In short In Osnabrück, Modern Age Coders teaches Python online in live video lessons held in English. Learners write the code on their own machines; one regular mentor in India follows the shared screen, asks questions and fits pace and accent to them. Pupils from about ten start with Maths through Coding or Python for Teens; adults take the Python Masterclass or Python web development. Classes run for fifteen to twenty learners, or one to one. Three Python courses ## Which Python course suits an Osnabrück learner? One for a pupil who likes maths, one for a teenager who wants the whole language, and one for an adult who wants Python that talks to the web. [![Maths Through Coding course thumbnail](/images/maths-through-coding.webp) POS / 01 Maths Through Coding Ten to fifteen. School maths, from fractions to functions, explored in Python, so a pupil learns both at once and sees why each formula works.

Five questions, answered These are the questions families and adult learners in Osnabrück ask before the first class, with the answers we give them. 1. **Is it a recording?** No. Every class is a live video call with a mentor. Nothing is pre-recorded, and questions are answered while the learner is stuck, not a day later. 2. **Who types the code?** The learner. They share their screen and type every line. The mentor reads along, points to the line with the problem and asks what the learner expected to happen. 3. **What happens in a group of fifteen to twenty?** The mentor explains one idea to everyone, then each learner works on their own code while the mentor goes from screen to screen. Learners at the same level are grouped together. 4. **What if English is not my first language?** Classes are in English only. Mentors speak clearly, adapt to each learner's accent and pace, and write key words in the chat. Python itself uses English keywords, so the two go together. 5. **What do I need?** A laptop or desktop, a browser, earphones and, for older learners, Python itself, which is free and is installed with the mentor in the first class. The mentors are based in India, so an Osnabrück afternoon is their evening. Nobody is passed from mentor to mentor during a course, and after a few weeks the mentor knows which explanations work for them and which mistakes they tend to make. The Python path ## How long does it take to learn Python? Longer than an advert says and shorter than many people fear. The table shows the timings our mentors plan with at two classes a week; every learner is different. | Milestone | Pupils 10 to 12 | Teenagers | Adults | | --- | --- | --- | --- | | Programs with input, loops and conditions | 3 months | 2 months | 1 to 2 months | | Functions, lists and dictionaries | 6 months | 4 months | 3 months | | Reading files and real data | 9 months | 6 months | 4 months | | Classes, testing and web data (APIs) | Second year | 9 to 12 months | 6 months | ### What speeds it up Twenty minutes of practice between classes matters more than anything else. So does a project the learner cares about: a game, a maths question, or data about their own city. Learners who already know Scratch or another language move faster through the first milestone. ### What slows it down Long gaps. Two weeks without any code costs about a week of progress, which is why classes carry on through the school holidays for anyone who wants them. Copying code without understanding it, including code from an AI tool. Our mentors ask learners to explain every line they hand in. Lower Saxony schools ## Where does Python fit into school Informatik in Osnabrück? Informatik is compulsory for every Lower Saxony pupil for two years, late in Sekundarstufe I. These facts were read in the Gesellschaft für Informatik's monitor and the KMK calendar on 2 November 2026. ### The compulsory years The Informatik-Monitor 2026/27 notes that every general school in Niedersachsen has had to teach Informatik in the ninth and tenth school years since 2024/25. Which programming language a school uses is the school's choice. A pupil who has already written Python for a year or two arrives in grade 9 able to concentrate on the ideas, such as algorithms and data, rather than on the syntax. ### After grade 10 Lower Saxony's Gymnasium runs to grade 13: grade 11 is the Einführungsphase, grades 12 and 13 the Qualifikationsphase. Informatik there is a course pupils choose. The monitor lists Niedersachsen among the Länder with the lowest uptake, about one Oberstufe pupil in twelve. Our classes run alongside school and award