如何编写一段代码来检测数字python中的重复数字？

def find_duplicates(nums):
    seen = set()
    duplicates = set()
    
    for num in nums:
        if num in seen:
            duplicates.add(num)
        else:
            seen.add(num)
    
    return list(duplicates)

numbers = [1, 2, 3, 4, 5, 2, 6, 7, 8, 9, 1, 10]
duplicates = find_duplicates(numbers)
print(duplicates)

[1, 2]
