PyData Prague #19 - Pandas in Heaven

Hello data embracers!

The 19th Prague PyData meetup will take place at ČSOB. As usual, the talks will start at 18:30 but we encourage you to come as soon as 18:00 to enjoy the opportunity to socialise and refresh yourselves (which you can continue doing during the break and after the talks).

Our main goal is to build the community around Python and data and make it welcoming to people of various skills and experience levels.

⚡ If you are interested in giving a lightning talk (up to 5 minutes to present an idea, tool or results related at least to some degree to Python and/or data), please contact us before the event or at its beginning.

📢 Big Bank Data in Migration: From In-House CSV to Parquet in Amazon S3
(Jakub Kramata, ČSOB)

What is it like to migrate data from on-prem systems to the cloud in one of the largest banks in the Czech Republic? How to check that nothing has changed along the way? Join us to discover our Python-based solution! Not only will we go through the code, but we'll also focus on the pitfalls, challenges, and hardships we have encountered along the way. We will thoroughly explain how we verify the migrated data, which is exported as CSV from the source system and stored as Parquet in the AWS Data Lake. Expect a candid and emotional presentation with thoughtfully named commits.

📢 Pandas Roadmap and Beyond

Discover the essence of Pandas Enhancement Proposals aka PDEPs and their impact on the landscape of data analysis with Pandas. Join us for an overview of proposed changes, aimed at addressing corner cases and inconsistencies that have emerged over years of development, presented by one of Pandas' core contributors. From banning (up)casting in "setitem-like" operations to reevaluating inplace option in methods, delve into the behavioural shifts shaping the Pandas roadmap. Gain insight into the evolving copy and view semantics of operations, offering a glimpse into the anticipated Pandas 3.0 experience by overviewing changes in the new version.
