Part 2: some working code for python, nltk, sql chatbox experiment

Update: 9-10-19 Life has been hectic, but I am constantly stirring this project in my brain pan.  I hope to do the part 3 soon, but it's a ton to learn.  I will come back to it when life gives me time.


I started to tackle this today, and if you haven't looked at part 1 of this experiment, and you want to it's mostly just me figuring out what I need to setup and psuedocode.  Here's the link:

I decided since my SQL skillz are very light and soft, The SQL part will need to be a part 3 while I take the time to learn more as I go.    For part 2 I have for you some working code.   I had some issues with the python enchant import, and it may have to be excluded from the experiment for the time being.  If all else faills I can run it on my Linux machine, but that may not be an option for you. None of these windows issues happen on my chatbot at the website because the server is SET UP for python.

I don't think enchant will be necessary as we are returning a default response for anything that isn't in the trigger words lists.  The txt file is just ten lines of things about me.

"She is a learner and a dreamer."
"There is sillyness but there is also seriousness."
"She is a Michigander through and through, a love of fresh water, and the smell of Fall."
"Art is also a passion, she paints and likes to do portraits."
"Although she didn't finish college, she is making another go at Montcalm Community College."
"Interesting factoid, Nellie was a registered working CNA for about 2 months."
"She made me, and I'm awesome, so is she."
"She's worked in jobs that most people would walk away from on their first day.  Many had."
"The machine at the paper mill she worked with broke numerous records for 'Days without a break'."
"My creator, Nellie, loves a good brain teaser. (Professor Layton(NDS) is great for puzzles!)."
"Her favorite way to decide to do something with code is to ask, 'Why not?' There is rarely a reason not to try something new."

I've added comments and such to the code. 
Here it is:

#  pyenchant would not install on my windows 10 machine, some C library was missing.  I found a solution on StackOverflow:
# https://stackoverflow.com/questions/29381919/importerror-the-enchant-c-library-was-not-found-please-install-it-via-your-o
#   install happened, but enchant is still not running because of missing Windows 10 C wheel for pyenchant.
# 'Art' is the user answer for: 
#   Resolved: On Win7-64 I ran
#   pip3 install pyenchant==1.6.6
#  python enchant removed from experiment.
