False analysis, I'm afraid. The problem is that the assignment will,
in the absence of a "global" declaration, cause the name "count" to
indicate a local variable - so it won't ever be read from outer scope.
However, the OP's issue is better solved by sharing tracebacks than by
us peering into crystal balls; mine's showing a very clear image at
the moment, but it might well be incorrect.
