python 對象的初始狀態(構造函數)

class Person(object):
    #name = "stu"
    #age = 10
    #height = 160
    #weight = 90
    def run(self):
        print("run")
    def eat(self, food):
        print("eat " + food)

    def __init__(self, name, age, height, weight):
        #print(name, age, height, weight)
        #定義屬性
        self.name = name
        self.age = age
        self.height = height
        self.weight = weight

'''
構造函數：__init__()   在使用類創建對象的時候自動調用
注意：如果不顯示的寫出構造函數，默認會自動添加一個空的構造函數

per = Person("hanmeimei", 20, 170, 55)
