numpy.iscomplex() in Python

The numpy.iscomplex() function tests element-wise whether it is a complex number or not(not infinity or not Not a Number) and returns the result as a boolean array. Syntax : 

numpy.iscomplex(array)

Parameters : 

array : [array_like] Input array whose element we want to test

Return : 

boolean array containing the result

Code 1 : 

# Python Program illustrating # numpy.iscomplex() method import numpy as geek print("Is Complex : ", geek.iscomplex([1+1j, 1+0j]), "\n") print("Is Complex : ", geek.iscomplex([0+1j, 0]), "\n") 

Output : 

Is Complex : [ True False] Is Complex : [ True False] 

Code 2 : 

# Python Program illustrating # numpy.iscomplex() method import numpy as geek # Returns True/False value for each element  a = geek.arange(20).reshape(5, 4) print("Is complex : \n", geek.iscomplex(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.iscomplex(b)) b = [[1j], [3]] print("\nIs complex : \n", geek.iscomplex(b)) 

Output : 

Is complex : [[False False False False] [False False False False] [False False False False] [False False False False] [False False False False]] Is complex : False Is complex : [[ True] [False]]
