如何在 Python 中声明静态属性？

这里写了如何声明一个方法：Python 中的静态方法？ https://stackoverflow.com/questions/735975/static-methods-in-python

Python 中类级别定义的所有变量都被视为静态

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)

您的类中可以有两个不同的同名变量（一个静态变量和一个普通变量）。 别混淆了。
