Reading these numbers: census cells are adjusted by small random amounts so that no person can be identified, which means a table's rows may not total exactly. We print the bureau's own totals and percentages and do not add up rows to make new ones. Signature project ## Three silent bugs in one school file, and the dataclass that catches them The NSW Department of Education publishes a spreadsheet of every government school. We loaded the 21 rows for the Port Stephens council area the quick way, as text in dictionaries, and recorded what went wrong before rewriting the loader properly. | Question | Quick answer | Correct answer | Cause | | --- | --- | --- | --- | | Which school is furthest south? | Karuah Public School | Fern Bay Public School | Negative latitudes compared as text | | Pairs of schools in the right north-south order | 0 of 210 | 210 of 210 | Every comparison is reversed | | Schools with a first teacher before 1900 | 0 | 9 | A misspelt key read with .get() | | Schools in Raymond Terrace | 3 | 4 | One row written in capitals | | Check | Result | | --- | --- | | Oldest first-teacher date | Hinton Public School, 1 April 1849 | | Newest first-teacher date | Grahamstown Public School, 31 January 1994 | | First-teacher dates in the 1800s | 9 | | First-teacher dates in the 1900s | 12 | | Changing a field after loading | Refused with FrozenInstanceError | ### 1. Load it quickly csv.DictReader gives every value as a string. Sorting, comparing and counting all appear to work, which is exactly why the mistakes are dangerous. ### 2. Spot the symptoms Check a few answers against a map and the calendar: the southernmost school is the wrong one, the 1800s look empty, and one town has fewer schools than it should. ### 3. Load it properly Define a School dataclass with a date, two floats and a cleaned town name. Conversion happens once, at the door, and every later step is safe. ### Why text and numbers sort differently As text, "-32.65" and "-32.87" are compared character by character, and at the first difference "6" comes before "8". So "-32.65" sorts first, as though it were the smaller value. As numbers, -32.87 is smaller, because it is further below zero. Positive numbers often hide this problem; negative latitudes, which every Australian location has, expose it immediately. All counts on this page come from our own code running on the department's open file. The project is about loading data correctly; it says nothing about any school's size, results or quality, and coordinates are used only to compare north and south. Habits that prevent bad data ## Questions to ask of every file you load The Port Stephens file is small, but the same four checks protect programs that read millions of rows. | Check | What went wrong here | The habit | | --- | --- | --- | | Is every column the right type? | Latitudes stayed as text | Convert at load time, in one place | | Does a missing key fail loudly? | .get() returned None and counted nothing | Use attribute access or a strict lookup | | Are labels written consistently? | Raymond Terrace in two spellings | Normalise case and spaces before grouping | | Can the data be changed by accident? | Plain dictionaries accept any edit | Freeze records that should not change | Asking an AI assistant to load a CSV usually produces the quick version, because it is short and it runs. Learners who have watched it put Karuah at the bottom of the map learn to read generated code with one question in mind: what type is this value, really? That single habit catches a surprising share of real bugs. ### Teenagers Write the quick loader, find each bug by checking answers against reality, then rebuild it with a dataclass. ### University students Type hints, validation libraries and how schema checks fit into a data pipeline. ### Adults Reading work spreadsheets with Python and getting answers that survive a second look. We are independent of the NSW Department of Education, Port Stephens Council and the Australian Bureau of Statistics. The department provides the school list and the bureau the population figures; every bug, count and fix shown here was produced by our own code. Around Port Stephens ## Schools from Hinton to Shoal Bay, 1849 to 1994 A few more things the school list and the NSW calendar reveal. ### A school from 1849 Hinton Public School records its first teacher on 1 April 1849, the earliest date among the 21 Port Stephens schools. ### The peninsula schools Shoal Bay, Salamander Bay, Soldiers Point and Anna Bay all appear in the file's town column, alongside inland places such as Seaham and Karuah. ### The 2027 year Term 1 for NSW Eastern division students runs from Wednesday 3 February to Friday 9 April 2027. A good follow-up exercise Once the dataclass is in place, sorting schools by first-teacher date takes one line, because the class compares records by date. Grouping by cleaned town name is the next step, and it is a natural way to practise dictionaries of lists.

