生成一段全排序的python代码

以下是生成全排序的Python代码：

def permute(nums):
    """
    :type nums: List[int]
    :rtype: List[List[int]]
    """
    if len(nums) == 0:
        return []
    if len(nums) == 1:
        return [nums]
    result = []
    for i in range(len(nums)):
        n = nums[i]
        rem = nums[:i] + nums[i+1:]
        for p in permute(rem):
            result.append([n] + p)
    return result

# 示例
print(permute([1, 2, 3]))

输出结果为：

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