Personalized tests by email with Pure Python

In the last post I showed you how to send different emails to different addresses with python. This time we are going a little further showing a practical example of a test with different data sent to different students and having the solution save in a file, so that we ca easily correct the different tests, without having to stress out too much having different solutions for each test. This is the code and it should be watched after seeing the last post.

The code to send the exercises

import smtplib
from credentials import *
from random import choice





# THE STUDENTS EMAILS

receivers = [
            "[email protected]",
            "[email protected]",
            "[email protected]"]

# RANDOM DATA FOR THE TEST

The credentials.py file

You need to create a file with your credentials. It is very easy. I explained this part here.

The file to make the text for the different tets

So, you need this second file. You do this. Copy the text for the array of tests into the previous one and you are good to go. In a next post I will make some more consistent code to make this work with just one script and, maybe, even with a grphic user interface, using tkinter. Until then, here is our code. Do not worry, it’s all explained in the video below, anyway.

from random import choice
import os

text = """
Create a balance sheet and income statement based on these data:

Operating costs {}
current assets {}
assets {}
taxes {}
revenues {}
financial charges {}
debts {}


Put the voices in the balance sheet and income statement.
Find the net assets and the economic result
