And before that, the next Helsinki Python is on Monday 18th August at Witted AIcorp:
August Helsinki Python meetup, with Witted AIcorp, Mon, Aug 18, 2025, 4:30 PM | Meetup
It’s currently full, but do join the waitlist, and our Discord to be the first to hear about the next one!
And another PyData Helsinki meetup, this time at Supercell on 22 September, 2025:
Welcome to our next meetup on Wednesday 22nd October, at Zalando.
We’ll have three talks this month:
Naa Ashiorkor Nortey: Python Meets the Senses: Making Sense of Complex Sensor Data
Ever wondered how machines can “smell”? In this talk, I will present how Python can help us explore patterns in data from electronic noses, sensors that detect chemicals around us. You will see how we can uncover insights, understand the effect of environmental factors, and make complex sensor readings easier to understand.
@jpakkane: Typed Python the hardest way
While Python’s dynamic typing is great, it becomes an obstacle as projects get bigger. A common solution for this is to add typing information and enforce it in CI. But what happens if you take this approach and run with it further than anyone probably should? Let’s find out!
Luca Scotton: TBA
And of course the famous HelPy quiz!
See you there!
PS Don’t forget about PyCon Finland next week!
PyData Helsinki is meeting on 11 Nov at Sofia Helsinki, for an evening sponsored by Cactos, a Finnish smart-energy company. Talks:
Olli Ruokojoki: Data-Driven Batteries: Modeling State of Charge and Health from Operational Data
Tuomas Sivula: Stochastic Models in Energy Storage Operating Environments
Quentin Salomé: 
lightning talk (title TBA)
Osvaldo Martin: ArviZ 1.0: Refactoring for flexibility, extensibility, and power
Jouni Seppänen: Python Visualisation Tools
The next PyData Helsinki meetup is on 2 Dec at Reaktor, Yliopistonkatu 4. We have one confirmed talk:
Ville Rantanen: Bottling AI
We’ll be trying something new: a panel discussion on How to Land a (Data) Job in Today’s Market. Our three panelists have interviewed hundreds of candidates for their respective companies, some specifically in data and some in software engineering.
Last time, we introduced the PyData Helsinki quiz with our own spin on the format used by our friends at Helsinki Python. The quiz will make a comeback!
Welcome to our final meetup of the year!
This time we’re wrapping things up in a relaxed pikkujoulut spirit at Beerhouse Kaisla. We’ve reserved a spacious private cabinet for our group starting at 6 PM, so feel free to drop in, grab a drink, and connect with fellow Python enthusiasts.
There are no presentations this time, just good company and end-of-year vibes. But don’t worry, we still have something fun planned: a Christmas-themed HelPy quiz kicking off at 7 PM.
