PyGrunn 2023: modern python through fastAPI and friends - Sebastián Ramírez
(One of my summaries of the May 2023 Dutch PyGrunn conference). Sebastián Ramírez ("tiangolo") has created fastAPI (and other open source projects). He talks about modern python. With modern python he means 3.7+. One of the new items: f-strings, formatted strings. f"Hi {name}". Type annotations, type hints. We've been working without type annotations all this time, so why should we add them? Well, for instance for great editor support. Suddenly the editor's autocompletion is way better. If the editor knows some variable is a string, it can offer autocompletion for the variable by showing string's methods. You also get better errors in your editor when multiplying by something that can also be a None, for instance. Type annotations are used a lot in fastAPI. @app.get("/recipes/{name}") as a decorator on a view function and a type "string" on the name argument and you get autocompletion. And type checking in the fastAPI api with automatic input validation. And you get data conversion: a ?quantity=2 in a URL is basically a string. But fastAPI knows it should be converted into an integer. Typer is a library for using the same functionality for command line interfaces. Including tab completion. A tip: use rich to … -
PyGrunn 2023: software design tips for lazy people - Arjan Egges
(One of my summaries of the May 2023 Dutch PyGrunn conference). Arjan Egges runs the ArjanCodes youtube channel. "Software design" often sounds like "huge diagrams with lots of arrows". Sometimes software design is complicated, like determining what the customer actually wants. Or a big change in your mayor concept. Or fitting together completely different technologies, especially when they are opinionated. What you also hear... "the code works, I don't have time for refactoring". "I have deadlines, and it works, so I don't have to write tests". "I just ask chatgpt to clean my code". His main point: software design is about consistently taking slightly different decisions while you're coding. These decisions compound and should make you code faster and better. He has seven tips for us: Name wisely. This about categorising things. Being clear about what it is. Even better: a good name makes sure you yourself knows what something is :-) If you cannot find a good name for something, perhaps you should approach the problem in a different way? Perhaps you should turn your class into a couple of functions. If a function has "and" in the name: perhaps it should be split into two separate functions. If … -
PyGrunn 2023: frontend for backenders ("twinspark") - Alexander Solovyov
(One of my summaries of the May 2023 Dutch PyGrunn conference). Single page applications (SPA) suck! Stop building them! (He worked on them for the last 12 years :-) ) The promises of SPAs: UI is a function of the state. A unified API for UI and native apps. Nice composability. Better long-term maintentance. And faster development because you can split in backend and frontend teams. 6 years later... 2.5MB minimized javascript. Page speed perfomance sucked. The negative side of SPAs: Performance is bad. Complexity is through the roof. Display logic in your app logic. Business logic creeps into your clients. The codebase is split. And the tech split makes people feel helpless. The backenders are excluded from the frontend so they just start to care about the API. The frontenders complain about the unusable API that doesn't care about the frontend... Back to jquery? Never. It takes only two years instead of six years for your code to go bad. Composability doesn't even exist as a word in jquery. Logic spread out everywhere. We need a modern interactive site. What do we actually want? Composability. Understandability. Server-side html rendering and a minimum of javascript. Empowered backend developers. He demoed … -
PyGrunn 2023: FastAPI with Django - Ivor Bosloper
(One of my summaries of the May 2023 Dutch PyGrunn conference). Ivor works for dacom, a GIS and agri company. They use both django and fastAIP. FastAPI is a relatively new web framework for building REST APIs. The ingredients are pydantic, data validation based on python type hints, and starlette, an asgi async toolkit. With pydantic you can define classes/models of your data. With python type hints. Pydantic takes care of the type checking and also converts the input to the correct type. With Django, you'll get the correct type out of the database, but it won't automatically fix up the model you're instantiating yourself. He showed a simple django app with two models ("Farm" and "Field"). Right next to it he generated a fastAPI app. In the asgi.py file he hooked up django as usual and added a fastAPI app to the router. So django and fastapi run side by side. He showed the django admin, running as usual, and /api/ with the fastAPI functionality. He uses fastapi-utils for a "DTO", data transfer object. fastapi-models has an APIModel class to map pydantic models to models in some other system. In this case django's ORM. Seemed to work like a … -
PyGrunn 2023: optimization for mere mortals - Dulaj Disanayaka
