Sorry I meant key words )

better not to change the buildin keywords

I would rather not use buildin keyboards

Nice comment indeed. Thanks. I wish the variables were also more self explanatory.

Not readable.

could one please tell me about +c? Seems it converts string to int!

variable names can be improved a bit. well done.

Thank @Awesome A.D.. I did not know.

naming can be improved. The 'c' is not a good varaible name to me.

just else and one x.count are extra. Much better to call functoin once.

if else is extra

variable names are not good at all.

You cam make a method static by the @staticmethod decorator.
