如何从关联数组中只打印一次部门名称

# 示例关联数组
departments = {
    "001": "Sales",
    "002": "Marketing",
    "003": "HR",
    "004": "Finance",
    "005": "Sales",
    "006": "HR"
}

# 创建一个空集合
printed_departments = set()

# 遍历关联数组
for department in departments.values():
    # 检查部门名称是否已经打印过
    if department not in printed_departments:
        # 打印部门名称
        print(department)
        # 将部门名称添加到已打印集合中
        printed_departments.add(department)

Sales
Marketing
HR
Finance
