numpy.isrealobj() in Python Last Updated : 07 Aug, 2019 Comments Improve Suggest changes Like Article Like Report numpy.isrealobj(array) : This logical function helps to checks if the array has no complex type or array has a complex number. Even if imaginary part is equal to zero, it is not considered to be a Real Object. Parameters : array : [array_like]Input array or object whose elements, we need to test. Return : True, if the input array hasn't any complex element; otherwise False Code 1 : Python # Python program explaining # isrealobj() function import numpy as np in_array = [1, 3, 5, 4] print ("Input array : ", in_array) output_value = np.isrealobj(in_array) print ("\nIs real : ", output_value) Output : Input array : [1, 3, 5, 4] Is real : True Code 2 : Python # Python Program illustrating # numpy.isrealobj() method import numpy as geek # Returns True/False value for each element a = geek.arange(20).reshape(5, 4) print("Is real : ", geek.isrealobj(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 real : ", geek.isrealobj(b)) b = [[1j], [3]] print("\nIs real : ", geek.isrealobj(b)) Output : Is real : True class 'complex' Is real : True Is real : False References : https://docs.scipy.org/doc/numpy-1.13.0/reference/generated/numpy.isrealobj.html#numpy.isrealobj .
