numpy.dtype.subdtype() function – Python

Last Updated : 18 Jun, 2020

numpy.dtype.subdtype() function returns Tuple(item_dtype, shape) if this dtype describes a sub-array, and None otherwise.

Syntax : numpy.dtype.subdtype(type) type : [dtype] The input data-type. Return : Return Tuple(item_dtype, shape) if this dtype describes a sub-array, and None otherwise.

Code #1 :

Python3

# Python program explaining
# numpy.dtype.subdtype() function
       
# importing numpy as geek 
import numpy as geek 
   
x = geek.dtype('8f')
 
gfg = x.subdtype
 
print (gfg)

Output :

(dtype('float32'), (8, ))

Code #2 :

Python3

# Python program explaining
# numpy.dtype.subdtype() function
       
# importing numpy as geek 
import numpy as geek 
   
x = geek.dtype('i2')
 
gfg = x.subdtype
 
print (gfg)

Output :

None

type() function in Python

The type() function is mostly used for debugging purposes. Two different types of arguments can be passed to type() function, single and three arguments. If a single argument type(obj) is passed, it returns the type of the given object. If three argument types (object, bases, dict) are passed, it re
