如何循环数组以创建特定的6位数字组合

def generate_combinations():
    digits = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]
    combinations = []

    for digit1 in digits:
        for digit2 in digits:
            for digit3 in digits:
                for digit4 in digits:
                    for digit5 in digits:
                        for digit6 in digits:
                            combination = str(digit1) + str(digit2) + str(digit3) + str(digit4) + str(digit5) + str(digit6)
                            combinations.append(combination)

    return combinations

# 调用函数生成所有的六位数字组合
all_combinations = generate_combinations()

# 输出结果
for combination in all_combinations:
    print(combination)
