[mcj]DigitalOcean使用SSH KEY进行连接(FinalShell篇)
每次都用一次性密码太麻烦了，这次我们选择使用SSH KEY进行连接，这种方法优点很多，安全性极高。 首先下载puttygen，然后： 生成之后，我们选择保存私钥和公钥，注意选择一个你不会忘记的地址，我选择的是“我的文档”，这个目录我基本都用 […]
[mcj]Python中使用双下划线对变量进行隐藏和封装
|
1 2 3 4 5 6 7 8 9 10 11 12 13 |
class User : def __hide(self): print('示范隐藏的hide方法') def setname(self, name): if len(name) < 3 or len(name) > 8: raise ValueError('用户名长度必须在3～8之间') self.__name = name def getname(self): return self.__name u = User() |
使用__双下划线可以将变量进行隐藏，这样我们就不能直接通过u.__hide()进行调用。 但是我们可以通过property函数进行调用： name = property(ge […]
[mcj]Python类实例化时带括号与不带括号的区别

1 2 3 4 |
class Dog: def __init__(self,name="doudou"): self.name1 = name fur = "black" |
带括号实例化，
|
1 2 3 |
d1 = Dog() print(d1.name1) #doudou |
不带括号实例化：
|
1 2 3 4 |
d1 = Dog d2 = d1() print(d2.name1) #doudou |
其实不带 […]
[mcj]Python中类、对象、方法、变量(类变量、实例变量)解释

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
class Dog: # 类 fur = "blue" # 变量 def __init__(self,name="doudou"): # 构造方法 self.name1 = name # self.fur = "black" def run(self): # 方法 self.jump() print("狗在跑") def jump(self): print(self.fur) self.fur = "red" d1 = Dog() # 对象 d1.color = "yanse" |
这其中，Dog就是我们定义的一个类，d1=Dog()就是实例化的一个对象。 run、jump是我们定义的方法，其中__init__也是一种方法，只不过这种方法比较特殊，被称为 […]
