Python | numpy.issubdtype() function

numpy.issubdtype() function is used to determine whether the first argument is a typecode lower/equal in type hierarchy from second argument.If the first argument is lower or equal it returns true, otherwise it returns false.

Syntax : numpy.issubdtype(arg1, arg2)

Parameters :
arg1, arg2 : [dtype_like] dtype or string representing a typecode.

Return : [bool] Boolean result.

Code #1 :

# Python program explaining
# numpy.issubdtype() function

# importing numpy
import numpy as geek

# selecting the argument

arg1 = geek.int64
arg2 = geek.int32

# output boolean value
out_val = geek.issubdtype(arg1, arg2)
print ("Is the first argument lower: ", out_val)

Output :

Is the first argument lower:  False

Code #2 :

# Python program explaining
# numpy.issubdtype() function

# importing numpy
import numpy as geek

# selecting the argument

arg1 ='S2'
arg2 = geek.string_

# output boolean value
out_val = geek.issubdtype(arg1, arg2)
print ("Is the first argument lower: ", out_val)

Output :

Is the first argument lower:  True
