Join Fay Shaw for a practical, hands-on session focused on data preprocessing — an essential step in any data science or machine learning workflow. Whether you’re new to data science or looking to streamline your current process, this session will introduce actionable tools, techniques, and tips to help you clean, transform, and prepare your data effectively.

Fay will walk through a real-world example using data from *Belmin et al.’s* 2022 Nature paper, **[LivWell: a sub-national dataset on the living conditions of women and their well-being for 52 countries](https://url.us.m.mimecastprotect.com/s/Ux7QC31JO8I7QzDofgfwsQFMfr?domain=nature.com)**. This dataset includes 265 indicators across 447 regions in 52 countries, offering a rich foundation for practical demonstration.

Participants will learn how to:

* Explore and filter data using DataFrame functions
* Clean and manipulate strings
* Apply common transformation techniques
* Structure data for downstream analysis or machine learning

**Prerequisites:** Basic familiarity with Python and working in Colab or Jupyter notebooks.

Data Pre-Processing Best Practices with Pyladies Boston & Women in Data

Online event

Hi all!

You are reading this correctly, in August, we will be having **two** drinkups!

On Wednesday Aug 13th we are having our [monthly Python drinkup](https://www.meetup.com/python-hrvatska/events/310376418/) with a smaller crowd and all the familiar faces you know and love.

But on Aug 21st we will partake in a cross-tech developer meetup!

**7 local developer meetup groups** (us included) are doing a drinkup at the same time, at the same place. It's *Zagreb Developers Drinkup*, and Python Hrvatska will be there!
So, pretty much it's going to be the same format as we do our Python drinkups: no prepared talks or presentations, just a casual chat with your fellow developers, only twist is that they might not speak your language. Mingle around and see what other developers and meetup groups are up to.

We expect a lot of people to attend, so it's going to be a lively event for sure. Also, feel free to invite other developers, colleagues from your company, even if they're not an active members of Python Hrvatska. All developers are invited!

Here's the list of other developers you can expect at the event:

* Elixir Zagreb - https://lu.ma/elixirzg
* Golang ZG - https://www.meetup.com/golang-zg/
* Google Developer Group Zagreb - https://gdg.community.dev/gdg-zagreb/
* JavaScript Zagreb - https://www.meetup.com/javascript-zagreb/
* Ruby Zagreb - https://www.meetup.com/rubyzg/
* ZgPHP - https://www.meetup.com/ZgPHP-meetup/

See you there!

We are continuing our Study group online for the time being.
We are now meeting online in the San Diego Python Discord server! Here is the link to join: [https://discord.gg/8GpWuVvdbQ](https://discord.gg/8GpWuVvdbQ)
There is a "meetup" voice/video channel that we will be using!

We may start meeting in person soon! This will be discussed at the meetup. We are considering having some online, some in-person. Decisions, decisions!

Every Saturday we meet up with the larger Python community (including San Diego PyLadies (http://www.meetup.com/sd-pyladies), Open BioInformatics San Diego (https://www.meetup.com/Open-Bioinformatics-SanDiego/) and San Diego Artificial Intelligence (https://www.meetup.com/SanDiegoAI/)) to chat, learn, and hang out.

Our study group is for everyone on their Python journey, whether you're just starting out, an experienced pro, or anywhere in between. There's no formal instruction, just a bunch of folks who like to code. Sometimes we talk about a specific subject, sometimes answer questions, whatever!

Python Community Code of Conduct (http://www.pythonsd.org/coc): Python is much more than a software language. Python is a vibrant community made up of members from around the globe with a diverse set of skills, personalities, and experiences. It is through these differences that our community experiences great successes and continued growth. Overall, we're good to each other. We contribute to this community not because we have to, but because we want to.

**Cameron McEwing: Building Interactive Agentic Systems**

Join the Christchurch Python meetup virtually. Point your web browser at [https://bbb2.nzoss.nz/b/men-pg1-cot-ai2](https://bbb2.nzoss.nz/b/men-pg1-cot-ai2) to access the session using Big Blue Button. The online session will be available by 6pm, with the talk starting at 6:30pm. Unfortunately, Firefox tends to not work as well as Chromium based browsers.

**This talk will show how to build interactive agentic systems using Python and three powerful tools: (1) Google's Agent-to-Agent protocol for communication between AI agents, (2) Anthropic's Model Context Protocol for connecting agents to external tools and data, and (3) Gradio for quickly prototyping interactive web frontends for agentic workflows.**
**Don't hesitate to pass this information around to whomever you think may be interested to hear and discuss all things Python.**
