if found is not None

means: if 'found' is not the same object as 'None'

(Toggle Plain Text)

if found != None

means: 'found' is not equal to 'None'

I am a total Python noob. That means ignorant, or uninformed; not stupid. Please do not mislead me while I'm trying to learn, whether it's to promote yourself as a guru, or high-priest, or for any other reason. If you care to give a rational dissertation on why one of the above is safer than the other (particularly in this circumstance), please feel free to do so. I'll certainly read it with all my attention.
