如何生成元素为随机数的1000个2x2矩阵？

import random

# 生成1000个2x2矩阵的函数
def generate_matrices():
    matrices = []
    for _ in range(1000):
        matrix = [[random.randint(1, 100) for _ in range(2)] for _ in range(2)]
        matrices.append(matrix)
    return matrices

# 调用函数生成矩阵
matrices = generate_matrices()

# 打印前5个矩阵
for i in range(5):
    print(f"Matrix {i+1}:")
    for row in matrices[i]:
        print(row)
    print()
