numpy.iscomplexobj() in Python

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
