numpy.iscomplexobj() in Python Last Updated : 11 May, 2021 Comments Improve Suggest changes Like Article Like Report 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 References : https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.iscomplexobj.html#numpy.iscomplexobj Comment More infoAdvertise with us Next Article numpy.iscomplexobj() in Python M mohit gupta_omg :) Follow Improve Article Tags : Python Python-numpy Python numpy-Logic Functions Practice Tags : python Similar Reads 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.
