Thank you all for your replies, first of all my Sum function was an example simplifying what I have to do in my real funciton. In general the D dictionary is complex, with a lot of keys, so I was searching for a quick method to access all the variables in it without doing the explicit creation:
a, b, c = D['a'], D['b'], D['c'] and without using directly the D dictionary (boring...). When I talked about nested function I meant both cases Chris, but this is not a really tighten bound. I tried to follow the hints of Chris together with some help by google and used the following code: for k in D : exec "%s = D[k]" %k That seems to do the trick, but someone speaks about "dirty code", can anyone point me out which problems this can generate? Again, thank you for your help! -- http://mail.python.org/mailman/listinfo/python-list
