Parsing variables out of python lines

I hate finding answer quickly after posting. Anyway, here is code that will
solve my problem:
import tokenize
import StringIO
foo = [1,2,3]
x = "for i in foo:"
#
#The StringIO trick turns a string into a read'able object (or so it seems)
#
t = tokenize.generate_tokens(StringIO.StringIO(x).readline)
for junk, item, rest1, rest2, rest3 in t:
if item in vars():
print eval(item),
else:
print item,
print
With output:
==> for i in [1, 2, 3] :
Anyone know how to clean up the tuple assignment (I only want item, the rest
could go to /dev/null if they want).
Thanks anyways. Hope this is useful for someone else.
Regards,
Mark
