"Go(lang) to Python [EuroPython 2019 - Talk - 2019-07-12 - Osaka / Samarkand] [Basel, CH] By Stefan Baerisch Python and Go are a great combination. Like Python, Go is easy to learn, powerful to use and has many useful libraries. Go and Python work great together: Go has better performance and parallelism, while Python is more expressive. Wouldn't it be nice if you could combine the benefits of Go and Python in one program? This talk shows you how. Why you may want to attend Extension modules written in C/C++ or other languages are one of the major strength Python. Go is a useful language to extend Python. This talk explains to you how to implement extension modules in Go. Content of the Talk The talk shows how to use CGO to make Go code available as a C library and then to use Cython to make this library available as a Python extension module. We start by building a wrapper for simple Go code that adds some numbers and returns the results. This program is our end-to-end example to demonstrate the steps necessary to create a Python extension module in Go. Next, we move to more complex use cases. We look at different ways to share complex data and to use Python callbacks from Go. Then, we see how to how to handle Go's Garbage Collector when exposing with Go Objects. Finally, the talk goes into the advantages and disadvantages of Go as an extension language for Python. We also look at some of the alternative ways to make Go code available in Python. Recommended Prerequisites To get the most out of the talk, you should know about the difference between native Python modules and extension modules written in other languages. Some background on concepts like garbage collection, stack and heap, and dynamic/shared libraries are beneficial. Knowledge of the Python C API is not required. You do not need to know how to write Go code to follow the talk - the talk explains all the required Go.

"Static Typing in Python EuroPython 2020 - Talk - 2020-07-23 - Microsoft Online By Dustin Ingram Python is well-known as a programming language without static types. This means that you don’t need to say what a given variable will hold, or whether your function will return a string or an integer (or sometimes one, and sometimes another!). This has historically made Python a very flexible and beginner-friendly language. In this talk, we’ll discuss the advantages and disadvantages to a static type system, as well as recent efforts to introduce static typing to Python via optional “type hints” and various tools to aid in adding types to Python code. We’ll see what this means for Python, for Python programmers, and what the future has in store for Python’s type system.

"Developing GraphQL API in Django using Graphene EuroPython 2020 - Talk - 2020-07-23 - Brian Online By Nisarg Shah GraphQL technology has become popular nowadays. While developing REST APIs, there are many things that developers need to take into consideration. There are multiple endpoints and over-fetching is the main problem of REST. GraphQL offers a unique approach and architecture for developing APIs. How is that efficient? While using GraphQL, a client can request the data which is needed. It is an alternative for building APIs in place of REST. It’s a query language that can work as a medium between the frontend and backend. The journey to develop GraphQL APIs in python needs some requirements and knowledge. We will be building APIs in the Django framework using a graphene library which includes many features of GraphQL such as ObjectTypes, Queries, Mutations, etc. We will start by understanding these concepts followed by some code. This includes detailed information about the Query class, what are resolvers, and where to write business logic, how pagination can be incorporated with queries would be included. Also, it will include the information about the Mutation class, arguments needed for mutation, and what type of response can be returned on successful operations. Learning outcomes would be the understanding of code and building GraphQL APIs using graphene in a proper and structured way.

"Writing Zenlike Python EuroPython 2020 - Talk - 2020-07-23 - Microsoft Online By Jason McDonald There's a profound gap between working code and Pythonic code. To the developer whose first language is NOT Python, the distinction can appear blurry, even arbitrary. What is this ""one obvious way"" all those Python nerds are going on about? Most of us are familiar with the ""Zen of Python"", Tim Peters's legendary, if tongue-in-cheek, set of guiding principles for the Python language. But can they actually inform Pythonic code? In this talk, Jason C. McDonald will unpack how the twenty principles (including the unwritten rule) of the Zen can guide you to write beautiful, maintainable code, by treating Python AS Python! This talk is intended primarily for developers who have come to Python from another language, no matter their experience level. McDonald will shed light on how to work WITH Python's type system, statements, and iterative tools, rather than against them. You'll walk away with a new appreciation of the language, and an understanding of what Pythonic really means; an understanding which will empower you to find the One Obvious Way to solve any problem in Python.

"Extending HTTP for fun and non-profit EuroPython 2020 - Talk - 2020-07-23 - Ni Online By Roberto Polli Writing API guidelines is a best practice for standardizing APIs produced by thousands of service provider, but what happens when those rules are not backed by internet standards? This talk proposes an iterative strategy for identify and standardize inside IETF key features of your API guidelines. The steps includes feature landscaping, stakeholder identification and engagement, prototyping and writing an actual internet-draft. The strategy is shown using two examples: - rewriting of codeDigest/code header RFC3230 adding clarifications useful for implementors; - proposing new codeRateLimit/code headers and engage with implementors (Microsoft, Red Hat, Kong, ..).

"Django Testing on Steroid: pytest + Hypothesis EuroPython 2020 - Talk - 2020-07-23 - Brian Online By Bojan Miletic The talk should hopefully provided value to all listeners, regardless of their knowledge level, but preferably you have some knowledge of pytest test parametrization We'll use a simple Django project, setup initial tests using pytest with some parallelization in the opening part and afterwards start extending them with Hypothesis. We'll go over the details, how you can use them to detect edge cases, extend test coverage and if time allows it how you can use them to test django models.
