[Python-projects] * has no '__class__' member

[MATSUI Tetsushi]

Hello,

I found pylint complains about the __class__ attribute for many
built-in types.

Here is a dull example code runs without an error:

print (1).__class__
print (1L).__class__
print "1".__class__
print object.__class__
print object().__class__

class Empty (object):
    "an empty class"

print Empty.__class__
print Empty().__class__


The result of the above:

<type 'int'>
<type 'long'>
<type 'str'>
<type 'type'>
<type 'object'>
<type 'type'>
<class '__main__.Empty'>


pylint complains 5 times about __class__ out of 7:

E:  1: Instance of 'int' has no '__class__' member
E:  2: Instance of 'long' has no '__class__' member
E:  3: Instance of 'str' has no '__class__' member
E:  4: Class 'object' has no '__class__' member
E: 10: Class 'Empty' has no '__class__' member


I hope this behavior be fixed.


Only old style classes have no __class__ members as far as I tried.
For example:

class OldStyle:
    pass

OldStyle.__class__

fails with an AttributeError.


Thanks.
