[Python-projects] is class inheritance supposed to be supported in pylint 0.14.0 ?

[Tim Black]

Here is a simplified example that exhibits the problem. 

 

Parent is the parent package to sub-packages A and B.

 

Sub-Package A:

Parent/A/__init__.py  contains "import a"

Parent/A/a.py contains:

 

from __future__ import absolute_import

from ..B import b

class aClass(b.bClass):

    def __init__(self):

        b.bClass.__init__(self) 

    def foo(self):

        print self.x

        print self.y

        print self.z

         

Sub-Package B:

Parent/B/__init__.py  contains "import b"

Parent/B/b.py contains:

 

class bClass:

    def __init__(self): 

        self.x = 0

        self.y = []

        self.z = ''

 

The Parent package is located in my sys.path. The above code runs just
fine:

 

>>> import Parent.A

>>> a = Parent.A.a.aClass(1)

>>> a.foo()

0

[]

 

However, when I run pylint for A/a.py it gives me 

 

F0401:  9: Unable to import 'B.b' (No module named B)

 

and therefore of course the ensuing errors:

 

E1101: 14:aClass.foo: Instance of 'aClass' has no 'x' member

E1101: 15:aClass.foo: Instance of 'aClass' has no 'y' member

E1101: 16:aClass.foo: Instance of 'aClass' has no 'z' member

 

If I change the import syntax in Parent/A/a.py to use "from Parent.B
import b" all errors go away. This seems to indicate a problem with
intra-sub-package relative imports. Any ideas?

 

Thanks,

Tim
