Online Python classes in Mönchengladbach
Online can mean a video you watch alone at midnight, or a person who watches you type and stops you when the loop goes wrong. Ours is the second kind. This page shows what one live Python lesson looks like from the inside, the four stages a learner in Mönchengladbach moves through, how that sits next to Informatik at NRW schools, and a real project on the city's own energy data in which two dates in the same row tell two quite different stories.
Live teaching since 2020 · 10,000+ students worldwide · a real mentor on the call, in English
The short answer
Modern Age Coders runs online Python classes for Mönchengladbach as live video lessons taught in English: a mentor shares a screen with the learner, watches the code being typed and corrects it on the spot. Teenagers from about 13 and adults start with typed Python, move to files and real data, then build their own projects, either in a group of 15 to 20 or alone with a mentor who matches your pace and accent.
Where Mönchengladbach learners start
Three Python courses for Mönchengladbach
One full course for school pupils, one for adults and university students, and one for teenagers who already know a little Python and want to work with data.
What actually happens in a live online Python lesson?
Most people in Mönchengladbach who ask about online classes have tried a recorded course and stopped. The difference is a person who can see your screen.
The first ten minutes
The lesson opens on a video call. The mentor asks what happened with last week's exercise, and the learner shares their screen with the code still on it. If something did not run, that is where the lesson starts, because a mistake you made yourself teaches more than one in a slide.
Then the mentor sets the day's problem in plain English: one sentence, one goal, for example "count how many lines in this file mention solar".
The middle and the end
The learner types; the mentor watches. When a learner writes a loop that never stops, the mentor does not fix it for them. They ask what the loop is waiting for. In a group, the mentor moves between learners and shares the most useful mistake with everyone.
The last minutes are for a small task to finish before next time, written down in the chat so nobody has to remember it.

This comparison describes how Modern Age Coders teaches; it is our own summary, not a survey. Lessons are live online, given in English by India-based mentors, to groups of 15 to 20 or to one learner.
Because everything is on video, nothing about the lesson depends on where in Mönchengladbach you live, whether that is Rheydt, Wickrath or the Gladbach side of town, and nothing depends on a bus. What it does depend on is a laptop or desktop with a keyboard and a stable connection. A tablet will do for the first week, but typed Python is far easier with real keys.
Taught in English
Are the classes in German or in English?
English only, and we would rather you know that before the first class than after it.
English, said plainly
Every lesson is taught in English by mentors based in India. We do not run German-language Python classes. If you need the teacher to explain in German, we are the wrong choice, and we say so.
Your pace, your accent
Mentors slow down, rephrase and repeat, and they get used to the way you speak. A learner who answers in short sentences, or reaches for a German word, is understood and given the English one without fuss.
Python is already English
Keywords such as if, for, while, print and return are English words. Error messages are English too. Learning Python in English means the words on the screen and the words in the lesson are the same.
For pupils at a German school this has a second use: an hour of technical English each week, spoken rather than read. For adults in Mönchengladbach who work for international companies around Düsseldorf, English is often the language their code will be reviewed in anyway.
The Python path
How do you go from no Python to real projects?
Four stages, each one ending with something the learner has built and can explain. The times are typical, not promises; some move faster, some take longer, and both are fine.
Stage 1: talking to the computer. print, variables, input, if and else. The first program asks your name and answers back. By the end, a small quiz that keeps score.
Stage 2: repeating and deciding. for and while loops, lists, functions. Learners write a times-table tester and a guessing game, then learn to read an error message line by line instead of panicking.
Stage 3: files and real data. Opening a CSV file, reading it row by row, counting with a dictionary, sorting. This is where the Mönchengladbach solar project below sits.
Stage 4: your own project. The learner chooses a question, finds or makes the data, writes the program, and explains the answer and its limits to the mentor as if presenting it.

