This code will help you understand the difference between class variable, instance variable and local variable.

class Test:
x = 10 //class variable or static variable; shared by all objects
def __init__(self):
    self.x = 20 //instance variable; different value for each object
def func(self, x): //method variable
    print Test.x
    print self.x
    print x

Output:
10
20
30
Test.x prints the static varible. To use instance variable you have to use self.instance_variable and you can directly use the local variable by its name inside the method.

You need to do as follows! As Barmar mentioned, it isnt a good practice to use the same name for class and class variable!

>>> class x():
...     def method(self, v1):
...             self.x = v1
...             print self.x
...
>>> y = x()
>>> y.method(5)
5
>>> y.x
5
