组合多个阵列numpy的成一个

Question

我已经如图此O/P在下面的PIC

我的O/P由周围100+ numpy的阵列等上面显示的一个。我试图将所有这些100多个numpy数组合并成一个numpy数组，以便进一步处理数据。任何想法如何做到这一点？我使用python V3.4

您可以使用hstack和vstack：

In [29]: hstack((arange(10) for _ in range(10))) 
Out[29]: 
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 
    3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 
    6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 
    9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 0, 1, 
    2, 3, 4, 5, 6, 7, 8, 9]) 

In [30]: vstack((arange(10) for _ in range(10))) 
Out[30]: 
array([[0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9], 
    [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]])
