在列表中查找每个系统出现一次的值

def find_unique_systems(lst):
    system_count = {}
    unique_systems = []

    # 计算每个系统出现的次数
    for system in lst:
        if system in system_count:
            system_count[system] += 1
        else:
            system_count[system] = 1

    # 找出出现一次的系统
    for system, count in system_count.items():
        if count == 1:
            unique_systems.append(system)

    return unique_systems

# 示例用法
systems = ["Windows", "Linux", "Windows", "Mac", "Linux", "Windows"]
unique_systems = find_unique_systems(systems)
print(unique_systems)
