In short

Python does the work, you call the shots

The Believemy Python Accelerator is a 100-hour online course over 12 weeks. You learn to write your own programs to automate your work, up to the Tosa certification (RS6962).

  • Who it is for

    Solopreneurs, employees and complete beginners. No prerequisites: a placement test adapts the path to your level.

  • How it works

    9 modules, 11 projects reviewed on video and 25 quizzes, at your own pace. Your trainer checks in with you every week.

  • At the end

    The Tosa Python certification (RS6962), awarded by Isograd from 551 points out of 1,000. The exam is included in the price.

Believemy is a Qualiopi-certified training organization based in Paris.

What you will automate

You run the whole business alone. Python can take part of the load.

Every week, the same tasks eat hours of your time. Here is what you will hand over to your own programs by the end of the course.

Today

Every Monday, you look up who has not paid and write the reminders one by one.

With Python

On Monday morning, the script finds the overdue invoices and sends the reminders on its own.

reminders.py
import smtplib, datetime
 
if datetime.date.today().weekday() == 0:
for client in overdue_clients():
send_reminder(client)

You learn it in module 8 · smtplib

The syllabus

Nine modules, from your first line to a finished program

100 hours, in the order you take them. New sessions open every Monday, and each major part ends with a graded quiz.

  1. You set up your work environment and write your first lines of code in the very first hour: variables, data types, user input. An orientation step adapts the rest to your level.

    In practice

    5 hours of exercises on variables and types.

Your follow-up

Your trainer follows your progress, week after week

People who learn alone tend to give up. Here, someone follows your progress and gets you unstuck.

  • A check-in every week. Your trainer looks at where you stand and what is holding you back.
  • A video call whenever you need one. You book it from your dashboard, and your trainer offers one if your progress slows down.
  • Your questions between calls. Under each course session, by email or on the learners' Discord.
  • A video review of every project. You compare your solution and fill the gaps.
  • Support for up to 18 months. Beyond the 12 weeks, your trainer is still there.
