numpy.iscomplex() in Python
  • Last Updated : 23 Oct, 2020

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]]
