Tkinter to send tests via email to stundents

In the last post (and also in this) we’ve seen how to create different tests for students with random data, so that all the tests are different, send them to the students with one run of the script, having also all the solutions saved in a text file, so that we can correct them easily. Now ve are going to add another feature. We use a tkinter window to see the ouput before we send them via email and having the chance to also change the output and then see the changes and finally decide to send the emails to the stundents with the new look.

Here is the code, followed by the live coding video o this code.

import smtplib
from random import choice
import os

# change the password as you see in the last post
password = "xxxxxxxxxxxxxxxxxxxx"

pss = {
    "dDApofsfdsflito": "010",
    "wGdiordsdfsasaano": "001",
    "fGuaafrisdfglia": "100",

    }


destinatari = [
    "[email protected]",
    "[email protected]",
    "[email protected]",
]


schema = """
Your code is {}

Write what is {} x {}

The exercise is here
https://formazione.github.io/Programmi20192020/text_5bs/quiz/risposta_email_02.html
"""
def new_schema(schema):
    numeri = [1, 3, 5, 7]
    messaggi = []
    soluzioni = []


    for s in pss:
        num1, num2 = choice(numeri), choice(numeri)
        traccia = schema.format(pss[s], num1, num2)
        messaggi.append(traccia)
        soluzioni.append(s + "\n" + traccia + "[S: " + str(num1 * num2) + "]\n\n")


    with open("soluzioni.txt", "w") as file:
        file.write("".join(soluzioni))
    print(*soluzioni)
    os.startfile("soluzioni.txt")




def manda_email():
    for n, mess in enumerate(messaggi):
        server = smtplib.SMTP("smtp.gmail.com", 587)
        server.ehlo()
        server.starttls()
        server.ehlo()
        server.login("[email protected]", password)
        server.sendmail(
            "[email protected]",
            destinatari[n],
            messaggi[n])
        server.quit()