School in NRW
How does this fit with Informatik at NRW schools?
NRW now teaches Informatik to every pupil early on, then lets it become optional. A private Python class works alongside that, never instead of it.
Grades 5 and 6, then choice
The Gesellschaft für Informatik records in its Informatik-Monitor 2026/27 that every general school type in Nordrhein-Westfalen teaches the compulsory subject Informatik in grades 5 and 6: "An allen allgemeinbildenden Schularten wird das Pflichtfach Informatik in den Jahrgangsstufen 5 und 6 unterrichtet."
After that, at a Gymnasium on the nine-year route, Informatik is one of the subjects pupils can choose in the Wahlpflicht area of grades 9 and 10.
The Oberstufe and the Abitur
In the Qualifikationsphase, NRW offers Informatik as a three-hour Grundkurs or a five-hour Leistungskurs, according to the same monitor. The written Abitur tasks are set centrally, and the monitor notes that no computer is used to answer them.
So a pupil can write excellent Python and still need to practise writing and tracing code on paper for the exam. We help with both, and the school course is the one that counts for the grade.

A real Mönchengladbach project
The solar register: which date answers your question?
Mönchengladbach's open data portal publishes the city's part of the Marktstammdatenregister, the national register of power and gas units, under a licence that allows reuse with attribution. Our Stage 3 learners use it to learn a habit that saves professionals from embarrassing charts.
The data
The city's copy has 18,864 rows, every one in Mönchengladbach. In our count, 12,277 are solar units (energietrager "Solare Strahlungsenergie"), 6,413 are battery storage units and 14 are wind turbines. The register's own description calls it "das zentrale amtliche Register für Strom- und Gasanlagen in Deutschland" and says operators are legally obliged to register.
Each row has two dates that look alike: inbetriebnahmedatum, the day the unit was switched on, and registrierungsdatum, the day it was entered in the register.
The question
How fast did solar grow in Mönchengladbach? A learner who picks the first date column they see might get one answer; a learner who picks the other gets a very different one.
The learner's file, mg_energy_units.csv, is the city's export as downloaded on 3 November 2026. The first program counts solar units per year by both dates side by side.
Version 1: count by both datesPython
import csv
started, registered = {}, {}
with open("mg_energy_units.csv", encoding="utf-8-sig") as f:
for row in csv.DictReader(f, delimiter=";"):
if row["energietrager"] != "Solare Strahlungsenergie":
continue
start = row["inbetriebnahmedatum_der_einheit"][:4]
signed_up = row["registrierungsdatum_der_einheit"][:4]
started[start] = started.get(start, 0) + 1
registered[signed_up] = registered.get(signed_up, 0) + 1
for year in ("2010", "2018", "2019", "2023", "2025"):
print(year, " switched on:", started.get(year, 0), " registered:", registered.get(year, 0))
It prints: 2010 switched on: 207 registered: 0, 2018 switched on: 87 registered: 0, 2019 switched on: 138 registered: 377, 2023 switched on: 2345 registered: 2237 and 2025 switched on: 2366 registered: 2402.
By registration date, Mönchengladbach had no solar at all in 2010 or 2018. That is obviously false: 207 units were switched on in 2010 alone. The register simply did not take entries before 2019, so every older unit was entered later, in a rush. In 2020, 302 solar units were switched on, but 1,506 were registered. A chart by registration date would show a spurious solar boom in 2020; a chart by switch-on date shows the real growth.
Version 2: check the story before you chart itPython
older = sum(n for year, n in started.items() if year != "" and year < "2019")
print("Solar units switched on before 2019:", older)
print("Units with no switch-on date yet:", started.get("", 0))
print("First registration year in the file:", min(registered))
running = 0
for year in sorted(y for y in started if y != ""):
running += started[year]
if year in ("2018", "2022", "2025"):
print("Switched on by the end of", year, ":", running)
It prints: Solar units switched on before 2019: 1634, Units with no switch-on date yet: 156, First registration year in the file: 2019, Switched on by the end of 2018 : 1634, Switched on by the end of 2022 : 3242 and Switched on by the end of 2025 : 10420.

Data: Stadt Mönchengladbach open data portal, dataset Marktstammdatenregister (publisher Bundesnetzagentur, Marktstammdatenregister), licence Datenlizenz Deutschland Namensnennung 2.0, downloaded 3 November 2026. Counts are ours, solar units only, all operating states included. The 156 units with no switch-on date are listed as In Planung.
The answer the data supports is this: 1,634 solar units were running in Mönchengladbach by the end of 2018, 3,242 by the end of 2022 and 10,420 by the end of 2025, so more than two thirds of today's units were switched on in the last three full years. Since 2023 the two columns move together, because new units are registered when they are installed. The lesson is not about solar. It is that a column name is a promise you have to check: before you count, ask which event the date records.
Warm up. Run Version 1 and write one sentence about 2010 that is true and one that is false.
Your turn. Change the program to count battery storage units ("Speicher") instead. In which year does the first one appear by each date?
Stretch. Find units whose registration year is more than five years after their switch-on year. How many are there?
Explain it. Write three sentences for a newspaper reader on why the 2020 registration figure is not a boom.
Class times
When are the classes in Mönchengladbach time?
The mentors teach from India, so a Mönchengladbach afternoon or evening lands in their evening. The rows below are examples to show the gap, not timetabled batches.

