如何检查列表中所有可能的数字组合？

def find_combinations(nums, prefix=[]):
    if len(nums) == 0:
        print(prefix)  # 输出找到的组合
    else:
        for i in range(len(nums)):
            new_prefix = prefix + [nums[i]]
            new_nums = nums[:i] + nums[i+1:]
            find_combinations(new_nums, new_prefix)

# 测试
nums = [1, 2, 3]
find_combinations(nums)

[1, 2, 3]
[1, 3, 2]
[2, 1, 3]
[2, 3, 1]
[3, 1, 2]
[3, 2, 1]