(One of my summaries of the May 2023 Dutch PyGrunn conference). Mere mortals? There are two kinds pf people in the world: those that like to optimize and those that are mere mortals :-) He'll try to get us over to the optimization side. Python is pretty slow. It is getting faster and faster all the time, though. And speed isn't everything: readability and maintainability are also important. And a large community. Optimization at the language level will be talked about in the "python under the hood" later during this conference. Something you often hear: Premature optimizaton is bad. Worrying about efficiency in the wrong places and at the wrong times is a real problem accourding to Donald Knuth. Micro-optimization is bad. But... is that so? A small part of your code might be called lots of times. Have you profiled it? Look at the ROI (return on investment). Time spend optimizing code that isn't the actual problem is time that is wasted. Time spend on slow code that is called a lot, that's a good thing. What he's suggesting is what he calls opportunistic optimization. It is a bit like the "boy scouts' rule": make the code a little … -
PyGrunn 2023: your API on-the-fly - Jan Murre
(One of my summaries of the May 2023 Dutch PyGrunn conference). API on the fly? The talk is about autogenerating APIs using "Amsterdam Schema". Jan works for datapunt Amsterdam, a project for being transparant as the city of Amsterdam. Your citizens pay taxes, so they have a right to access the open data that the municipality maintains. They have api projects for many datasets. Like "BAG", the official building database. Or a list of the power sockets for the weekly markets. Lots of geographical information. They use postgres, docker containers, ubuntu, python + django + djangorestframework. Developed specific for this project: django gisserver. DSO, digitaal stelsel omgevingswet, is a Dutch API specification for this kind of data. The various sorts of data are all specified in a json format that they call Amsterdam Schema. All data sets are available as geographical layers. They have a custom django management command (import_schemas --create-tables) to read such a json schema file and create the empty tables in the database. He demonstrated (live) how it works. The data was in the dabase and a nice swagger-like page was shown in the website with the option to browse the REST API. There's even support for … -
PyGrunn 2023: python under the hood, why slow and how to speed it up - Mike Huls
(One of my summaries of the May 2023 Dutch PyGrunn conference). You might get the question "why do you use python, isn't that a slow language"? Well, it is slower than many other languages, but not that slow. You should also look at programmer productivity. You wouldn't write an operating system in python. You also wouldn't write a web framework in C. How python is designed Python is dynamically typed instead of statically typed. This makes it easier for humans to understand and quicker. It makes sure you don't have to deal with many low-level details. But it can cause errors. Python is interpreted instead of compiled. If you compile code, it turns your program into machine code. The compiler has nothing further to do with it. With an interpreter, the interpreter is actually running your code when you run it. So the interpreter can handle all the OS-specific optimizations. "Live". There's byte code caching, so it's not that it does double work. In a compiled language, variables are stored in a fixed location in memory. If you give a variable a new value, that new value is stored in the same memory location. In python, everything is stored as … -
PyGrunn 2023: testing files like a pro ("faker-file") - Artur Barseghyan
(One of my summaries of the May 2023 Dutch PyGrunn conference). You might need files for testing. Real test files are perhaps not available when you need it. Synthetic data might just do fine for most use-cases. Real data might not even be allowed due to privacy concerns, for instance. You could use Faker to generate fake names and adresses and so for your test. You have control over what you generate. faker.zip_code(), faker.company_email(). Faker helps when you need to generate separate fields. But sometime you need actual files. For that you can use faker-file. faker-file works with Faker and factory_boy. It is added as a "faker provider". It supports text, csv, docx, mp3, png, pdf, epub, etc, etc. Also .eml email files. You can have it generate random text, but you can also pass sample text. You can also pass a template: you can use Faker's regular methods like first_name and address in there. Handy! If you generate a png, it will be a png with a bitmap of the text. A zipfile with some folders and docx files is also possible. And zipfiles with folders and zipfiles with pngs in them. So: basically everything. Normally, the files are … -
Hurray, this friday there's PyGrunn again
Hurray, this friday (23 May) there's the 11th installment of the Dutch PyGrunn conference. Time to wake up again at an early hour to grab the train to the north of the Netherlands :-) Oh, and to dig out a historic legendary pygrunn t-shirt (I've chosen the 2012 one). I really enjoy these conferences. There is a nice mix of talks to choose from, from python inner details to how-we-use-it. Here are four that I'm looking forward to: Combining fastAPI and Django. At our company we're using fastAPI for a new project, but all our existing projects are in Django. I hope to get a better feel for the (im)possibilities. Personally I haven't used fastAPI, so a conference like pygrunn helps a to broaden my knowledge. Sebastián Ramírez, the creator of fastAPI, gives the closing talk so that'll be a good source of information. And... Sebastián's talk might also be a good source of a "mental model", a way of thinking about software and software design and projects. He'll talk about how to make code that is less error-prone, simpler, more efficient, and have a great developer experience, all at the same time. And all this while including best practices … -
