python两个二维数组合并

要将两个二维数组合并，可以使用NumPy库的concatenate函数。例如，可以使用以下代码将两个二维数组iris_joint和iris_joint2合并成一个新的二维数组：

import numpy as np

combined_array = np.concatenate((iris_joint, iris_joint2), axis=1)
print(combined_array)

这样，combined_array就是合并后的结果。请注意，合并操作是在纵轴(axis=1)方向上进行的，也就是按列合并。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
