>=3B Playing aroun= d=2C I've been trying to figure out the most pythonic way
>=3B of incr= ementing multiple values based on the return of a function.
>=3B Somet= hing like
>=3B
>=3B def calculate(params):
>=3B a =3D= b =3D 0
>=3B if some_calculation(params):
>=3B a +=3D = 1
>=3B if other_calculation(params):
>=3B b +=3D 1
&= gt=3B return (a=2C b)
>=3B
>=3B alpha =3D beta =3D 0
&g= t=3B temp_a=2C temp_b =3D calculate(...)
>=3B alpha +=3D temp_a>=3B beta +=3D temp_b
>=3B
>=3B Is there a better way to do= this without holding each temporary
>=3B result before using it to in= crement?
>=3B
>=3B -tkc
