Python，刚讲的，，问问怎么做

class Man():
    def __init__(self,name, age, weight, height):
        self.name = name
        self.age = age
        self.weight = weight
        self.heigh = height

    def work_time(self, time):
        if time >= 8 and time <= 12:
            self.weight -= 2
        elif time > 12:
            self.weight -= 5
        else:
            pass
        return self.weight

    def judge_body(self):
        if self.heigh - 105 == self.weight:
            print("身材标准")
        elif self.heigh - 105 > self.weight:
            print("身材偏瘦")
        else:
            print("身材偏胖")

p1 = Man("Chen", 29,130,170)
wight = p1.work_time(13)
print(wight)
p1.judge_body()
