I'm working on a Spanish app on Python. I created the quiz (def quizEtoS), which randomly selects one of the questions and set of answers from a string. I use the same buttons for all questions (A, B, C, D). However, I'm not quite sure how to create some sort of function so whenever the user selects the correct answer, another question pops up. Help is appreciated!

Answer 1

There are issues with the imports. You import everything from Tkinter and then tkinter as ttk, and finally everything from ttk. This gets confusing and differences in my Python setup may explain why I can't run your code.

I get an error originating from ttk but if I change the imports to only Tkinter it works ok.

Selecting random key

They've changed slightly how dictionaries work in Python 3, dict_keys no longer support indexing. You'll have to convert keys / values to list.

quizQs_keys = list(quizQs.keys())
qOne = random.choice(quizQs_keys)

More explanations

The first error I got was the:

TypeError: 'dict_keys' object does not support indexing

which had to do with Python 3 dicts.

After fixing that I get:

TypeError: 'dict' object is not callable

on the function:

def ansA():
    quizAs(btnA)

This is because you use parenthesis for the dict key when you should use square brackets. eg. quizAs[btnA].

Then I get:

KeyError: <tkinter.Button object .!button2>

because you are using btnA as key which is the reference to the top button. I guess that you would like to get the value with index of the correct answer, but then you must save the correct answer from the quizEtoS() function.

The back button works ok for me.