[Python Automation Course](/courses/python-ai-automation-masterclass-college)[Data Analysis Course](/courses/data-analysis-mastery-course-college)Coding and AI ## If an AI writes the loader, why should a Nelson Bay learner understand types? Because the generated code runs perfectly and still gives the wrong school. An assistant asked to read the school file will normally use csv.DictReader and sort by the latitude column. The code is clean, it runs first time, and it names Karuah as the furthest south. Nothing in the output signals a problem, because comparing strings is a perfectly valid thing for Python to do. A learner who has built the dataclass version reads the same generated code differently. They see a string where a float should be, a .get() that could quietly return None, and a town name that has not been cleaned. Finding those three things takes a minute, if you know to look. In 2026 anyone can generate a loader; a Nelson Bay learner who can see the type hiding inside it is the one whose answers hold up. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Delivery ## Shoal Bay to Raymond Terrace, the same online class The 21 schools in our project range from the peninsula towns to inland places such as Hinton and Seaham, and a lesson on video reaches every one of those communities in the same way. ### Peninsula and inland A teenager in Salamander Bay and an adult near Seaham can join one class without anyone crossing the council area. ### Fits the NSW year Plans follow the NSW stages and pause for the four school terms. Older students can connect Python projects to the computing subjects they study. ### The first lesson The trial is a full Python lesson with real code. At the end you get a suggested level, course and lesson time, and no card details are asked for. ### One level per group Each group has fifteen to twenty learners at the same stage, drawn from Port Stephens and other places, so nobody waits for a class to fill. ### A steady rhythm Two lessons a week at the same time, close to eight a month, with holiday and exam breaks agreed ahead. ### Taught from India A 5pm Nelson Bay lesson in August starts at 12:30pm in India; when NSW moves to daylight saving, it starts at 11:30am there. Lesson times stay in local time Daylight saving in New South Wales begins on Sunday 4 October 2026 and ends on Sunday 4 April 2027. India has no daylight saving, so only the India-side time shifts, and every booking is written in Nelson Bay time. Fees ## Fees for Nelson Bay learners The whole price, in three lines. First class**USD 0** One complete Python lesson at no cost, with a recommended level, course and time afterwards. Group tuition**USD 100** About eight lessons a month with fifteen to twenty learners at the same level. Private tuition**USD 150** About eight lessons a month, one learner with one teacher. Invoices outside India are issued in US dollars, so a household in Shoal Bay pays exactly what one in Medowie pays and no Port Stephens price list exists. Billing starts only after the trial has fixed a course and a time; holidays, missed lessons and changing format are covered on the pricing page.

FAQ ## Nelson Bay Python class questions Questions we hear most from Nelson Bay and Port Stephens learners and parents. ### How many people live in the Nelson Bay urban area? The 2021 Census QuickStats count 28,418 residents in the Nelson Bay Significant Urban Area. The median age there was 54, compared with 39 across New South Wales. ### What is a Python dataclass? A dataclass is a short way to define a class that mainly holds data, such as a school with a name, a date and a location. Python writes the setup code for you, and options such as frozen and order make records unchangeable and sortable. ### What is the Nelson Bay schools project? Learners load the NSW Department of Education's file for the 21 public schools in the Port Stephens council area, find three silent bugs that plain text causes, and rewrite the loader with a dataclass. The quick version names the wrong school as furthest south and finds no schools before 1900 instead of 9. ### Does the project rank the schools? No. It uses names, dates, towns and coordinates only to practise loading data correctly. Nothing on this page comments on any school's results, size or quality. ### Can Year 11 and 12 students get help with computing? Yes. Senior students taking NSW computing or maths courses get lessons that fit their stage and term calendar. Assessed school work has to be the student's own; we teach the methods and never write marked work. ### When do lessons take place? Times are chosen at the trial and written in Nelson Bay time, often after school or on Saturday mornings. Our teachers in India are 4.5 hours behind Nelson Bay in winter and 5.5 hours behind during NSW daylight saving. ### Do you teach younger children? Yes, from age six, starting with Scratch and visual programs before moving to typed Python. The loader project on this page suits teenagers and adults. ### Is there a Modern Age Coders centre in Nelson Bay? No, and none is claimed. All lessons are live and online and we have no premises anywhere in Australia. A learner needs a laptop or desktop, working sound and a steady connection; the contact number shown is Indian. ### What do Nelson Bay Python classes cost? The first lesson is free. After that a group place is USD 100 a month for two live lessons a week, around eight a month, with fifteen to twenty learners, or USD 150 a month for the same pattern one to one. Course, format and time are settled before any payment. ### How big are the groups? Fifteen to twenty learners, grouped by level, pace and goals rather than by age or postcode. When no group suits the time a learner needs, one-to-one lessons are offered instead.
