Add a Python tutorial to explain modules/imports

[IsaacOldwood]

I would like to add a new tutorial to the Python section about modules. I think there are a lot of great python tutorials that could be written but sticking within the keywords limits us. By adding a tutorial to explain modules, imports etc this allows us to write more complex tutorials using these tools.

For example, I would like to write a module about testing in Python. But this requires importing unittest or even installing pytest to do properly. So I think a pre-requisite workshop explaining how that works is the best next small step we can take. Happy to discuss further details in the thread, or I can put something together and we can review

Workshop design idea - Maths game: Beat the clock

Objectives - "In this tutorial we are going to look at modules and importing code from other files"
Goals - "By the end of this tutorial you will have a maths game that uses code from other files and asks the user for their input"

In lesson 1 you learnt how to save code to a file and then run that file - see Tutorial 1 Saving Your Work

Step 1

We will start today's lesson by creating a new file called level1.py, this contains a maths question for the player to answer. First level so 5 + 6 will do
print("What is 5 + 6?")
run the file using the cmd
python level1.py
See output

This isn't much of a game, the player needs to be able to give their answer, to do this we use the input function.

Change the line to input("What is 5 + 6? ")
The user can now type an answer and hit enter to submit it!
Now we can assign it to a variable and check it's the right answer
If it's right, print("Correct, move on to the next level")
etc....

Step 2

Introduce level2.py. Same idea, harder question.
Now we need to use the print("Correct, move on to the next level") from the other file to avoid duplication.
Teach about imports

Step 3

We can import built-ins too! Let's make the game harder by adding a timer.
import time
Check how long it takes to answer, if too slow then reject, otherwise print success message etc

BONUS

Check out the Python docs to find all sorts of useful functions to use!

Notes: This is the product of a short dog walk mulling this over so I'm happy to take a different direction. Also happy to scrap it completely if there is something else that's better - I'm not precious!
