无法在python中制作10x10矩阵

Question

我想写一个简单的脚本来创建矩阵10x10，所有数字从1到99每次附加到一个由10个元素组成的列表组。我期望的结果是list [[1,2,3,4,5,6,7,8,9]，[10,11,12,13,14,15,16,17,18,19]。 ..]但是输出很奇怪：

这里是脚本：

lista=[]
lista2=[]
z=0
for a in range (10):
    lista2.clear()
    for x in range (10):
        lista2.append(z)
        z+=1
    print(lista2)
    lista.append(lista2)
    print(lista)

这里是输出：

[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
[[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]]

**added print(lista2) to chechk that there were only 10 elements each time in it`enter code here`

Answer 1

lista = []
z = 0

for i in range(10):
    lista2 = []
    for j in range(10):
        lista2.append(z)
        z += 1
    lista.append(lista2)

print(lista)
