All figures are for the suburb and locality rather than The Hills Shire. Small counts are randomly adjusted by the bureau, so published parts are never added up here to make a new total. Signature project ## A command-line tool with three silent bugs The tool reads the NSW government school locations file and takes three options: --suburb, --secondary and --since. Every run below finishes without an error; only some are right. | Command-line options | First version | Fixed version | Should be | | --- | --- | --- | --- | | --suburb "Baulkham Hills" | 1 school | 7 schools | 7 | | --secondary False | 3 high schools | not accepted; use --no-secondary | 4 primary schools | | --no-secondary | not accepted | 4 primary schools | 4 | | --since 975 (typo for 1975) | 0 schools | 7 schools | 7, since every year is after 975 | | --since 1970 | 5 schools | 5 schools | 5 | ### The hidden space Six of the seven suburb values in the file end with a space, "Baulkham Hills ", so an exact comparison finds only Model Farms High School. Stripping whitespace on both sides brings back all seven. ### type=bool argparse hands the text "False" to bool(), and any non-empty string is True. The tool silently swaps the four primary schools for the three high schools. BooleanOptionalAction adds a proper --no-secondary flag instead. ### Years as text Without type=int, the year arrives as a string and is compared letter by letter: "1967-01-01" is smaller than "975" because 1 comes before 9. Converting both sides to integers fixes it. ### One line that stops the second bug Swap `type=bool` for `action=BooleanOptionalAction`, imported from argparse, in the --secondary line. The tool then understands --secondary and --no-secondary, and "--secondary False" becomes an error the user can see. School names, suburbs and first-teacher dates are from the NSW Department of Education's school locations file; the commands, counts and fixes are our own Python run. Hardening the tool ## Making a tool other people can trust After the three fixes, learners add the habits that real command-line programs share. | Addition | What it does | Baulkham Hills check | | --- | --- | --- | | --help text | Explains every option, written by argparse from the code | A parent can run it without reading Python | | choices= | Rejects levels the file does not contain | "Secondary" accepted, "Senior" refused | | Exit codes | Returns 1 when nothing matches | A typo in the suburb is reported, not hidden | | A test per bug | Runs the tool with each option and checks the count | 7, 4, 3 and 5 schools | ### Children Write a quiz in Python that asks a question and checks the typed answer, spaces and all. ### Teenagers Build the school tool, break it on purpose and write a test for each of the three bugs. ### Adults Turn a weekly spreadsheet job into a script with options, and stop editing code to change one setting. The school locations file is published by the NSW Department of Education, which has no link with Modern Age Coders. Schools and the school year ## The seven schools the tool should find All seven are in The Hills Shire, and their first-teacher dates run from 1967 to 1982. | School | Level | First teacher | | --- | --- | --- | | Baulkham Hills North Public School | Primary | 1967 | | Jasper Road Public School | Primary | 1967 | | Baulkham Hills High School | Secondary | 1971 | | Crestwood Public School | Primary | 1972 | | Model Farms High School | Secondary | 1975 | | Crestwood High School | Secondary | 1981 | | Matthew Pearce Public School | Primary | 1982 | ### Spring break 2027 Eastern division holidays run from Monday 27 September to Friday 8 October 2027. ### Term 4 2027 Pupils go back on Tuesday 12 October, and the year ends on Monday 20 December. ### Classes and holidays Baulkham Hills groups take the same breaks and restart in their regular slot.

[Python Automation Course](/courses/python-ai-automation-masterclass-college)[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)Coding and AI ## An AI assistant wrote type=bool too The mistake is common enough in published code that assistants repeat it. Ask an assistant for a command-line tool with a yes or no option and it may well write type=bool. The tool runs, the help text looks right, and --secondary False quietly means True. Nothing on screen says the Baulkham Hills primary schools have been dropped. A learner who has watched bool("False") return True knows to try the false case before trusting any option, whoever wrote the code. In 2026 code is cheap to generate; Baulkham Hills learners who test each option are the ones whose tools are worth running. The longer argument is in [why teenagers should still learn to code in 2026](/blog/is-coding-worth-learning-2026). Delivery ## Live lessons for Baulkham Hills learners at home Classes happen over live video, which suits busy Baulkham Hills households with no drop-offs. ### Live, not recorded The teacher talks through each line with the learner while it is being written. ### NSW terms Stages, years and the school calendar match what local schools use. ### Trial before paying The first class is free and ends with a clear plan for level and timing. ### Fifteen to twenty per group Classmates are matched by ability; one-to-one is offered too. ### Twice a week A regular pair of weekly slots, roughly eight sessions a month. ### Teachers in India A 6pm Baulkham Hills lesson is 12:30pm India time in Sydney summer time and 1:30pm otherwise. Clock changes Daylight saving in Sydney runs from Sunday 4 October 2026 to Sunday 4 April 2027. India stays on one time, so the gap is 5 hours 30 minutes in summer and 4 hours 30 minutes the rest of the year. Every lesson time we give is Sydney time. Fees ## Baulkham Hills lesson fees Every course costs the same, whatever the subject or age. First class**USD 0** Lesson one is free, and the teacher recommends a course and time at the end of it. Group tuition**USD 100** Two classes each week, about eight a month, with fifteen to twenty classmates at the same level. Private tuition**USD 150** Individual lessons on the same twice-weekly rhythm, about eight a month. Baulkham Hills families pay in US dollars, and only after the trial has settled a course and a time. The pricing page sets out holidays, missed classes and changes of format.

The 2021 Census QuickStats for the Baulkham Hills suburb and locality counted 37,415 residents, median age 39, in 10,574 families and 13,155 private dwellings. ### What is argparse? It is the Python standard-library module for reading command-line options. It turns text typed after a program's name into checked values and writes the --help message automatically. ### Why is type=bool a mistake in argparse? argparse passes the typed text to bool(), and every non-empty string, including "False", is True. Use action=argparse.BooleanOptionalAction or store_true instead. ### What does the Baulkham Hills project build? A Python tool that lists the seven state schools giving Baulkham Hills as their suburb, filtered by level and opening year, with tests for the three bugs it starts with. ### Which state schools list Baulkham Hills as their suburb? Baulkham Hills North, Jasper Road, Crestwood and Matthew Pearce public schools, and Baulkham Hills, Model Farms and Crestwood high schools, all in The Hills Shire. ### What age can my child start? Six is a good age for Scratch. Command-line Python projects like this one usually suit learners from about 13. ### What computer is needed? A Windows, Mac or Linux computer or a Chromebook, a microphone with headphones, and a dependable internet connection. ### Do you run classes in Baulkham Hills itself? No. We teach only online and have no premises anywhere in Australia, including Baulkham Hills. Our contact phone number is an Indian number. ### How much do Baulkham Hills lessons cost? The first lesson is free. A group place is USD 100 a month for two live lessons a week, about eight a month, with fifteen to twenty learners; one-to-one is USD 150 a month on the same plan. Nothing is charged before a course and time are agreed. ### How big are the groups? Fifteen to twenty learners, grouped by level and goals rather than age. If no group fits the learner's schedule, one-to-one lessons are offered instead.
