将多个numpy数组合并为一个

Question

我有这个O / P，如下图所示

我的O / P包含大约100多个numpy数组，如上所示。我正在尝试将所有这些100多个numpy数组合成一个numpy数组，以便进一步处理数据。关于如何完成任何想法????我正在使用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]])
