请尝试实现Beverage、Tea、Coffee、Beer类并给出简单的测试

Beverage类：

class Beverage:
    def __init__(self, name, price):
        self.name = name
        self.price = price

    def get_name(self):
        return self.name

    def get_price(self):
        return self.price

    def __str__(self):
        return f"{self.name} - ${self.price:.2f}"

Tea类：

class Tea(Beverage):
    def __init__(self, name, price, type):
        super().__init__(name, price)
        self.type = type

    def get_type(self):
        return self.type

    def __str__(self):
        return f"{self.name} - {self.type} - ${self.price:.2f}"

Coffee类：

class Coffee(Beverage):
    def __init__(self, name, price, size):
        super().__init__(name, price)
        self.size = size

    def get_size(self):
        return self.size

    def __str__(self):
        return f"{self.name} - {self.size} - ${self.price:.2f}"

Beer类：

class Beer(Beverage):
    def __init__(self, name, price, alcohol_content):
        super().__init__(name, price)
        self.alcohol_content = alcohol_content

    def get_alcohol_content(self):
        return self.alcohol_content

    def __str__(self):
        return f"{self.name} - {self.alcohol_content}% - ${self.price:.2f}"

测试：

tea = Tea("Green Tea", 3.5, "Loose Leaf")
print(tea.get_name())  # Green Tea
print(tea.get_type())  # Loose Leaf
print(tea.get_price())  # 3.5
print(tea)  # Green Tea - Loose Leaf - $3.50

coffee = Coffee("Latte", 4.2, "Medium")
print(coffee.get_name())  # Latte
print(coffee.get_size())  # Medium
print(coffee.get_price())  # 4.2
print(coffee)  # Latte - Medium - $4.20

beer = Beer("IPA", 5.8, 6.5)
print(beer.get_name())  # IPA
print(beer.get_alcohol_content())  # 6.5
print(beer.get_price())  # 5.8
print(beer)  # IPA - 6.5% - $5.80