no marks; the school course is the one that counts. | Break | From and to | | --- | --- | | Herbstferien | 12 to 24 October 2026 | | Weihnachtsferien | 23 December 2026 to 9 January 2027 | | Winterferien | 1 and 2 February 2027 | | Osterferien | 22 March to 3 April 2027 | | Sommerferien | 8 July to 18 August 2027 | Informatik facts: GI Informatik-Monitor 2026/27, Niedersachsen page and the Länder comparison. Holidays: KMK Ferienkalender 2026/27, version of 9 October 2025; Lower Saxony also has free days on 7 and 18 May 2027. Modern Age Coders is independent of the GI, the KMK and the Niedersachsen ministry. The Herbstferien appear again in the project below. A real Osnabrück project ## How many bikes passed Arndtplatz in a week? Reading a city API without losing pages The Datenplattform Osnabrück publishes counts from AI-based traffic sensors through an open API. Our teenagers and adults use one counter to learn the first rule of working with any web API: the answer comes in pages, and a program has to ask for all of them. ### The data GovData lists the dataset Verkehrszählung Osnabrück from SWO Netz GmbH under the Datenlizenz Deutschland Namensnennung 2.0. It describes AI-based sensors that send traffic counts over LoRaWAN and tell apart cars, lorries, motorbikes, bicycles and pedestrians. We use datastream 5521: bicycles counted at Arndtplatz/Martinistraße going into the Arndtstraße, one reading every 15 minutes. A full week would have 672 readings. We fetched the data on 4 November 2026. ### The trap The API never sends everything at once. Our request asks for 200 readings at a time; the reply contains those 200 and a field called @iot.nextLink with the address of the next page. The last page has no next link. A program that reads only the first reply gets a number that looks perfectly reasonable, and is wrong. Nothing warns you. ***Version 1: follow every next link**Python* ``` import json from urllib.parse import quote from urllib.request import urlopen BASE = "https://daten-api.osnabrueck.de/v1.1/Datastreams(5521)/Observations" def fetch_week(start, end): query = (f"$filter=phenomenonTime ge {start} and phenomenonTime lt {end}" "&$select=phenomenonTime,result&$orderby=phenomenonTime asc&$top=200") url = BASE + "?" + quote(query, safe="$=&,") rows, pages = [], 0 while url: with urlopen(url) as reply: page = json.load(reply) rows += page["value"] pages += 1 url = page.get("@iot.nextLink") # missing on the last page return rows, pages school, pages = fetch_week("2026-10-05T00:00:00Z", "2026-10-12T00:00:00Z") print("Pages:", pages, " readings:", len(school), "of", 7 * 96) print("Bikes, 5 to 11 October 2026:", sum(r["result"] for r in school)) ``` It prints `Pages: 4 readings: 636 of 672` and `Bikes, 5 to 11 October 2026: 2063`. The loop keeps going while there is a next link and stops when the API stops sending one. Four pages came back for the week of 5 to 11 October 2026, with 636 of the 672 possible readings: 36 quarter-hours had no reading at all, which is worth reporting next to the total. ***Version 2: what one page hides, and a holiday week**Python* ``` first_page_only = school[:200] print("If we had stopped after page 1:", sum(r["result"] for r in first_page_only), "bikes") holiday, pages = fetch_week("2026-10-12T00:00:00Z", "2026-10-19T00:00:00Z") print("Pages:", pages, " readings:", len(holiday), "of", 7 * 96) print("Bikes, 12 to 18 October 2026 (Herbstferien):", sum(r["result"] for r in holiday)) ``` Run after Version 1. It prints `If we had stopped after page 1: 865 bikes`, then `Pages: 3 readings: 600 of 672` and `Bikes, 12 to 18 October 2026 (Herbstferien): 1559`. With only the first page, the week would have had 865 bikes, fewer than half of the real 2,063. The second week falls in the Lower Saxony Herbstferien and shows 1,559 bikes, but it also has fewer readings, 600 against 636. Dividing by the readings, the school week averaged 3.24 bikes per quarter-hour and the holiday week 2.60, still about a fifth lower. That is our calculation, not a claim about why. | Week | Pages | Readings of 672 | Bikes | | --- | --- | --- | --- | | 5 to 11 October, school week | 4 | 636 | 2,063 | | Same week, first page only | 1 | 200 | 865 | | 12 to 18 October, Herbstferien | 3 | 600 | 1,559 | Data: Datenplattform Osnabrück, SensorThings API, datastream 5521 (Fahrraeder, Arndtplatz/Martinistraße, in die Arndtstraße), listed on GovData as Verkehrszählung Osnabrück under the Datenlizenz Deutschland Namensnennung 2.0, fetched 4 November 2026. Totals, readings and per-reading averages are ours. Because the API is live, a later run can differ if the platform corrects past readings. 