将值分配给numpy中的多个片 [英] Assign value to multiple slices in numpy

问题描述

在Matlab中，您可以将值分配给同一列表的多个切片:

In Matlab, you can assign a value to multiple slices of the same list:

>> a = 1:10

a =

     1     2     3     4     5     6     7     8     9    10

>> a([1:3,7:9]) = 10

a =

    10    10    10     4     5     6    10    10    10    10

如何用numpy数组在Python中执行此操作?

How can you do this in Python with a numpy array?

>>> a = np.arange(10)

>>> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

>>> a[1:3,7:9] = 10
IndexError: too many indices

推荐答案

a = np.arange(10)
a[[range(3)+range(6,9)]] = 10
#or a[[0,1,2,6,7,8]] = 10 

print a

应该工作，我想...我不知道那是你想要的

that should work I think ... I dont know that its quite what you want though
