推荐答案
Python中类级别定义的所有变量都被认为是静态的
All variables defined on the class level in Python are considered static
class Example: Variable = 2 # static variable print Example.Variable # prints 2 (static variable) # Access through an instance instance = Example() print instance.Variable # still 2 (ordinary variable) # Change within an instance instance.Variable = 3 #(ordinary variable) print instance.Variable # 3 (ordinary variable) print Example.Variable # 2 (static variable) # Change through Class Example.Variable = 5 #(static variable) print instance.Variable # 3 (ordinary variable) print Example.Variable # 5 (static variable)
您的类中可以有两个不同的变量在同一个名称下(一个是静态的,一个是普通的).不要混淆.
You can have two different variables in your class under the same name (one static and one ordinary). Don't be confused.
