Python中的 numpy.put()
numpy.put()函数用给定的 p_array 值替换数组的特定元素。数组索引适用于扁平数组。
Syntax: numpy.put(array, indices, p_array, mode = 'raise')
参数 :
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

# numpy.put()
import numpy as geek
a = geek.arange(5)
geek.put(a, [0, 2], [-44, -55])
print("After put : \n", a)
Python
# Python Program explaining

import numpy as geek
a = geek.arange(5)
geek.put(a, 22, -5, mode='clip')
print("After put : \n", a)
输出 :
After put :
[-44, 1, -55, 3, 4]
