如何按特定顺序从列表中获取唯一值？

def get_unique_values_in_order(lst):
    seen = set()
    result = []
    for item in lst:
        if item not in seen:
            seen.add(item)
            result.append(item)
    return result

# 示例列表
my_list = [3, 1, 2, 2, 4, 1, 5, 3]

# 按特定顺序获取唯一值
unique_values = get_unique_values_in_order(my_list)
print(unique_values)  # 输出: [3, 1, 2, 4, 5]

def get_unique_values_in_order_optimized(lst):
    seen = set()
    result = []
    for item in lst:
        if item not in seen:
            seen.add(item)
            result.append(item)
    return result

# 示例列表
my_list = [3, 1, 2, 2, 4, 1, 5, 3]

# 按特定顺序获取唯一值
unique_values = get_unique_values_in_order_optimized(my_list)
print(unique_values)  # 输出: [3, 1, 2, 4, 5]
