关于#python#的题目，请各位专家解答！我前面四道做出来了，最后一道不会

Question

1.设计一个Human类，具有姓名（name）和体重（weight）属性，和跑步（run）方法和吃饭（eat）方法，每个方法打印一行字，xx（此人的名字）正在跑步/吃饭。

2.以Human类为父类，派生出Man类，Man每次跑步体重减少0.3kg，每次吃饭体重增加0.2kg。初始化Man的对象的时候，随机初始化设置他的体重为60-90kg。

3.以Human类为父类，派生出Woman类，Woman每次跑步体重减少0.2kg，每次吃饭体重增加0.1kg。初始化Woman的对象的时候，随机初始化设置他的体重为40-60kg。

4.实例化两个对象，男女各一个，自行取名，打印出他/她们的名字和体重。

5.让他/她们各自度过30天，男的每天跑1次步，吃3顿饭，女的每天跑2次步，吃2顿饭。打印出30天后各自的名字和体重。
