Hi,
the following code does not work until I ommit the "a=0" statement.
def test():
exec "a=3" in locals()
print a
a=0
test()
print raises:
UnboundLocalError: local variable 'a' referenced before
assignment
Can anybody explain what is going wrong here ?

I'm trying to parallise with python. Specifically I'm sending code to
the processes and let them exec this code (in ascii form). However I
ran into a problem with Namespaces (I think) which I do not understand.
Here's what I do first:
---
bash-3.2$ cat execB
Dear python users!
I try to setted up compile-free parallelism using the exec command.
However I had some problems with namespaces which I find mysterious
although I managed to work around. But the workaround is not nice, so
I wonder if there are ways.
I do the following,
bash-3.2$ cat execB

Hello,
After my program read and translate this code:
koristi os,sys;
ispisi 'bok kaj ima';
into the:
import os,sys;
print 'bok kaj ima';
and when it run this code with "exec", I always get error like this, but I
still dont't know what is a problem:
Traceback (most recent call last):

I'm using code.Interactive console but it doesn't work correctly
with non-ascii characters. I think it boils down to this problem:
Python 2.4.3 (#69, Mar 29 2006, 17:35:34) [MSC v.1310 32 bit (Intel)] on win32
Type "help", "copyright", "credits" or "license" for more information.

Well... I *do* realize that. But this is *not* my problem. I have a
function with another nested one. If I used "exec ..."

I have the following code:

a = 'A' # marked line 2

That impression confuses two things:

I have the following little piece of code:
class Cfg:pass
#config = Cfg()
def assign():
setattr(config, 'Start' , [13, 26, 29, 34])
def foo():
config = Cfg()
dct = {'config':config, 'assign':assign}
exec "assign()" in dct
print config.Start
foo()
When I execute this I get the follow
40 matches
