[Python-projects] pylint lambda bug

[Mark Flacy]

Greetings.

Running pylint over the attached file gives these results:

pylint -f parseable bug.py
bug.py:1: [C] Missing required attribute "__revision__"
bug.py:6: [E, buggy.<lambda>] Using variable 'a' before assignment
bug.py:6: [E, buggy.<lambda>] Using variable 'b' before assignment


I'm running...

/tmp$ pylint --version
pylint 0.12.1,
astng 0.16.1, common 0.19.2
Python 2.4.3 (#1, Oct  2 2006, 11:23:48)
[GCC 3.3.6]


The release notes in the mailing list stated that __revision__ was no longer required, so I am surprised to see that message.  The lambda error is from a lambda construct of...

lambda (a, b): a != b

...but if I were to change that bit of code to be...

lambda (x): x[0] != x[1]

...then pylint will be quiet about the lambda expression.

Thanks!
