Consistently use "is" or "is not" to compare variables to None, because doing so is preferrable, as per PEP 8 (http://www.python.org/dev/peps/pep-0008/#programming-recommendations):

Comparisons to singletons like None should always be done with is or is not, never the equality operators. Signed-off-by: Claudio Bley <cbley@av-test.de>

Purely mechanical change, using:

find . -name '*.py' -exec sed -i -e 's,[ \t][ \t]*!=[ \t][ \t]*None, is not None,g' '{}' \+ find . -name '*.py' -exec sed -i -e 's,[ \t][ \t]*==[ \t][ \t]*None, is None,g' '{}' \+

This change makes sense. ACK Guannan
