numpy.iscomplex() in Python

About :
numpy.iscomplex(array) : Test element-wise whether it is a complex number or not(not infinity or not Not a Number) and return the result as a boolean 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]]
