numpy.put() in Python

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

# Python Program explaining
# numpy.put()

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

# Python Program explaining
# numpy.put()

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])
