See example:
>>> import argparse
>>> a = argparse.ArgumentParser()
>>> b = a.parse_args([])
>>> if b != None:
... print "hey"
File "<stdin>", line 2
print "hey"
^
SyntaxError: invalid syntax
>>>
>>> if b != None:
... print("hey")
...
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/cfd/software/Python/340/lib/python3.4/argparse.py", line 1202, in __ne__
return not (self == other)
File "/cfd/software/Python/340/lib/python3.4/argparse.py", line 1199, in __eq__
return vars(self) == vars(other)
TypeError: vars() argument must have __dict__ attribute

I believe this comes from doing vars(None). But why would this be happening if Namespace is empty. |

The equality and inequality tests need to return NotImplemented when comparing to an unknown type. |
