TypeError: 'list' object is not callable

Question

代码：

import numpy as np
x_12 = np.array([[1,2,3],[4,5,6]])
y_54 = np.array([[6,23],[-1,7],[8,9]])
x.dot(y)
np.dot(x, y)

报错信息：

      5 np.dot(x, y)

代码没贴全？还是本来就写错了

import numpy as np
x = np.array([[1,2,3],[4,5,6]])
y = np.array([[6,23],[-1,7],[8,9]])
x.dot(y)
print(np.dot(x, y))
