Published percentages are rounded and small cells are randomly adjusted by the ABS for privacy. We reproduce the numbers exactly and do not combine categories into new totals. Signature project ## Reading 688,380 rows without holding them First we found the 82 stop points (platforms, entrances and other station nodes) that fall inside the ABS outline of Maroondah. Then we scanned stop_times for rows at those points in two ways: readlines() into a list, and a plain for loop over the open file, which yields one line at a time. tracemalloc recorded the peak memory of each. | Approach | Rows found | Peak memory | Median time, 3 runs | | --- | --- | --- | --- | | Read the whole file into a list | 12,164 | 90.1 MB | 1.1 s | | Stream line by line | 12,164 | 0.035 MB | 0.92 s | | First 200,000 lines into a list (islice) | 4,971 | 25.67 MB | not timed | | First 200,000 lines streamed (islice) | 4,971 | 0.035 MB | not timed | | Station | Rows in stop_times | | --- | --- | | Ringwood | 3,787 | | Heatherdale | 2,995 | | Heathmont | 1,802 | | Croydon | 1,790 | | Ringwood East | 1,790 | ### Memory, not speed Streaming was only a little quicker here, 0.92 s against 1.1 s. The real gain is memory: the list version holds every line at once, while the stream holds one. ### When a list is fine A 56.6 MB file fits easily on a laptop, and a list lets you loop twice or jump to row 500. For a file this size, the simple version is a reasonable choice. ### When streaming wins Feeds grow, and servers have less memory than laptops. Code written as a stream keeps working when the file is ten times bigger, without a single change. ### Two data sets, one station, two answers Heatherdale's two platform points in the timetable feed fall 62 m and 86 m inside the ABS outline of Maroondah by our calculation. The same station's point in the patronage file sits about 50 m outside it. Which council a boundary station "belongs" to depends on whose coordinates you use. Rows count every scheduled stop in the feed downloaded on 10 October 2026, across all its service days, so they are not trains per day. Taking just the first 200,000 lines with islice found 4,971 of the 12,164 rows, a quick way to test code before the full run. Generators in plain words ## Lazy by design A Python file object is already an iterator. Looping over it reads one line, hands it over, and forgets it. | Tool | What it does here | | --- | --- | | for line in f | Reads the file one line at a time. | | A generator expression | Filters lines without building a list. | | itertools.islice | Takes only the first N lines, for quick tests. | | tracemalloc | Reports the peak memory a block of code used. | The pattern is short enough to remember: open the file, loop, keep only the count. Learners then wrap it in a function that yields matching rows, so the next step of a pipeline can consume them one by one. ### Younger coders Read a story one page at a time instead of photocopying the whole book first, then do it in Scratch with a list. ### Secondary students Measure both versions with tracemalloc and explain the difference in a sentence. ### Adult learners Convert a script that loads a big export into one that streams it. Maroondah facts ## Schools and trains in Maroondah Taken from the 2025 school locations file and the station entries file for FY24-25. ### 23 government schools The 2025 file shows 17 primary, 5 secondary and 1 specific-purpose government school in Maroondah. ### Ringwood leads Ringwood recorded 1,514,250 entries in FY24-25, ahead of Croydon, Ringwood East and Heathmont among stations inside the outline. ### 2027 Term 1 Students at Victorian government schools return on Thursday 28 January 2027, and the term ends on Thursday 25 March. Area covered This page uses the ABS boundary of Maroondah City Council, about 61.4 square kilometres. School addresses inside it include Ringwood, Croydon, Heathmont, Warranwood and Bayswater North.

[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Data Analysis Course](/courses/data-analysis-mastery-course-college)Coding and AI ## Will AI tools make Python skills less useful for Maroondah students? Not for anyone who wants to know whether the code will survive real data. An AI assistant asked to "count the Ringwood rows" will often write the readlines() version, because it is the most common pattern online. On this file it works. On a file ten times larger, on a small server, it may not. A learner who has measured 90.1 MB against 0.035 MB recognises the pattern in generated code and asks for the streaming version. Knowing what to ask for is the skill AI cannot supply on its own. Maroondah learners who understand memory get far more out of AI tools. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Delivery ## Maroondah classes, live online Lessons run on a video call for learners in Ringwood, Croydon or anywhere in Maroondah. ### Working together The learner shares their screen and the teacher guides changes in their own code. ### Victorian terms The class calendar follows state school terms, with holiday breaks. ### Free first session One whole lesson with no charge, ending with our course advice. ### Groups Fifteen to twenty learners per group, matched on level rather than location. ### Twice weekly Two regular lessons each week, near eight per month. ### Across time zones A 3:30pm Maroondah lesson is 10am India time while Melbourne is on daylight saving, and 11am after it ends. Time zones Melbourne daylight saving is in effect from Sunday 4 October 2026 to Sunday 4 April 2027. India has no daylight saving, so we always write lesson times in Melbourne time. Fees ## Maroondah class fees Straightforward fees, the same for everyone. First class**USD 0** Your first lesson is free and comes with honest advice. Group tuition**USD 100** In a group: a month of lessons, normally eight, with fifteen to twenty learners. Private tuition**USD 150** On their own: a month of lessons, normally eight, with a dedicated teacher. Maroondah families pay in US dollars. Nothing is charged until the trial confirms a course and weekly time; the pricing page explains holidays and missed lessons.

Maroondah City Council had 115,043 residents at the 2021 Census, and the median age was 39. ### What is a generator in Python? A generator produces values one at a time, only when asked, instead of building a whole list in memory. Generator functions use the yield keyword. ### What does itertools.islice do? itertools.islice takes a slice of any iterator, such as the first 200,000 lines of a file, without reading the rest. ### How do you measure memory use in Python? The standard tracemalloc module traces memory allocations; get_traced_memory() returns the current and peak sizes for the code you run. ### What age is right for Python? Most children are ready for typed Python between nine and twelve. Scratch suits younger learners. ### Do you teach data analysis to adults? Yes. Adults can study Python and data analysis in groups or one to one. ### Is there a Maroondah office? No. Teaching is live online only; we have no office in Australia, and our listed phone number is Indian. ### What are the fees for Maroondah classes? The first lesson is free. Group classes cost USD 100 a month for two live lessons a week, about eight a month, in groups of fifteen to twenty, and one-to-one classes cost USD 150 a month. You agree the course and time before paying. ### How do you choose a group? We match fifteen to twenty learners on level and pace, not age or suburb, and offer one-to-one lessons if no group time suits. ### Which council is Heatherdale station in? It depends on the data. Timetable platform points fall just inside Maroondah's ABS outline and the patronage file point just outside, by our calculation.
