Python字典键，value返回多个值

def get_values(dictionary, key):
    if key in dictionary:
        return dictionary[key]
    else:
        return []

# 示例用法
my_dict = {'name': 'Alice', 'age': 25, 'gender': 'female'}
values = get_values(my_dict, 'age')
print(values)  # 输出：[25]

def get_values(dictionary, key):
    if key in dictionary:
        return tuple(dictionary[key])
    else:
        return ()

# 示例用法
my_dict = {'name': 'Alice', 'age': 25, 'gender': 'female'}
values = get_values(my_dict, 'name')
print(values)  # 输出：('Alice',)

def get_values(dictionary, key):
    if key in dictionary:
        return set(dictionary[key])
    else:
        return set()

# 示例用法
my_dict = {'name': 'Alice', 'age': 25, 'gender': 'female'}
values = get_values(my_dict, 'gender')
print(values)  # 输出：{'f', 'e', 'm', 'a', 'l'}
