ChatterBotV2.1 coded in python

Question

I'm new to python and PEP 8, so I want to see how to improve my work. This is my first big project without a guide. This is 184 lines. I think I murdered PEP 8 and need help fixing that.

• GameDungeon: Someone already pointed out how to improve the rock paper scissors.codereview.stackexchange.com/questions/213738/…
• Peilonrayz: I'd suggest replacing the RPS code here with your improved code.
• GameDungeon: I'm having trouble adding the rock, paper scissors fix to my code.
• 200_success: @Peilonrayz I'm not the one who voted to close as "not working", but I see that asking for suggestions about what to add next is asking for advice about code that has not yet been implemented, and that would be problematic for Code Review.
• GameDungeon: I fixed that and see your point @200_success.

Answer 1

Some suggestions:

1. When I copy/paste the code into a file locally, I have problems with Python reading the source encoding. You didn't specify an encoding, and your joke text is full of non-ascii characters.

   I'd suggest that you store your jokes in a separate file, and read in that file either at startup or each time the joke function is called.

2. You have to ask the user's name in two places: during startup, and when changing the name in the settings. Therefore, you need a get_name() function to be called both places.

3. I'm not sure what the restart operation is about. But Python uses None to indicate no value, so that might be better than settings things to "Null".

4. Your math function is bad. Write an expression parser instead. ;-)

5. Don't catch Exception. It's a bad practice. Catch the specific error you intend to handle.

6. You have a bunch of bare code at the bottom of the file. Organize that into a main routine, and then do:

   if __name__ == '__main__':
    main()
   

   Doing this will allow you to import the module without going into the chatterbot directly, which means you can write unit tests for the various parts of the system.
