Python numpy.put()用法及代码示例

numpy.put(数组，索引，p_array，模式=“提高”)：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。
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 Program explaining 
# numpy.put() 
  
import numpy as geek 
  
a = geek.arange(5) 
geek.put(a, [0, 2], [-44, -55]) 
print("After put : \n", a)

输出：

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

# 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)

输出：

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