What we’re about
A monthly meetup of Python developers from Zagreb and region.
Each month, we host an event featuring engaging talks by our community volunteers, followed by a social hour with drinks. During the summer, we take a short break from formal events and instead organize relaxed gatherings, placing a greater emphasis on socializing.
If you have a topic in mind that you'd like to present at one of our events, feel free to reach out to the organizers!
To ensure a positive experience for all participants, please review the Code of Conduct.

Speaker: Franko Buneta, Data Scientist, IBM
Title: Beyond the Bamboo Forest: Pandas for the Brave and the Curious
In this session, we’ll go beyond the basics of Pandas, the most popular and widely used data science library in Python. We will dive into techniques that experienced Python data scientists can immediately apply to their daily workflows, data pipelines, and exploratory data analysis.
The focus will be on:
- Helpful Custom Methods in Pandas
• Extending the pandas API with custom accessors and methods
• Reusable patterns for common transformations
• Chaining custom methods to create cleaner, more readable pipelines - Data Lineage Using Pandas and Mermaid
• Tracking the history of transformations applied to a dataset
• Annotating DataFrames with metadata for auditability
• Simple and effective strategies to preserve lineage without leaving your Jupyter Notebook - Filtering and Updating Data with Complex Criteria
• Combining multiple conditions efficiently with boolean masks
• Conditional updates with .loc
• Handling advanced use cases such as nested logic, cross-column checks, and conditional replacements
By the end of the lecture, you’ll have a set of concrete techniques to make your pandas workflows more powerful, transparent, and efficient.
Audience:
This talk is primarily designed for experienced Python developers and data scientists who already use pandas and want to refine their toolkit with advanced patterns.--------
Join us next Tuesday at MaMa for an extra awesome talk by Franko from IBM. Drinks and discussion afterwards at Old Pharmacy Pub 🍻🍷🥤
