From the point of view of space research class
Where to add object properties
- You can add the class ______init______
class Human:
mind = "有思想的"
def __init__(self, name, age):
self.name = name
self.age = age
def eat(self,argv):
print("吃饭")
sun = Human("孙宇", 18)
print(sun.__dict__)- May be added in the process of class
class Human:
mind = "有思想的"
def __init__(self, name, age):
self.name = name
self.age = age
def eat(self):
self.habby = "女"
print("吃饭")
sun = Human("孙宇", 18)
sun.eat()
print(sun.__dict__)- Outside the class can also add
class Human:
mind = "有思想的"
def __init__(self, name, age):
self.name = name
self.age = age
def eat(self, argv):
print("吃饭")
sun = Human("孙宇", 18)
sun.sex = "男"
print(sun.__dict__)Where to add the class attribute
- Inner class
class Human:
mind = "有思想的"
def __init__(self, name, age):
self.name = name
self.age = age
def eat(self, argv):
Human.body = argv
print("吃饭")
sun.eat("大脸")
print(Human.__dict__)- Outside the class
class Human:
mind = "有思想的"
def __init__(self, name, age):
self.name = name
self.age = age
def eat(self, argv):
print("吃饭")
Human.lunguage = "中文"
print(Human.__dict__)The relationship between object space and class space
Space and space objects class have the same name, the object is certainly first look in the object space
Find the order:
Object Name: Object class space object pointer ---> class space ---> parent space
The name of the class name: class space ---> parent space
class Human:
mind = "有思想的"
def __init__(self, name, age):
self.name = name
self.age = age
def eat(self, argv):
print("吃饭")
sun.mind = "无脑"
print(sun.mind) # 无脑
print(Human.mind) # 有思想的The relationship between class and class
Dependencies: The main points from
The class name of a class or an object of another class incoming Method
class Elephant:
def __init__(self, name):
self.name = name
def open(self, obj):
print(f"{self.name} 默念三声：3，2，1 开门")
obj.be_open()
def close(self, obj):
print(f"{self.name} 默念三声“3，2，1 关门")
obj.be_close()
class Refrigerator:
def __init__(self, name):
self.name = name
def be_open(self):
print(f"{self.name} 冰箱 被打开了")
def be_close(self):
print(f"{self.name} 冰箱 被关闭了")
qiqi = Elephant("qiqi")
haier = Refrigerator("haier")
qiqi.open(haier) # 主.方法(从)
qiqi.close(haier)
# qiqi 默念三声：3，2，1 开门
# haier 冰箱 被打开了
# qiqi 默念三声“3，2，1 关门
# haier 冰箱 被关闭了connection relation
And a combination of similar
class Boy:
def __init__(self, name, girlfriend=None):
self.name = name
self.girlfriend = girlfriend
def have_a_diner(self):
if self.girlfriend:
print(f"{self.name}请他的{self.girlfriend.age}岁的，{self.girlfriend.body}女朋友{self.girlfriend.name}一起吃烛光晚餐")
else:
print("吃啥吃")
class Girl:
def __init__(self, name, age, body):
self.name = name
self.age = age
self.body = body
def skill(self,obj):
print(f"{obj.name}的女朋友{self.name} 会用萝莉音直播")
yec = Boy("叶尘")
qiao = Girl("乔碧萝", 53, "小钢炮")
yec.girlfriend = qiao
yec.have_a_diner()
yec.girlfriend.skill(yec)
# qiao = Girl("乔碧萝", 53, "小钢炮")
# yec = Boy("叶尘", qiao)
# yec.have_a_diner()
# yec.girlfriend.skill(yec)Combination of relationship
Combination: a class object is encapsulated into another attribute of the object class, called combination.
