如何创建m-m数组的nxn数组？

n = 4  # 数组大小为n x n
m = 2  # 子数组大小为m x m

# 创建n x n数组
A = [[0] * n for _ in range(n)]

# 遍历数组元素
for i in range(n):
    for j in range(n):
        # 判断行和列是否都是m的倍数
        if i % m == 0 and j % m == 0:
            A[i][j] = 1
        else:
            A[i][j] = 0

# 打印数组
for row in A:
    print(row)

[1, 0, 1, 0]
[0, 0, 0, 0]
[1, 0, 1, 0]
[0, 0, 0, 0]