Clock rules: the Einheitenzeitgesetz fixes MEZ at UTC+1 in winter and MESZ at UTC+2 in summer. In 2026 the clocks went back on 25 October; in 2027 they go forward on 28 March. India stays on UTC+5:30 with no clock change, which puts it four and a half hours ahead of Mönchengladbach from late October to late March, and three and a half hours ahead the rest of the year.
You pick a slot in your own clock when you book, and the mentor sees it in theirs. Pupils often take the late afternoon after school; working adults tend to prefer a weekday evening or a Saturday morning. NRW school holidays do not stop the classes, though many learners pause for a family trip and pick up again afterwards.
Progress you can check
What can a Mönchengladbach learner do after each stage?
Our own checkpoints. The mentor uses them to place a new learner and to tell you honestly how things are going.
Python checkpoints (ours)
Checkpoint
Typical point
The learner can
A. First program
Week 1
Run a script, print text, store and change a variable
B. Decisions
Weeks 2 to 5
Use if, elif and else to react to input
C. Loops and lists
Weeks 5 to 12
Repeat work, keep a list and write a function
D. Files
Weeks 12 to 20
Read a CSV file and count with a dictionary
E. Judgement
Weeks 20 onward
Say which column answers a question, and why
For parents of pupils
Checkpoint E is the one the solar project trains. It is also the skill a teacher looks for when a pupil explains code on paper in an exam.
You will hear what was built and what was hard, not how many minutes were spent online.
For adult learners
Most adults reach checkpoint D in about four months of two lessons a week. That is the point where Python starts saving time at work.
If a week is lost to work or family, the mentor picks up where you are, not where the plan said you should be.

Mönchengladbach asks
Online Python classes in Mönchengladbach: questions
Are the classes in German?
No, never: our Python lessons are held live in English, and only in English, by mentors who work from India. They slow down, adjust to your accent and say things a second way when the first one did not land. Since Python keywords are English words, lesson and code share one language.
Is an online Python class just a video?
Not with us. Each lesson is a live video call with a mentor who sees your shared screen while you type, asks questions and corrects mistakes as they happen. Nothing is pre-recorded, and the homework is checked in the next lesson.
Do I need to know any programming first?
No. Stage 1 starts with print and variables. If you already know some Python, the free first class is used to find the right starting stage so you do not repeat what you know.
What computer do I need?
A laptop or desktop with a keyboard, a webcam or at least a microphone, and a stable internet connection. Python and the editor are free, and the mentor helps you install them in the first lesson.
When are the classes?
Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays. Pupils often choose late afternoons, and adults often choose weekday evenings or Saturday mornings in Mönchengladbach time.
Does this replace Informatik at school?
No. In NRW every pupil has Informatik in grades 5 and 6, and later it can be chosen as a Grundkurs or Leistungskurs. We teach alongside school; the school course is the one that counts for grades and the Abitur.
Can adults join, or is it only for pupils?
Adults are welcome. The Python Masterclass is built for adults, apprentices and university students, and one-to-one plans let you learn around shifts or family. Many adults learn Python to automate work with files and spreadsheets.
How many people are in a group?
A group holds 15 to 20 learners who are at roughly the same stage. Anyone who prefers undivided attention can take the one-to-one plan instead: two private lessons each week, at slots agreed with the mentor.
Which currency will I be charged in?
In US dollars. The fees section displays each monthly plan in euro, converted with the ECB reference rate, so you can compare it easily; your card is then charged in dollars and your own bank turns that into euro, which can move the final figure by a little. Lesson one costs nothing.
What is the solar register project on this page?
An original project of ours on the Marktstammdatenregister data published by Stadt Mönchengladbach. Learners count 12,277 solar units by switch-on date and by registration date and find that registration only began in 2019, so the dates tell different stories.
