Welcome back
 , I can tell you've spent too much time on other langauges! I guess you are trying to create a local variable and assign a list to it. showdata = [var1,var2] will do the trick Because of that little buglet the local variable has not been created so the compiler looks in the global scope to find out what showdata might be and can't find it. I suspect it does not even get as far as trying to figure out what showdata[var1,var2] would compute to Here is one possibility: Code:
>>> a = {}
>>> a[1,2]="test"
>>> a
{(1, 2): 'test'}
Where a tuple is the key! Grim

Code:
for c in range(len(showdata)):
print c, showdata[c]
Also, if you're using Python 2.3, the New Way(tm) of tidying up that range(len(x)) code is the 'enumerate' method, like so: Code:
for index, value in enumerate(showdata):
print index, value
