如何检查某项是否在字典中的列表中？

def check_item_in_list_of_dict(item, list_of_dict):
    for dictionary in list_of_dict:
        if item in dictionary.values():
            return True
    return False

# 定义一个包含字典的列表
employees = [
    {"name": "Alice", "age": 25, "department": "HR"},
    {"name": "Bob", "age": 30, "department": "Engineering"},
    {"name": "Charlie", "age": 35, "department": "Sales"}
]

# 检查特定项是否在列表中的字典中出现
print(check_item_in_list_of_dict("Alice", employees))  # 输出: True
print(check_item_in_list_of_dict("Marketing", employees))  # 输出: False
