Python numpy数组串联

Question

I have a doubt in numpy array concatenation. 我对numpy数组串联有疑问。

For eg, 例如

If I have 如果我有

a = [ 1, 2, 3]
b = [4, 5, 6, 7]
c= [5, 2]

Could I concatenate arrays of different size??? 我可以串联不同大小的数组吗？？？ If so, How could it be possible? 如果是这样，怎么可能？

Answer 1

Yes, You can using numpy.concatenate 是的，您可以使用numpy.concatenate

import numpy as np
a = [ 1, 2, 3]
b = [4, 5, 6, 7]
c= [5, 2]
d = np.concatenate((a, b, c))
