Different methods produce them, so both appear here unsubtracted. ### Apartments are rare Only 302 dwellings, 0.4%, were flats or apartments, compared with 6.5% across Western Australia. ### Schools Our map test counts 50 government schools inside the council outline, 38 of them primary schools. Because the Census was held during the pandemic, journey-to-work answers describe that week. The ABS also rounds shares and perturbs small counts slightly, so its rows may not sum exactly to its totals; we reproduce its figures as printed. Signature project ## Look before you leap, or ask forgiveness? Each Main Roads count site has an average weekday volume and, usually, an average weekend volume. Learners want the weekend-to-weekday ratio for every Wanneroo site. The first attempt divides one by the other for all 97 rows, and Python stops at the fifth with a TypeError, because that site's weekend value is None. | Approach | Sites kept | Result | | --- | --- | --- | | Divide every row | 0 | Crashes at row 5 with TypeError | | LBYL: check for None first | 74 | Median ratio 0.793 | | EAFP: try, except TypeError | 74 | Median ratio 0.793 | | Replace None with 0 | 97 | Mean drops from 0.793 to 0.605 | ### Two honest styles Checking first and catching the specific error give the same 74 ratios. Python programmers often prefer the try style, but here the choice is about clarity, not correctness. ### The zero trap Filling gaps with zero keeps all 97 rows and looks complete. It invents 23 empty weekends and pulls the average ratio down by almost a quarter. ### The broad except Catch every exception and mistype one field name, and the loop raises KeyError on every row, catches it, and keeps 0 of 97 sites with no message at all. ### What the 74 ratios show Most Wanneroo roads are quieter at weekends: the median site carries about four-fifths of its weekday traffic. Three sites run the other way, led by Indian Ocean Drive north of Breakwater Drive, whose weekend average is 1.178 times its weekday figure. The steepest weekend drop is on Flynn Drive east of Wanneroo Road, at 0.541. Volumes are from the Main Roads Traffic Digest, downloaded on 12 October 2026, for the 97 sites Main Roads assigns to the City of Wanneroo. Of the 23 sites without weekend averages, 21 have a 2024/25 count year. Each ratio compares two numbers from the same site and year; the medians and means are our own calculation. Writing it properly ## Catch the error you expect, and only that one The lesson ends with one rule: name the exception you mean, keep the try block small, and record what was skipped. | Step | Learner task | | --- | --- | | 1 | Load the Wanneroo rows and run the naive loop to see the TypeError. | | 2 | Write the LBYL version with an explicit None check. | | 3 | Write the EAFP version catching only TypeError, and list the skipped sites. | | 4 | Plant a field-name typo, wrap it in except Exception, and watch every row vanish. | Step 3 asks learners to print the skipped list, not just count it. Four of the gaps sit on Wanneroo Road and five on Marmion Avenue, so a road-by-road summary built from the 74 survivors would quietly under-represent those roads. Learners finish by writing one sentence that reports the coverage alongside the answer: 74 of 97 sites had a weekend figure. ### Younger learners Program a robot that checks a door is open before walking through, then one that tries the door and steps back if it is locked. ### Teenagers Write both versions, test them on rows with gaps, and explain why except Exception is dangerous. ### Adults Review error handling in work scripts and replace silent broad excepts with named ones and logs. Around Wanneroo ## Counted roads and the coming school year Facts from Main Roads and the WA Department of Education. ### Busiest counter Joondalup Drive west of Wanneroo Road averages 44,223 vehicles a day across the week, from a 2024/25 count. ### Wanneroo Road With 17 count sites, Wanneroo Road has more counters than any other road in the council. ### 2027 starts WA public school students go back on Monday 1 February 2027, and the first term runs until Friday 9 April. Boundary note Figures use the ABS council boundary of about 683.3 square kilometres. Traffic sites follow the council Main Roads records; school counts use our own point-in-polygon test.

[Python Masterclass](/courses/python-programming-masterclass-zero-to-advanced-college)[Python Automation Course](/courses/python-ai-automation-masterclass-college)Python and AI ## Do AI assistants handle errors well? They often write the broad catch-all, because it makes code run. Ask an assistant to fix the Wanneroo crash and a common suggestion is to wrap the loop in except Exception. The error disappears, and so might every row, the next time a field name changes. A learner who has watched 97 sites become 0 will ask which exception is expected, how many rows were skipped and why. That turns a quick patch into reliable code. In Wanneroo classes, a script that runs is only the start of the review. The longer argument is in [is coding still worth learning in 2026](/blog/is-coding-worth-learning-2026). Delivery ## How lessons reach Wanneroo Classes are taught live over video, which spares families the long drives of the outer north. ### Teacher present Each lesson is live, with code checked while learners type. ### Term-based Lessons line up with WA school terms and stop for holidays. ### Try it first A free trial lesson leads to a written plan. ### Group options Fifteen to twenty learners per level, or private sessions. ### Regular schedule Two sessions every week, around eight a month. ### India hours A 5pm Wanneroo session starts at 2:30pm Indian time. No seasonal shift Daylight saving in Western Australia last ended in March 2009, the IANA time zone database shows, so lesson times keep the same two-and-a-half-hour gap with India. Fees ## Wanneroo class fees All learners pay the same fees. First class**USD 0** No fee for the first lesson, which comes with a plan. Group tuition**USD 100** Groups: roughly eight lessons a month, fifteen to twenty learners. Private tuition**USD 150** Private: roughly eight lessons a month with one teacher. Fees are billed in US dollars and start only when the trial has set the course and a regular weekly time. Holiday and missed-lesson details are on the pricing page.

FAQ ## Wanneroo coding and Python questions Frequent questions from families and adults in Wanneroo. ### What was the City of Wanneroo's population? The 2021 Census counted 209,111 residents with a median age of 35. The ABS estimate for 2025 is 246,147. ### What do EAFP and LBYL mean? EAFP is easier to ask forgiveness than permission: try the operation and catch the error. LBYL is look before you leap: check conditions first. ### Which style should beginners use? Either, as long as the check or the caught exception is specific. The real mistake is catching every exception and hiding problems. ### Why not replace missing values with zero? Because zero is a measurement and missing is not. In Wanneroo it would invent 23 empty weekends. ### When can a child start Python? Often around 9 or 10, after some block coding. The free lesson checks readiness. ### How many traffic counters does Wanneroo have? Main Roads lists 97 count sites on 34 roads in the City of Wanneroo, 74 of them with a weekend average. ### Do you have a centre in Wanneroo? No. Lessons are live online only, we have no Australian office, and our listed phone number is Indian. ### What do Wanneroo 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. ### How are groups arranged? By level and pace, fifteen to twenty learners, not by age or suburb. One-to-one lessons are available when no group time fits. ### Can adults learn Python here? Yes. Adults study in adult groups or privately, often to automate spreadsheets and reports.
