[Python-projects] Some false positives from pylint

[Marc 'BlackJack' Rintsch]

Hi *,

The `constant` naming regex flags functions as constants.  While they 
are constants to some degree, I don't think they should be written in 
all caps::

 def make_adder(add_value):
     def adder(num):
         return num + add_value
     return adder

 add5 = make_adder(5)

 def new_name():
     pass

 old_name_or_synonym = new_name

I guess it's not in the scope of pylint to recognize closures but maybe 
there's enough information available to get simple synonyms for 
``def``\ed functions?

I've used this extensivly to define functions that read metadata from 
multimedia files.  There's a default dummy function assigned to the 
function name first and then, depending on the availablity of external 
modules it may be rebound to a function that actually is able to read 
the metadata from a given filetype.

In the same program I get plenty of ``Instance of 'None' has no 'XYZ' 
member`` because I've initialized some variables with `None` 
first.  :-/

Another false alarm::

 item = None
 for item in xrange(5):
     pass
 print item

 item2 = None
 TEST = [item2 for item2 in xrange(5)]
 print item2

There's a ``Using possibly undefined loop variable 'item(2)'`` warning 
for both ``print`` statement lines.

Ciao,
