Hi,
I'm a newbie and was wondering which of these IF conditions is better structure:


1. if not os.path.exists('filename'):

I prefer the above.

   2. if os.path.exists('filename') == False:

They both work so if one preferred over the other?

Note that in Python in general, 'not x' and 'x == False' are not equivalent; 'not x' will be true for many more values than just False. For example
not 0
not 0.0
not []
not {}


are all True.
