从由i，j标记的字典中的内容创建一个数值矩阵

def create_matrix_from_dict(dict_data):
    max_i = max([key[0] for key in dict_data.keys()])
    max_j = max([key[1] for key in dict_data.keys()])
    
    matrix = [[0] * (max_j + 1) for _ in range(max_i + 1)]
    
    for key, value in dict_data.items():
        matrix[key[0]][key[1]] = value
    
    return matrix

# 示例字典数据
dict_data = {(0, 0): 1, (0, 1): 2, (1, 0): 3, (1, 1): 4}

# 创建数值矩阵
matrix = create_matrix_from_dict(dict_data)

# 打印数值矩阵
for row in matrix:
    print(row)

[1, 2]
[3, 4]