1. **Pupils, 10 to 12.** A book has 4 pages of names. You read page 1 and count 20 names. How many names does the book have? What would you need to know first? 2. **Teenagers.** Change `$top=200` to `$top=50`. How many pages now, and does the total change? 3. **Adults.** Group the readings by day using `phenomenonTime` and find the busiest day of each week. 4. **Everyone.** Write a check that stops with an error if the number of readings is below 90 percent of 672. Which of the two weeks passes? Times ## When are online Python classes in Osnabrück time? Pick what suits you. Here is how a few Osnabrück times read on the mentor's clock. | Osnabrück | India this winter | India from 28 March 2027 | | --- | --- | --- | | 15:10 | 19:40 | 18:40 | | 16:40 | 21:10 | 20:10 | | Saturday 14:00 | 18:30 | 17:30 | | Sunday 11:30 | 16:00 | 15:00 | Since 25 October 2026 Germany has been on MEZ, UTC+1; on 28 March 2027 it moves to MESZ, UTC+2, as the Einheitenzeitgesetz sets out. India is fixed at UTC+5:30. That makes the gap 4 h 30 this winter and 3 h 30 from the end of March. The rows are conversions only, never fixed batch times. Learners in Georgsmarienhütte, Bramsche, Wallenhorst, Belm or Melle join the same live classes. The booking page shows each slot on your own clock. Milestones ## What can an Osnabrück Python learner do at each step? Five steps we use in our progress notes. | Step | What the learner can do | | --- | --- | | 1 | Write a program that asks, decides and answers | | 2 | Use loops that stop at the right time | | 3 | Organise data in lists and dictionaries | | 4 | Read a file or a web API completely and summarise it | | 5 | Check their own results and report what is missing | ### For parents The Arndtplatz project covers steps 4 and 5. A learner who has seen 865 turn into 2,063 knows to ask whether a computer has really read everything. Notes to you describe code written and ideas explained. ### For learners If an answer can come in pages, assume it does. Report how many readings you got, not just the total.

Ritu Kedia Parent Questions from Osnabrück ## Online Python classes in Osnabrück: questions and answers ### Are the classes in German? No. Classes are live and taught in English only. The mentors, who work from India, adapt to each learner's pace and accent and put key terms in the chat, so learners who are not fluent in English can follow. ### Is an online Python class live or recorded? Live, always. A mentor is on video for the whole hour, sees the learner's screen and helps in real time. Nothing is pre-recorded. ### How long does it take to learn Python? Our mentors plan with about two months for a teenager to write programs with loops and conditions, and about six to work with real data, at two classes a week. Adults often move faster and children of ten to twelve a little slower; every learner differs. ### When are classes in Osnabrück time? Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays. Mid-afternoon after school and weekend late mornings are common choices in Osnabrück. ### When does Informatik start at Osnabrück schools? For every pupil in the ninth school year: the Gesellschaft für Informatik reports it as compulsory in grades 9 and 10 across Lower Saxony since 2024/25. In the Oberstufe it is a course pupils can choose. ### What is an API, and why does the project use one? An API is a way for programs to ask a website for data. The Osnabrück platform answers in pages of readings, so the project teaches learners to follow every page. Working with APIs is a normal part of real Python work. ### Is the bike data really from Osnabrück? Yes. It comes from the Datenplattform Osnabrück traffic sensors, datastream 5521 at Arndtplatz/Martinistraße, listed on GovData under the Datenlizenz Deutschland Namensnennung 2.0 and fetched on 4 November 2026. The totals are our own. ### Can an adult with no experience start online Python? Yes. The Python Masterclass starts from nothing. Adults who already know some Python often choose Python Web Development, where they build and use APIs themselves. ### How big are the classes? Fifteen to twenty learners at a similar level in a group class. One-to-one classes are private, two a week. ### How do I pay? By the month. The fee is shown in euro at the European Central Bank reference rate and charged in US dollars, which your bank converts, so the statement can differ by a little. The first class is free.
