numpy.put() in Python (original) (raw)

Last Updated : 08 Mar, 2024

The numpy.put() function replaces specific elements of an array with given values of p_array. Array indexed works on flattened array.

Syntax: numpy.put(array, indices, p_array, mode = 'raise')

Parameters :

array : array_like, target array indices : index of the values to be fetched p_array : array_like, values to be placed in target array mode : [{‘raise’, ‘wrap’, ‘clip’}, optional] mentions how out-of-bound indices will behave raise : [default]raise an error wrap : wrap around clip : clip to the range

Python

import numpy as geek

a = geek.arange( 5 )

geek.put(a, [ 0 , 2 ], [ - 44 , - 55 ])

print ( "After put : \n" , a)

Output :

After put : [-44, 1, -55, 3, 4]

Python

import numpy as geek

a = geek.arange( 5 )

geek.put(a, 22 , - 5 , mode = 'clip' )

print ( "After put : \n" , a)

Output :

array([ 0, 1, 2, 3, -5])
