Here is your problem. a is a name, bound to some value. So - it is true, 
as python semantics are that way. It would not be true if it was e.g.

False, [], {}, None, ""


What you want instead is something like

if event.source == a:
     ...

Please note that I don't know what event actually looks like in Tkinter, 
so check the docs what actually gets passed to you.
