Project requirements

Let’s attend to our client’s requirements for the project once again, this time focusing on the requirements highlighted in green for updating the score when the user answers a maths question correctly.

What if

We know we’ll only need == to check for the answer’s correctness. What if we had something in Python that could let us update the score, but only if the user_answer == correct_answer:

Python 3.10.4
score = 0
if user_answer == correct_answer:
    score = score + 1
else:
    print("Unfortunately your answer is not correct.")

Now, this code reads neatly. This is as easy as it looks—Python lets us use an if-else to control the flow of code execution.
