Not if this is all you are doing. A variable A in script1.py and a 
variable A in script2.py are completely different, even when running in 
the same thread.

But if you're running script1.py and script2.py by calling execfile or 
exec and you pass the same dictionary as the globals argument to 
execfile, then the two scripts would share the global namespace. 
Variables of the same name would really be the same variable.
