[Python-Dev] FW: using globals

[Werkhoven J.P. van (Sjaak)]

> Hi,
> 
> I have got a problem with importing global variables. For instance I have
> got two files:
> 
> # t1.py							#t2.py
> 
> counter = 1				
> 
> def counter_adder(filenr):					def
> show_adder():
>    global counter						    import
> t1
>    counter+= 1
> print("adder is %d" % t1.counter)
>    if filenr == 1:
>       show_adder()
>    else:
>       import t2
>       t2.show_adder()
> 
> def show_adder():
>    print("adder is %d" % counter)
> 
> >>counter_adder(1)
> adder is 2
> >>counter_adder(2)
> adder is 1
> 
> When I look at the outcome of two function calls I expected no differences
> but much to my surprise it goes wrong when the global variable is
> imported. It doesn't give the updated value but the value it get when
> instantiated. Who come? What should I do to get the updated value
