Online coding and Python classes in Moreton Bay

What are the best online coding and Python classes in Moreton Bay?

Live Python lessons in which a Moreton Bay teenager or adult works with data big enough to matter, measures what their code costs, and explains the trade-offs to a teacher. The council area counted 476,340 people at the 2021 Census. Lessons run online, privately or in a small group at the same level, and the first lesson is free.

Translink publishes its whole south east Queensland timetable as open data: every trip, every stop, every scheduled time. Inside the Moreton Bay council boundary that comes to 1,347 stops and 137,865 timetabled stop times in the current feed, from Kippa-Ring and Petrie stations to the buses of Bribie Island. Load them into Python as dictionaries and they take 38.6 megabytes. Load the same values into a class that declares its fields with __slots__ and they take 13.3. Nothing about the timetable changed, only the containers holding it. Our Moreton Bay learners find out where memory goes in a Python program and how to stop wasting it.

Moreton Bay in the Census

A council area of 476,340 north of Brisbane

The 2021 Census for the Moreton Bay council area, placed beside Queensland and Australia.

Moreton Bay was home to 476,340 people with a median age of 39. They made up 132,607 families and lived in 188,200 private dwellings, at 2.6 people per household.

Moreton Bay against Queensland and Australia (2021 Census shares)

Technicians and trades workers (32,335 people)14.7%13.7%12.9%

Units and flats

There were 7,974 flats and apartments, 4.7% of dwellings, against 12.5% for Queensland.

Fifteen to nineteen

Residents aged 15 to 19 numbered 30,026, or 6.3% of the population.

Twenty to twenty-four

Another 27,256 residents were aged 20 to 24, 5.7% of the total.

The ABS estimates 532,445 people in Moreton Bay at 30 June 2025. Because the bureau adds small random changes to Census cells, rows may not sum to totals; all figures are printed as published, and we never total rows ourselves.

Signature project

How much memory does Moreton Bay's timetable take in Python?

The 137,865 stop times at Moreton Bay stops in Translink's open timetable feed, loaded seven different ways and measured with Python's tracemalloc.

Same 137,865 records, seven containers (our measurements, Python 3.13, 10 October 2026)
ContainerMemory for all recordsBytes per record
Dictionary38.6 MB272
Plain class18.8 MB176
Dataclass18.8 MB176
Named tuple15.5 MB96
Tuple14.4 MB96
Class with __slots__13.3 MB88
Dataclass with slots=True13.3 MB88

1. Pick out the stops

The feed lists stops by coordinates. A point-in-polygon test against the ABS council boundary keeps the 1,347 inside Moreton Bay and drops the northern Brisbane suburbs a simple rectangle would catch.

2. Load seven ways

Each stop time has seven fields: trip, arrival, departure, stop, sequence and two pickup flags. The same strings and numbers go into every container, so only the container changes.

3. Measure, do not guess

tracemalloc counts the bytes each version allocates. Dictionaries cost almost three times as much as slotted objects for exactly the same timetable.

Where the bytes go

An ordinary Python object keeps its attributes in a hidden dictionary, built to accept new keys at any time. Declaring __slots__ tells Python the fields in advance, so it stores them in fixed positions with no dictionary at all. Across 137,865 records that saves 25.3 megabytes against plain dictionaries. The whole south east Queensland feed holds 2,879,577 stop times, roughly 21 times as many, which is where these choices stop being academic.

The feed is Translink's, valid from 7 October to 6 December 2026, used under its open licence. Memory figures are our own, measured on Python 3.13.6; other versions and platforms give somewhat different numbers, which is why learners measure on their own machines.

Measuring memory

How to find out what your data really costs

Practised on Moreton Bay's timetable, then applied to logs, sensor readings and any program that holds many small records.

Steps in the Moreton Bay memory study
StepToolWhy
Fix the data firstLoad the strings once and reuse themOnly the container should differ between runs
Measure allocationtracemallocCounts what each version adds, not what the process already held
Inspect one objectsys.getsizeof on the object and its __dict__Shows 272, 176 and 88 bytes directly
Weigh the trade-offTry adding a new attributeSlotted objects refuse, which is the price of the saving

Memory optimisation is not always worth it. For a few thousand records the difference is invisible. The skill is knowing how to measure, so the decision rests on numbers rather than on habit or a rule copied from a forum.

Secondary students

Load the stop times as dictionaries, then as a small class, and compare sys.getsizeof for one record.

University students

Profile all seven containers with tracemalloc, explain each result and test how attribute access speed compares.

Adults at work

Before scaling a script up to millions of rows, measure the container cost on a sample like this one.

Modern Age Coders is not affiliated with Translink, the Queensland Government, the ABS or the City of Moreton Bay. The timetable and statistics belong to them; the measurements are our own.

Coding and AI

Would an AI assistant choose a lean container?

It usually reaches for a dictionary.

Ask a chatbot to load the Moreton Bay timetable and it will most likely produce a list of dictionaries, the most familiar pattern in its training. It works, and it uses almost three times the memory of a slotted class for the same records.

Our Moreton Bay learners let AI write the loader, then measure it with tracemalloc and try the alternatives themselves. They learn to ask the assistant for the trade-offs, not just the code.

A Moreton Bay learner who has measured 38.6 megabytes shrink to 13.3 will check the cost of AI-written code before trusting it at scale, whatever arrives after 2026. The longer argument is in why understanding code still beats copying it.

FAQ

Moreton Bay Python class questions

Questions Moreton Bay families and adult learners ask before they book.

How many people live in Moreton Bay?

The 2021 Census counted 476,340 people in the Moreton Bay council area. The ABS estimate at 30 June 2025 is 532,445.

What does __slots__ do in Python?

__slots__ is a class attribute that lists the only fields an object may have. Python then stores those fields in fixed slots instead of a per-object dictionary, which saves memory and stops new attributes being added by mistake.

What is the Moreton Bay timetable project?

Learners download Translink's open timetable feed, keep the stops inside the Moreton Bay council boundary, load the 137,865 stop times in seven kinds of container, and measure the memory each one uses with tracemalloc.

Is a dataclass more efficient than a dictionary?

In our Moreton Bay measurements a plain dataclass used 18.8 MB against 38.6 MB for dictionaries, and a dataclass with slots=True used 13.3 MB. The exact numbers vary with Python version, so learners measure on their own machine.

Can QCE students join?

Yes. Year 11 and 12 students fit lessons around their QCE subjects, and any assessed work stays entirely their own.

What lesson times suit Moreton Bay?

After school, evenings and weekends, agreed in the trial and written in Queensland time, four and a half hours ahead of India time.

Is there anything for primary school children?

Yes, from age 6 with visual coding tools; the timetable project here is designed for teenagers and adults.

Is there a Modern Age Coders office in Moreton Bay?

No, and we do not claim one. Teaching is live and online only, with no premises anywhere in Australia. A learner needs a laptop or desktop, working sound and a steady connection, and the contact number on this page is an Indian number.

What do online Python classes in Moreton Bay cost?

The first lesson is free. After that a group place costs USD 100 a month for two live lessons a week, about 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 agreed before any payment.

How large are the groups?

Between five and ten learners, matched on level, pace and goals rather than on age or postcode. When no group fits a workable time, one-to-one lessons are offered instead.
