Prospect in the Census

A compact inner-north council

2021 Census QuickStats for the City of Prospect (ABS code LGA46510), alongside South Australia.

City of Prospect, 2021
Measure	City of Prospect
Residents	22,272
Median age	37
Families	5,884
Private dwellings	9,468
People per household	2.5

Prospect beside South Australia
Indicator	Prospect	South Australia
Adults with a bachelor degree or higher	40.3% (7,428)	22.7%
Employed people in professional jobs	32.6% (4,010)	21.5%
Workers who caught a bus to work	6.2% (759)	3.1%
Flats or apartments	14.5% (1,253)	6.8%

Children

Prospect counted 1,155 children under five, 1,344 aged 5 to 9 and 1,355 aged 10 to 14.

Students

24.8% of residents in education, 1,690 people, were at university, against 16.7% statewide.

Size

At about 7.8 square kilometres, the council area sits just north of the Adelaide park lands.

Because small Census cells are adjusted slightly by the bureau, the numbers are shown unchanged and never combined.

Signature project

The ranking that came back empty

The script counts Wednesday 21 October 2026 visits for each of the 84 stop records inside the City of Prospect, stores them as (stop, visits) pairs, then ranks them.

What our run printed (Python 3.13.6)
Line	Output
ranked = pairs.sort(key=..., reverse=True)	ranked = None
print(ranked[:3])	TypeError: 'NoneType' object is not subscriptable
pairs[:3] after the sort	Already sorted: the list itself changed
sorted(counts.items(), key=..., reverse=True)[:3]	A new, ranked list

The top of the ranking (our count)
Stop record	Wednesday visits
Stop 13 North East Road, north-west side	222
Stop 7A Torrens Road, north-east side	129
Four records, on Main North Road and North East Road	125 each

In place

list.sort() rearranges the list it belongs to and returns None, a signal that nothing new was created.

New list

sorted() leaves the original alone and returns a fresh sorted list, which is what the assignment expected.

The tie

Third place is shared by four records at 125 visits, so "top three" needs a rule for ties as well as a working sort.

A Python convention

Methods that change an object in place, such as sort, append, reverse and extend, return None. Assigning their result is almost always a mistake, and the None usually surfaces a few lines later, far from the real cause.

Stop records and trips come from the Adelaide Metro timetable, version 1708. Membership of the City of Prospect is our point-in-boundary check, and the output lines are copied from our own run.

Python lists

Change in place, or make a new one?

Knowing which operations mutate and which return a copy prevents a whole family of bugs.

Mutating and non-mutating pairs
Changes the list, returns None	Returns something new	Note
lst.sort()	sorted(lst)	sorted works on any iterable
lst.reverse()	reversed(lst) or lst[::-1]	reversed gives an iterator
lst.append(x)	lst + [x]	The + version copies
lst.extend(other)	lst + other	Same idea

Primary learners

Tidy a toy shelf yourself, or ask for a photo of a tidied shelf: one changes the shelf, one gives you something new.

Secondary learners

Reproduce the Prospect None, read the traceback, and fix it with sorted() and with a separate sort() call.

Adults

Watch for assignments from in-place methods in scripts, including pandas calls that take inplace=True.

Linters and type checkers often flag this pattern because the assigned value is always None. Running one is a cheap way to catch it before the TypeError does.

Coding and AI

AI fixes the TypeError. Does it explain the None?

Sometimes. The fix is easy; the understanding is what prevents the next one.

Paste the traceback into an assistant and it will likely suggest sorted(). Good. But the same misunderstanding returns with reverse(), append() and pandas inplace calls, each failing somewhere new.

Learners who know why sort() returns None spot the whole family of mistakes in AI-written code before running it. That is the difference between fixing one bug and preventing a dozen.

In Prospect, the learner who understands in-place methods reads AI code without surprises. The longer argument is in why teenagers should still learn to code in 2026.

FAQ

Prospect Python questions

What Prospect families and adult learners ask most.

What is the population of the City of Prospect?

The 2021 Census QuickStats count 22,272 residents in the City of Prospect, with 9,468 private dwellings and a median age of 37.

Why does list.sort() return None?

Because it sorts the list in place. Python's convention is that methods which change an object return None, so you cannot mistake them for operations that make a copy.

What is the difference between sort() and sorted()?

list.sort() changes the existing list and returns None. sorted() works on any iterable and returns a new sorted list, leaving the original unchanged.

Which Prospect stop had the most Wednesday buses?

Stop 13 on the north-west side of North East Road led with 222 timetabled visits on 21 October 2026, our count from the Adelaide Metro feed.

Is my nine-year-old ready for Python?

Often, yes, if Scratch already feels easy and typing is comfortable. A free first lesson will show us.

Do teenagers learn with Claude?

No. Claude-based courses start at 18; younger learners use other AI tools.

Is there a classroom in Prospect?

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

What do lessons cost for Prospect learners?

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.

Does the Prospect group course include Copilot Studio?

No. Copilot Studio stays in private lessons; in groups, agents are built with Python.
