这一数组属性返回一个包含数组维度的元组，它也可以用于调整数组大小

查看数组形状: .shape

import numpy as np

a = np.array([[1,2,3],[4,5,6]])

print a.shape

(2, 3)

# 这会调整数组大小

import numpy as np

a = np.array([l1,2,31,[4,5,611) a.shape = (3,2)

print a

[[1, 2)

[3, 4]

[5, 6]]

修改数组形状: .reshape()

import numpy as np

a = np.array([[1,2,3],[4,5,6]])

b = a.reshape(3,2)

print b

[[1, 2)

[3, 4)

[5, 6]]
