Getting started with Thonny

Python Basics

• Comments start with # and help explain the code

  # This is a comment

• Print function displays a message/result in the shell

  print("Hello!")

• Input function displays a prompt, allows user to type

  name = input("Your name? ") print("Hello", name + "!") # adds exclamation point

Exercise 1: warmup.py

Write a program that...

1. Asks the user:

   • What is your name?
   • Where do you like to go?
   • What do you do there?

2. Outputs a sentence

Example:

What are your favorite stories?

Exercise 2: story.py

1. Copy the starter code, save as story.py
2. Run the program
3. Add more phrases
4. Repeat steps 2 and 3
   
   

Notice that each phrase:

• Is inside double quotes
• Has a comma at the end

Exercise 3: Text Wrapping

1. Add this line at the top:

   import textwrap

2. Replace print( with:

   story = " ".join([

3. Replace the ) with:

   ]) print(textwrap.fill(story, width=72))

Do you think AI could do better?

Let's make our own AI chatbot!

Install the chatterbot Library

1. Tools > Options > Interpreter > New virtual environment

   • Create a folder named venv, press Ok (twice)

2. Copy and run the "Installation Commands" on the website

Exercise 4: Your own conversation

1. Copy the starter code, save as chat.py
2. Run the program
3. Try having a conversation
   
   

An untrained ChatterBot starts off with no knowledge of how to communicate!

4. Add more example questions and answers
   • Edit the conversation under trainer.train
5. Repeat steps 2, 3 and 4
   
   

Exercise 5: Larger training data

1. Copy/paste the code on the website
2. Run the program
3. Try having a conversation
   
   

Optional: Feel free to try a different language!

Optional: See the chatterbot-corpus data files

Exercise 6: Explore the database

1. Find the file named db.sqlite3
   • Double click to open the file
2. Click the "Browse Data" tab
3. What surprises you about the data?
4. What potential problems do you see?
