python - 无法在 python 中制作一个 10x10 的矩阵

问题描述

我想编写一个简单的脚本来创建一个 10x10 的矩阵，其中从 1 到 99 的所有数字每次都附加到一个包含 10 个元素的列表组中。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)

这是输出：

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

我添加了 print(lista2) 以检查其中每次只有 10 个元素。

标签： python

解决方案

lista = []
z = 0

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

print(lista)

要不就：

lista = [[10*i+j for j in range(10)] for i in range(10)]
print(lista)
