In this Python tutorial, I will help you learn how to create a Quiz application using Python Tkinter. A quiz app helps test user knowledge through multiple-choice questions. We’ll create an interactive GUI where users can select answers with the click of a button. The app will track correct responses and calculate the score at the end.
Let’ get in.
Python Tkinter Quiz Application Code Description
In the below code, we have created a constructor that holds the values like the number of questions, the title of the window, questions with multiple options using the radio button, functions, etc.
This constructor will be called every time the program is run, so we have provided all the primary function names here.
class Quiz:
def __init__(self):
self.qno=0
self.disp_title()
self.disp_ques()
self.opt_sel=IntVar()
self.opts=self.radio_buttons()
self.disp_opt()
self.buttons()
self.total_size=len(question)
self.correct=0def disp_res() function is created to display the result of the quiz. The final result will be displayed using a message box in Python Tkinter. Wrong answers = total questions – total correct answers, and the final score in percentage would be score = (correct answers / total questions) times 100
def disp_res(self):
wrong_count = self.total_size - self.correct
correct = f"Correct: {self.correct}"
wrong = f"Wrong: {wrong_count}"
score = int(self.correct / self.total_size * 100)
result = f"Score: {score}%"
mb.showinfo("Result", f"{result}\n{correct}\n{wrong}")check_ans() function is used here to return the correct answers. The function compares the user-selected option with the correct option. If both are the same, then the function returns True.
def check_ans(self, qno):
if self.opt_sel.get() == answer[qno]:
return Truenext_btn() function is used here to move to the next question. Clicking on the ‘next’ button will display a new question. If no questions are remaining, then it will display the result.
def next_btn(self):
if self.check_ans(self.qno):
self.correct += 1
self.qno += 1
if self.qno==self.total_size:
self.disp_res()
ws.destroy()
else:
self.disp_ques()
self.disp_opt()There are two buttons used in the program:
- next_button: displays the result or a new question
- quit_button: Terminates the program.
def buttons(self):
next_button = Button(
ws,
text="Next",
command=self.next_btn,
width=10,
bg="#F2780C",
fg="white",
font=("ariel",16,"bold")
)
next_button.place(x=350,y=380)
quit_button = Button(
ws,
text="Quit",
command=ws.destroy,
width=5,
bg="black",
fg="white",
font=("ariel",16," bold")
)
quit_button.place(x=700,y=50)disp_opt() function is used here to display the options to the users for every question. These options are being fetched from the hard-coded database that holds the questionnaires, options, and their answers.
def disp_opt(self):
val=0
self.opt_sel.set(0)
for option in options[self.qno]:
self.opts[val]['text']=option
val+=1Object-oriented programming is followed in this source code so that we don’t have to repeat the code. Click here to download the data file that contains questions, options, and answers for the quiz.
