python static variable Variables declared inside the class definition, but not inside a method are class or static variables: >>>classMyClass:...i =3...>>>MyClass.i3 As @Daniel points out, this creates a class-level "i" variable, but this is distinct from any instance-level "i" vari...
Note python has this really weird error if you define local variable in a function same name as the global variable, program will promptUnboundLocalError. child class object overrides parent class methods input: classfruit:defprint(self):print('a')defeat(self):print('b')classapple(fruit):defpr...

If a name is bound in a block, it is a local variable of that block. If a name is bound at the module level, it is a global variable. (The variables of the module code block are local and global.) If a variable is used in a code block but not defined there, it is afree var...
In Python, a class variable is shared by all the object instances of the class. They are declared when the class is constructed and not in any of the methods of the class. Since in Python, these class variables are owned by the class itself, they are shared by all instances of that ...
