Python statement issue

I am trying to create a question/answer program where the program asks a question from a file and then compares the answer but when I write the right one it still tells that its wrong.

import random

def Questionnaire():  
    a=1
    i=1
    while i <= 10 :
        with open("mcq.txt", "r") as r:
            list = r.readlines()
            questions = random.choice(list)
            questans = questions.split(";;")
            question, answer = questans[0], questans[1]
            print(f"Q{a} - {question}")
            a,i=a+1,i+1
            ans(answer) 

def ans(answer):
    mychoice =str(input("What is your answer ?"))
    if mychoice != answer :
        print(f"Wrong answer, the right one is : {answer} \n")
    else :
        print("Bravo, it is the right one ! \n")

Questionnaire()

Here in my second function, the if else statement returns always False, even when I changed to make !=

>Solution :

Fix

The is because, when using readlines() it gives your a list of string ending by \n char, so the answer string becomes A\n that is different of A. Also sometimes there is a space before answer letter. Use str.strip() to remove both

question, answer = questans[0], questans[1].strip()

Improve

• you open and read the whole file at each iteration : read once at beginning
• random.choice could give the same row at 2 different iteration : use random.shuffle to randomize once, then take in order
• a and i does same, keep one
• use enumerate and a slice of your question list to do only X question

def Questionnaire(nb_question=10):
    with open("test.txt", "r", encoding="utf-8") as r:
        values = r.read().splitlines()  # don't keep ending \n

    random.shuffle(values)  # randomize once

    for i, questions in enumerate(values[:nb_question], start=1):
        question, answer = questions.split(";;")
        print(f"Q{i} - {question.strip()}")
        ans(answer.strip())
