如下图所示。有人能告诉我为什么长度是4? 我希望长度为3(因为3个数组),但我不知道4的来源是什么?

A, W, b = linear_forward_test_case()

Z, linear_cache = linear_forward(A, W, b)

caches.append(linear_cache)

print("Z = " + str(Z))

print("cache =" + str(linear_cache))
print("Length of caches list = " + str(len(caches)))

结果

Z = [[ 3.26295337 -1.23429987]]
cache =(array([[ 1.62434536, -0.61175641],
       [-0.52817175, -1.07296862],
       [ 0.86540763, -2.3015387 ]]), array([[ 1.74481176, -0.7612069 ,  0.3190391 ]]), array([[-0.24937038]]))
Length of caches list = 4
