We are organizing the the sixth edition of PyDay in Barcelona!
PyDay is an event full of FREE python-related workshops and activities for the Python community, organized once per year. Over the last five editions, PyDay has become a great opportunity to share our love for Python and engage users, companies and newcomers into it!
PyDay BCN 2022 will have different thematic tracks –e.g. data science, web development, security– with hands-on workshops of about 90 minutes in which participants will learn how to use different libraries, tools and techniques, fully guided by members of the community and support volunteers.
Participate in Kahoot and win prizes!
We will host a Kahoot game with questions about PyBCN and Python in general, with prizes for the fastest players. Will you miss it?!

How many ants can carry an elephant? Pushing the limits of AWS Chalice
Kemalcan Bora
Sala Hipàtia d'Alexandria Language: English Topic: Serverless apps Python level: Beginner Topic level: Beginner
Chalice is a framework for writing serverless apps in python. It allows you to quickly create and deploy applications that use AWS Lambda. Serverless applications generally have some limits like RAM, storage, and CPU.. and the main purpose is simple functions like login, registration, etc. So what if we want to create an ML application? How can we handle our limits? don’t panic young Skywalker. We have to push our limits and we’ll install NumPy, and Sci-kit learn libraries and our app will roam freely in the cloud in peace.
Requirements:
Python, AWS account, AWS chalice framework

Antonio Molina Garcia-Retamero
Sala Hipàtia d'Alexandria
Language: Spanish Topic: Observability Python level: Beginner Topic level: Beginner
Observability is key in distributed systems and it is gaining importance within the industry. So it is important to understand the concepts behind the idea of observabiity and why is important to us, as developers, to make our developments “observable”. Being able to create software that is easy to debug while systems scales and complexity grows will level up us as developers and will make our clients and employers far happier. This is what this workshop is about. From a brief theory of what observability is to some practices and best practices.

Using Numba Effectively Today
Cheuk Ting Ho
Sala d'actes Ada Lovelace Language: English Topic: Data Science Python level: Intermediate Topic level: Intermediate
Numba is syntactically easy to use - just add a decorator, but actually very hard to use effectively. The reason being it is difficult to understand what Numba does to speed up the numeric operation. This workshop will provide all the knowledge that you need to make Numba works for you.
Requirements:
This workshop is for Data scientists or developers who have math-heavy code that would like to speed up with the benefit of Numpy and Numba.
What is required from attendees
- A computer with a stable internet connection (useful to look up information);
- Python 3.8 or above;
- Jupyter and Numba installed (detail about Python libraries required will be announced later);
- An opened mind and ready to learn something new

Sala Hipàtia d'Alexandria Language: English Topic: Test driven development Python level: Beginner Topic level: Beginner
Nowadays software products are becoming so complex that is unimaginable that one software engineer would develop it alone without any sort of automated testing, so let’s get together to practice Test Driven Development while pair programming with the other workshop participants. We will solve some code challenges together, under a bit of friendly time pressure and changing development hats every 5 minutes. If you are interested in knowing how it all looks like then join the workshop!

Hey! I’m Pavel, but, please, call me just Pasha. I relocated just 2 years ago to Barcelona. I’m using python already for 10 years and really love the flexibility of this language. But if you’ll ask me what are my most loved programming languages, Python won’t be in my top 2. I can explain you why so after several beers in the bar. Now I’m working as a Team Leader, but I never stop writing code and practicing Python. See you on PyDay BCN 2022!
