此函数在不更改数据的情况下为数组提供了新的维度,它接受以下参数-

numpy.reshape(arr, newshape, order')
Sr.No. 描述
1

arr

数组

2

newshape

int或int的元组,新维度应与原始维度兼容

3

order

如果数组存储在类似Fortran的连续内存中,则" C"表示C风格," F"表示Fortran风格," A"表示类似Fortran的顺序。

import numpy as np
a = np.arange(8)
print 'The original array:'
print a
print '\n'

b = a.reshape(4,2)
print 'The modified array:'
print b

其输出如下-

The original array:
[0 1 2 3 4 5 6 7]

The modified array:
[[0 1]
 [2 3]
 [4 5]
 [6 7]]
