如何查找某个产品的未知选项数量的所有组合？

def find_combinations(option_values):
    num_options = len(option_values)
    combinations = []
    
    # 计算组合数量
    total_combinations = 1
    for num_values in option_values:
        total_combinations *= num_values
    
    # 列举所有组合
    for i in range(total_combinations):
        combination = []
        for j in range(num_options):
            option_index = i % option_values[j]
            combination.append(option_index)
            i //= option_values[j]
        combinations.append(combination)
    
    return combinations

# 示例用法
option_values = [3, 2, 4]  # 假设有3个选项，分别有3、2、4个可能的取值
combinations = find_combinations(option_values)
print(combinations)
