Description Todd 2013-01-28 13:17:46 UTC
When trying to unpack nested tuples, kdev-python says the inner variables are undefined.  

Here is a simple example:

    a,(b,c)=(1,(2,3))

In this case you get "undefined variable: b" and  "undefined variable: c" problems

Here is a more practical example (mydict is a dictionary):

    for i,(key,value) in enumerate(mydict.iteritems()):
        pass

In this case you get "undefined variable: key" and "undefined variable: value" problems.

Both sets of code are valid in python 2 and python 3.

Yeah, valid bug -- I did not implement it so far since it seemed a bit complicated to do correctly. I'll put it onto the todo list. ;)

Fixed in python3, not going to backport it to python2 though.
