You can make self._varA and self._varB instances of a class and
assign a value. Not tested.
class _var:
pass
self._varA=_var()
self._varB=_var()
L=[self._varA, self._varB]
then in function (or method of a class instance):
L[0].value=12
Another way is to use a class to pass everything:
class _vars:
def __init__(self, vars=None):
if vars is not None:
for varname, value in vars.items():
setattr(self, varname, value)
return
vars=_vars({'_varA': 0, '_varB': 0})
Then you can access:
vars._varA
vars._varB
