(#2647722)
Use if not x instead of if x == 0 or if x == "" or if x == None or if x == False; likewise, if x instead of if x != 0, if x != None, etc.
Be careful with this one. "if not x" isn't necessarily the same as "if x == None". It's easy to forget that "if not x" will be true for values other than None.
Also, use "if x is None" rather than "if x == None". :-)
