Signature project

Joining two Seattle parks tables, and finding what falls out

The City of Seattle publishes park addresses and park features as two separate public-domain tables on its open data portal. Both carry a park ID called PMAID. We downloaded both on 18 October 2026 and joined them.

What the join shows (our counts from two Seattle Open Data tables, 18 October 2026)
Measure	Count	What it tells a student
Rows in Park Addresses	412	One row per park, one PMAID each
Rows in Park Features By PMAID	1,044	Many rows per park, one per feature
PMAIDs that appear in the features table	282	Not every park has listed features
PMAIDs found in both tables	266	The size of an inner join, counted in parks
Feature rows with no matching address	33, on 16 PMAIDs	Orphans: a join silently drops them
Parks with no feature rows at all	146	Missing from an inner join, kept by a left join

Inner join

Keep only parks in both tables. It looks clean, but 146 parks vanish without warning, and so do the 33 orphan feature rows.

Left join

Keep every park from the address table and attach features where they exist. Now the 146 parks show up with blanks, which is honest.

Anti-join

Ask the reverse question: which feature rows point at a PMAID with no address? Those 16 IDs are the ones to report or investigate.

In pandas the whole lesson is three lines: pd.merge(addr, feat, on="pmaid", how="inner"), the same with how="left", and an indicator=True merge to label which side each row came from. Comparing the row counts after each one teaches more about data than any single chart.

The most common park features (our count from Park Features By PMAID)
Feature	Rows
Play Area	142
Drinking fountains	132
Views	98
Restrooms	89

Ours, not the city’s

Every count here is our own, from downloads on 18 October 2026. The two tables were last updated at different times (the address table in May 2024, the features table in July 2026), which may explain some orphans. We say “may” because the city has not told us; guessing a cause and calling it a fact is the mistake this project is designed to prevent.

Seattle facts we used

Seattle’s parks and council, as the city describes them

Official City of Seattle figures, read on 18 October 2026, set beside the open data.

What the City of Seattle publishes
Topic	Official figure	Source
Park system	a 6,441-acre park system of over 489 parks	Seattle Parks and Recreation, About Us
Share of the city	about 12% of the city’s land area	Seattle Parks and Recreation, About Us
Community centers	25 community centers	Seattle Parks and Recreation, About Us
Swimming	eight indoor swimming pools	Seattle Parks and Recreation, About Us
Picnic shelters	38 parks with reservable picnic shelters	Seattle Parks and Recreation
Sports fields	200+ sport fields, 59 lighted fields	Seattle Parks and Recreation
City Council	Nine members: seven districts and two citywide positions	Seattle City Council

Put the official “over 489 parks” next to the 412 rows in the address table and a student has a real research question: which parks are not in the file, and why? It is a good example of why a dataset is a view of reality, not reality itself. The park with the most listed features in our join is Warren G. Magnuson Park, with 16.

Washington state

Computer science at school in Washington, briefly

The state rule in a sentence, then what it means for a Seattle family choosing classes.

In short: Washington’s school code asks every district that runs a high school to give its students the chance to take a computer science elective, which is an access rule rather than a course every student must pass. We read it in the Revised Code of Washington on 18 October 2026, because the state education agency’s page refused our request that day. By Code.org’s count, 51.2% of Washington high schools listed computer science in 2024 to 2025 (Code.org (2025). 2025 State of AI + CS Education).

If your school offers it

A Seattle student can take the school elective and use our classes for depth: bigger projects, data work like the parks join, or AP preparation.

If the timetable is full

Many students cannot fit an elective around languages, music and sport. A weekly online class keeps coding going without a timetable clash.

Credit questions

Any question about school credit belongs with the school counselor. Our classes do not award Washington credit, and school assignments stay the student’s own.

Class times

Pacific Time, and the widest gap to India in the lower 48

Seattle runs on America/Los_Angeles in the IANA time zone database, the furthest US mainland zone from India.

