numpy.asscalar () in Python

NumPy | Python Methods and Functions

numpy.asscalar() is used when we want to convert an array of size 1 to its scalar equivalent.

Syntax : numpy.asscalar (arr)

Parameters:
arr: [ndarray] Input array of size 1.

Return: Scalar representation of arr. The output data type is the same type returned by the input`s item method.

Code # 1: Work

# Python program explaining
# numpy.asscalar () function

  

import numpy as geek

# create an array of size 1

in_arr = geek.array ([ 8 ])

 

print ( "Input array:" , in_arr)

 

  

out_scalar = geek .asscalar (in_arr)

print ( "output scalar from input array:" , out_scalar) 

Output:

 Input array: [8] output scalar from input array: 8 

Code # 2:

# Python program explaining
# numpy. asscalar () function

import numpy as geek

 

in_list = [ 2 ]

 
# change the list to size 1 array

arr = geek.array (in_list ) 

 

print ( " Input array from list: " , arr)

 
# changing the array to a scalar

scalar = geek.asscalar (arr)

 

print ( "output scalar from input list: " , scalar) 

Output:

 Input ar ray from list: [2] output scalar from input list: 2
