[Python-projects] False warnings from 0.7.0 to 0.8.0
date
Updating pylint from 0.7.0 to 0.8.0 generates a lot of false warnings.2005/10/22 15:39
Generator expressions
=====================
# E0601 - Using variable 's' before assignment
major, minor = (int(s) for s in value.split("."))
# E0601 - Using variable 'validType' before assignment
typeList = ", ".join(validType.__name__ for validType in validTypes)
Packages split in multiple directories (using __path__)
=======================================================
I also get now a lot of E0611 warnings for "special" modules.
I have a few packages which don't have all their modules inside the
same folder. I modify the __path__ variable of the parent package so
that Python can find them. Unfortunatly pylint doesn't take this into
account right now. See http://www.python.org/doc/essays/packages.html
pylint doesn't recognize the __path__ package magic
===================================================
# package/__init__.py
# E0602 - Undefined variable '__path__'
__path__ += "folder"
# test.py
import package
Other package false errors
==========================
# AudioTime/__init__.py
class AudioTime(object):
DECIMAL = 3
# AudioTime/AudioTime.py
class AudioTime(object):
pass
# AudioTime/AudioTimeDecimal.py
from AudioTime.AudioTime import AudioTime
class AudioTimeDecimal(AudioTime):
pass
# test.py
from AudioTime import AudioTime
# E0611 - No name 'DECIMAL' in module 'AudioTime.AudioTime'
print AudioTime.DECIMAL
As you can see, the AudioTime class from AudioTime/__init__.py should
be given precedence over the AudioTime/AudioTime.py module just as
Python does.
Troubles with variables defined in parent class
===============================================
class Base(object):
def __init__(self):
self._var = False
class Derived(Base):
def Work(self):
# E0203 - Access to member '_var' before its definition line 13
if self._var:
print "True"
else:
print "False"
self._var = True
x = Derived()
x.Work()
