It depends on whether you want to have a class variable or an instance
variable; looking at the following variation of your code should make
clear the difference:

class myClass:
    f = [1, 2, 3]
        
    def showVars(self):
        print self.f


class myClass2:
    def __init__(self):
        self.f = ['a', 'b']
        
    def showVars(self):
        print self.f

            
print myClass.f

myc = myClass()
myClass.f = [4, 5, 6]
myc.showVars()

myc2 = myClass2()
myClass2.f = ['c', 'd']  # this f is created here!!!
print myClass2.f
myc2.showVars()


+++ OUTPUT +++

[1, 2, 3]
[4, 5, 6]
['c', 'd']
['a', 'b']


Remark: 'Normally', you want something like myClass2.
