python: 配列の結合

Posted at

pythonで配列を結合する方法

以下のように，ndarrayの場合はnp.r_[配列A, 配列B]で結合可能．
listの場合は + を用いることで結合可能．

In [1]: import numpy as np

In [2]: a = np.array([1,2,3])

In [3]: b = np.array([4,5,6])

In [4]: np.r_[a, b]
Out[4]: array([1, 2, 3, 4, 5, 6])

In [5]: a = [1,2,3]

In [6]: b = [4,5,6]

In [7]: a + b
Out[7]: [1, 2, 3, 4, 5, 6]
