Python-Object-oriented Programming basics (Advanced)

Normal fields and static fields in a class

classfoo (): C_name='cc'    def __init__(self,content): Self.content=contentdefShow (self):Print(self.content)Print(foo.c_name) obj= Foo ('Test Content') obj.show ()Print(Obj.c_name)#Test Content#cc#cc

In this code, C_name is the static field in the class, and when you instantiate Foo, the ' test content ' is the normal field .

A static field is already in memory before the class is instantiated, and he is the Python interpreter that has run C_name = ' cc ' When executed from top to bottom.
