).reshape(5, 4) print("Is complex : \n", geek.iscomplexobj(a))

Returns True/False value as ans

because we have mentioned dtpe in the beginning

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
