Do I always have to write "self." ?

It wouldn't be too hard to write a preprocessor that would do this
for you. You might put tags in your code such as
#Locals: foo bar xyzzy
so that the translation process for foo, bar, and xyzzy would be limited
to the method where they are used. If you promise yourself never to use
a 'def' inside a method definition, you could omit the '#Endlocals' tag,
and just look for the next line with the regular expression 'def ' in it.

The choice to use the word 'self' is not imposed by Python, it's just
a convention for readability. You can use 's' instead if you wish.
det = self.b ** 2 - 4 * self.a * self.c
return ((-self.b + math.sqrt(det)) / (2 * self.a),
(-self.b - math.sqrt(det)) / (2 * self.a))
det = s.b ** 2 - 4 * s.a * s.c
return ((-s.b + math.sqrt(det)) / (2 * s.a),
(-s.b - math.sqrt(det)) / (2 * s.a))
- - - - - - - - - - - - - - - - - - - - - - - -
Resistance is futile. Capacitance is efficacious.