Choose your times

Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays.

The arithmetic

The gap to India is twelve and a half hours while Seattle is on daylight time and thirteen and a half in winter, so a Seattle afternoon is the next India morning.

Changeover days

Seattle changes clocks on November 1, 2026 (back) and March 14, 2027 (forward); every class is confirmed in Pacific Time.

A date-line puzzle

Because the gap passes twelve hours, a Monday 5 p.m. class in Seattle starts on Tuesday in India. Teen students write a Python check with zoneinfo that prints both dates, a neat test of whether they understand time zones as data.

Coding and AI

Will AI make joining data and writing code unnecessary?

AI can write the merge line. Deciding which join is right is still a human call.

Ask an AI assistant to combine the two Seattle tables and it will most likely produce an inner join, report a tidy result and say nothing about the 146 parks that disappeared. Nothing in the output warns you; you have to know to ask.

That is why our students write joins by hand before they rely on tools. Once they know what each join keeps and drops, an assistant becomes a fast typist rather than an authority. The same habit carries into machine learning, where the training data decides what a model can ever know.

Our AI courses for teens begin with exactly this: the data, the join and the gaps, and only then the model. The longer argument is in is coding still worth learning in 2026.

Delivery

Ballard to Beacon Hill, the same live class

Hills, bridges and traffic make cross-city classes slow. Online, every neighborhood is the same distance away.

Learn from home

Students join from their own room anywhere in Seattle, with no bus or bridge to cross after school.

Washington school year

Lessons follow US grades and Seattle’s school terms, and a teacher never completes assessed work for a student.

Begin with a free class

A genuine coding task with a teacher; at the end, a suggested course, level and slot, and no request for payment details.

Grouped by stage

Batches of fifteen to twenty students at the same point, from Seattle and across the country.

Private option

A teacher for one student, for those who want speed, AP preparation or a quieter setting.

Slots in Pacific Time

Weekdays or weekends, decided by you, confirmed in Pacific Time.

No local office

We have no Seattle center and claim none. Classes are live online, taught from India, and need a laptop or desktop with sound and a reliable connection.

Fees

Class fees for Seattle families

Three items cover it.

First classUSD 0

A free first class with a teacher, ending in a suggested course and level.

Group tuitionUSD 100

A monthly fee for a level-matched batch of fifteen to twenty students.

Private tuitionUSD 150

A monthly fee for one-to-one teaching.

Seattle families pay in US dollars, the same single rate used nationwide. Charges begin only after the free class and once you accept the course and time; holidays and missed lessons are explained on the pricing page.

FAQ

Seattle coding and AI questions

What Seattle families ask before starting.

What ages do you teach in Seattle?

From age 6 with visual blocks, through Python and web development in middle school, to data science, AP Computer Science and machine learning in high school.

What is the Seattle parks join project?

Students download the City of Seattle Park Addresses and Park Features tables, join them on the PMAID key, and compare inner, left and anti-joins to see which parks and rows drop out.

Are the parks counts official?

No. They are our own counts from downloads on 18 October 2026. Official figures, such as over 489 parks, come from Seattle Parks and Recreation.

Must every Washington student take computer science?

No. The state code asks districts that run a high school to offer access to a computer science elective; taking it is the student's choice.

Do your classes count for school credit?

No. We do not grant Washington credit. Our classes add skills and projects alongside school.

When are classes for Seattle students?

Weekdays or weekends, flexible: choose your batch, or for a very personalised plan choose 1-on-1 at your convenience, weekend mornings or weekdays. Every slot is given in Pacific Time.

Why does the class date look different in India?

India is 12 hours 30 minutes or more ahead of Seattle, so an afternoon class in Seattle starts the next morning in India. We handle that and confirm the Seattle time.

Do you have a Seattle location?

No. We teach live online from India only.

What do classes cost?

The fees block lists a free first class and two monthly plans, group or one to one. Nothing is charged until after the free class.
