In this talk, through some examples and demos of PyScript, we will see how to use it - just include the CDN URL, understand that it is a frontend-only Python that runs on the browser and learn the fact that it can work with javascript in conjunction.

After that, we will look at what is under the hood - Pyodide - which is a Python distribution for the browser. It is what is essential to power PyScript. We will discover what is the difference between using PyScript and Pyodide.

Finally, we will conclude what is already available in PyScirpt like which library you can run on PyScript and which ones are still yet to come. In the end, we will answer the question - Will PyScript replace Django?

This talk is for those who are curious about PyScript and the idea of running Python in the browser in general. We will assume no piror knowledge about it.

Details

Since the launch of Pyscript there are a lot of questions about what is it and how it works. Will it change how we do web development with Python? In this talk, we will go through what Pyscirpt actually is, and how it works (using compared Python libraries on Pyodides). We will also talk about why Pyscript is created - not to take over JavaScript or Django, but to give the rest of 99% of people access to Python.

In this talk, we will also showcase how to use PyScript with JavaScript and/ or Django, hopefully, to inspire Python web developers to try it out.

Everybody hates mundane tasks, they are boring, repetitive and time-consuming. That’s why I love building bots, they can finish my tasks for me by working 24/7. But to build a bot to interact with the users, you have to write in async. If you are afraid of async, don’t worry! Today I am telling you how I learn using async and how I avoid checking in 500+ people in a conference by building a bot with Discord.py.

In the first part of the talk, there will be a short introduction to Discord. As more and more conference goes online, it’s become a more and more popular tool among the Python community. I will also introduce Discord.py, a python library that offered an async API to let you build a Discord bot. This will give the audiences a background about the following quick demo and explanation of a simple bot that I built.

In the second part of the talk, I will walk through how to build a bot for registering attendees for EuroPython. Following a quick demo, I will also give a walkthrough about some of the async coroutines available in Discord.py: event listener like on_ready and commands. I will also explain how the async code is different from the sync code and the danger of mixing them together.

Hopefully, audiences will be inspired to build their own bot and learn a little bit about writing async code in Python and using Discord.py. This talk is suitable for attendees who got basic knowledge in Python but not necessarily know about Discord or async.
