Vibe Coding and AI Agents Classes in Knox, Melbourne

Knox shares, with Victoria for scale
Proportion	Knox	Victoria

Five to nine

Knox had 9,408 residents aged 5 to 9, which is 5.9% of the council.

Under five

8,428 children, 5.3% of residents, were aged 0 to 4.

Working from home

25.2% of Knox workers (20,582) worked at home on Census day, which fell during a Melbourne lockdown and is not a normal week.

The bureau rounds its published percentages and makes small random changes to protect privacy. We print values exactly as shown and never create totals by adding rows.

Signature project

One missing field, three behaviours

Each sentence comes from one template: "$name is $kind school in $town. In a straight line, the closest metropolitan station is $station, $dist km away." Our lookup gives $kind for primary, secondary and combined schools. The council's one specific-purpose school has no entry, on purpose, so one row is missing a slot.

What each method did with 33 rows (our test)
Method	Rows with a gap	What came out
Template.substitute	1	A KeyError; the run stops and names the missing slot.
Template.safe_substitute	1	A sentence still containing the literal text $kind.
str.format_map with a defaultdict	1	A sentence with the word None where the type should be.

Closest station to each of the 33 schools, straight-line (our calculation)
Station	Schools	Inside Knox?
Ferntree Gully	11	yes
Boronia	8	yes
Bayswater	5	yes
Heathmont	4	no
Upper Ferntree Gully	3	yes
Glen Waverley	1	no
Yarraman	1	no

Loud is good

substitute refuses to build a prompt with a hole in it. The run stops on the one bad row, so a person fixes the lookup before any model sees the text.

Quiet is risky

safe_substitute is meant for partial templates and leaves the placeholder in place. In an agent, that raw $kind goes to the model, which may guess a type and write it confidently.

Wrong is worse

The defaultdict route fills the gap with None. The sentence reads normally, so nothing flags it, and the error flows into every later step.

The rule we teach

Required fields fail loudly; optional fields get a deliberate default. Deciding which is which is the design work, and it happens before any prompt is sent.

Distances are straight-line from each school's listed coordinates to the nearest of the 222 metropolitan stations, ranging from 0.6 km to 6.9 km. They are not travel distances. Six schools are closest to a station outside the council, which is why that column matters. The specific-purpose school is counted but not named.

Templates in Python

Writing a template that fails safely

string.Template is part of the standard library and uses $name placeholders, which keeps prompt text easy to read.

Steps in the Knox exercise
Step	Learner task
1	Build one dictionary of values per school from the state file.
2	Fill the template with substitute and catch KeyError.
3	Print the school row that failed and the missing slot.
4	Decide: fix the lookup, or make that slot optional on purpose.

One Knox example of a finished sentence: "Scoresby Primary School is a primary school in Scoresby. In a straight line, the closest metropolitan station is Glen Waverley, 6.0 km away." Every value in it comes from a file, not from a model.

Children

Fill-the-gap stories in Scratch, where a missing word makes the sprite stop and ask.

Teenagers

Write the template, find the gap, and compare the three behaviours on screen.

Adults

Add required-field checks to the prompts in a work automation before it runs unattended.

Knox schools and stations

From the 2025 Victorian school locations list and the department's station entries for FY24-25.

33 government schools

Knox has 26 primary, 5 secondary, 1 combined primary and secondary, and 1 specific-purpose government school in the 2025 file.

Four stations

Boronia (462,850 entries in FY24-25), Bayswater, Ferntree Gully and Upper Ferntree Gully are inside the council boundary.

Term 1 of 2027

Victorian government school students go back on Thursday 28 January 2027, and Term 1 ends on Thursday 25 March.

Boundary used

Counts use the ABS outline of Knox City Council, about 113.9 square kilometres. School addresses inside it include Ferntree Gully, Rowville, Bayswater, Wantirna, Boronia and Knoxfield.

Coding and AI

Why do Knox learners need code if agents can write it?

Because an agent is only as reliable as the instructions and data it is given.

Vibe coding means describing what you want and letting an AI tool draft the code. It is fast, and it works well when the person describing the job can read the result and spot a placeholder that never got filled.

The Knox exercise is small on purpose. One empty field among 33 rows is easy to miss, and an agent repeating that mistake across thousands of rows is how real systems publish nonsense. Learners who have seen it once write the check without being asked.

In our Knox classes, learners direct the AI and verify its work. The longer argument is in why teenagers should still learn to code in 2026.

FAQ

Knox vibe coding and AI agents questions

Asked by Knox parents and adult learners before booking.

How many people live in Knox?

Knox City Council counted 159,103 residents in the 2021 Census, with a median age of 40.

What is vibe coding?

Vibe coding is building software by describing what you want to an AI tool, which drafts the code. The learner still reads, tests and fixes that code.

What is an AI agent?

An AI agent is a program that uses a language model to take steps towards a goal, such as filling templates, calling tools and checking results.

What is the difference between substitute and safe_substitute?

In Python's string.Template, substitute raises a KeyError when a placeholder has no value. safe_substitute leaves the placeholder text in place instead.

Are AI agents classes suitable for children?

Younger children learn the ideas through Scratch and kid-safe tools. Building agents with real AI services suits teenagers and adults.

Can adults learn to use AI coding agents?

Yes. Our coding agents course is for adults aged 18 and over, in groups or one to one.

Do you have a centre in Knox?

No. Lessons are live online only, we have no Australian office, and our listed phone number is Indian.

What do Knox classes cost?

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.

Who is in each group?

Fifteen to twenty learners at a similar level and pace, not sorted by age or suburb. One-to-one lessons suit anyone no group time fits.

How many government schools does Knox have?

The 2025 Victorian school locations file lists 33 government schools in Knox City Council.
