I've got a probably embarrassing trivial problem with namespaces, but couldn't solve it
myself nor find an answer in the net. Hopefully one of you guys can help me.
What I want to do:
Use the interactive shell and e.g define the variable a there.
Then load a module and access a from within.
e.g file "utest.py"
def doit():
print 2*a
in the shell:
import utest
a=3
utest.doit() <- I want this to print 2*a, but of course obtain: <type
exceptions.NameError'>: global name 'a' is not defined
Any change I do to a in the shell should be seen from the doit() function, any variable
assignment I do in the doit() function should be seen in the shell. I guess it's somehow a
namespace sharing.
Actually the function doit() will contain an eval() function that should evaluate a (via a
gui) dynamically inserted expression.
Any one got a clue? (a clue what I try to say and how to help?!)
Thanks a lot in advance!!
Ulrich
