numpy.iscomplexobj() in Python

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

# 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

Code 2 :

Python

# 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
