Instead of modifying the tuple (which you can't do), you can create a new
one:
a, b = myDict[key]
myDict[key] = (a+1, b)
It's a bit inefficient, but get it working first, with clear, easy to
understand code, then worry about how efficient it is.

But, classes are so lightweight in Python. You can get away with nothing
more than:
class Data:
pass
and then you can do things like:
myData = Data
myData.a = a
myData.b = b
More likely, I would want to write:
class Data:
def __init__ (self, a, b):
self.a = a
self.b = b
but I've done the minimilist Data class more than once. It doesn't cost
much, and it's often more self-documenting than just a tuple.
