如何在Python中调用函数的特定返回值？

def get_user_info():
    name = "John"
    age = 25
    email = "john@example.com"
    return name, age, email

# 调用函数并接收返回值
user_name, user_age, user_email = get_user_info()

# 访问特定返回值
print(user_name)   # 输出：John
print(user_age)    # 输出：25
print(user_email)  # 输出：john@example.com

def get_user_info():
    user_info = {
        "name": "John",
        "age": 25,
        "email": "john@example.com"
    }
    return user_info

# 调用函数并接收返回值
user_info = get_user_info()

# 访问特定返回值
print(user_info["name"])   # 输出：John
print(user_info["age"])    # 输出：25
print(user_info["email"])  # 输出：john@example.com

class UserInfo:
    def __init__(self, name, age, email):
        self.name = name
        self.age = age
        self.email = email

def get_user_info():
    name = "John"
    age = 25
    email = "john@example.com"
    return UserInfo(name, age, email)

# 调用函数并接收返回值
user_info = get_user_info()

# 访问特定返回值
print(user_info.name)   # 输出：John
print(user_info.age)    # 输出：25
print(user_info.email)  # 输出：john@example.com
