Quiz Game using Tkinter in Python

Question

I have made part of a quiz game and realize that if I continue down this route my code could get huge, is there a way to simplify my code or make it more efficient? The first couple of lines of MathsQuestions.txt are:

1.Work out the value of 3 × 8? a)12, b)14, c)16, d)18,
2.Work out the value of 4 × 2? a) 6, b) 8, c)12, d)14,
3.Work out the value of 8 × 2? a) 6, b)12, c)14, d)16,

Answer 1

Sure there are lots of ways to improve it! Let's begin with the small stuff and work our way up:

Undefined "score"

Either define it and then print it everywhere if you want, or just remove it. I removed it below.

General style

Have a look at PEP 8 for a good start on Python code style. Use vertical spacing, separate comment text from the hash, no spaces in keyword arguments, name functions in snake case, that kind of stuff.

Imports

Discard the ones you don't use, and generally try to avoid star imports, because that can lead to name clashes and confusion. Let's just use a single import:

import tkinter as tk

The big payoff: don't repeat yourself

Keep it DRY. When you see similar code twice, think about ways to write it only once. If you see it three times, you should definitely try to do something about that. Ten times? Boy oh boy. Fight that CTRL+C/CTRL+V instinct.

By parameterising the frame creation as follows, we can drastically reduce the complexity of creating multiple question frames.

    def __init__(self, master, r, q, a, q_number, q_text, switch_to):

        btn.grid(row=3, column=3)
        for i in range(3):
            btn = tk.Button(
                self,
                text=MathsQ[a],
                font=("Verdana", 35, "bold"),
                height=1,
                width=15,
                command=lambda: self.master.switch_frame(switch_to)
            )
            btn.grid(row=r, column=3)
            r = r + 1
            a = a + 1
        lbl = tk.Label(self, text="Maths Category", font=("Verdana", 25))
        lbl.grid(row=0, column=5, sticky="ne")

Now creating frames is as easy as 1-2-3.

This should pretty much achieve the exact same functionality, but as we can see the question number stays the same across most questions. You should probably have it running from 1 to 10. You should also be able to abstract it some more yourself, maybe by extracting the font styles or creating and placing labels, but this is a start. Indeed I think the switch_to argument is not needed if you just pass the correct question number and use it as an index. And looks like the indices to MathsQ and q and a have patterns (q = 5i, a = 5i + 2, qt = 5i + 1), so they could be just calculated instead of inputting them by hand.

Here's the final code dump just for completeness, but try changing the code yourself! Because the question and picture files were not provided, I can't promise this will run 100 %, but it should be ok at least with some debugging.
