python三只小猪称体重

以下是一个示例代码，用于演示如何使用Python来表示和比较三只小猪的体重：

class Pig:
    def __init__(self, name, weight):
        self.name = name
        self.weight = weight

# 创建三只小猪的实例
pig1 = Pig("小猪1", 50)
pig2 = Pig("小猪2", 60)
pig3 = Pig("小猪3", 70)

# 比较三只小猪的体重
if pig1.weight > pig2.weight and pig1.weight > pig3.weight:
    print(pig1.name, "体重最大")
elif pig2.weight > pig1.weight and pig2.weight > pig3.weight:
    print(pig2.name, "体重最大")
else:
    print(pig3.name, "体重最大")

输出结果将是体重最大的小猪的名字。
