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.
Oops. 0 and 0.0 do == False.
