Python | numpy.issubsctype() function

Last Updated : 14 Mar, 2019

numpy.issubsctype() function is used to determine whether the first argumentis a subclass of the second argument.If the first argument is a subclass of the second argument it returns true, otherwise it returns false.

Syntax : numpy.issubsctype(arg1, arg2)

Parameters :
arg1, arg2 : dtype or dtype specifier.

Return : [bool] Boolean result.

Code #1 :

# Python program explaining 
# numpy.issubsctype() function 
  
# importing numpy 
import numpy as geek 
  
# selecting the argument 
  
arg1 = geek.array([1.0, 2.5, 3.9]) 
arg2 = geek.int
  
# output boolean value 
out_val = geek.issubsctype(arg1, arg2) 
print ("Is the first argument subclass of the second argument: ", out_val)  

Output :

Is the first argument subclass of the second argument:  False

Code #2 :

# Python program explaining 
# numpy.issubsctype() function 
  
# importing numpy 
import numpy as geek 
  
# selecting the argument 
  
arg1 = geek.array([1.0, 2.5, 3.9]) 
arg2 = geek.float
  
# output boolean value 
out_val = geek.issubsctype(arg1, arg2) 
print ("Is the first argument subclass of the second argument: ", out_val)  

Output :

Is the first argument subclass of the second argument:  True
