如何在Python中声明静态属性？

这里写了我如何声明一个方法：
Python中的静态方法？

Answer 1

在Python的类级别定义的所有变量均被视为静态

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)

在类中，您可以使用相同的名称拥有两个不同的变量（一个静态变量和一个普通变量）。不要困惑。
