In this tutorial, you’ll build a URL shortener with Python and FastAPI. URLs can be extremely long and not user-friendly. This is where a URL shortener can come in handy. A URL shortener reduces the number of characters in a URL, making it easier to read, remember, and share. By following this step-by-step project, you’ll […]

May 20, 2022 58m Would you like a way to send structured serialized data between different platforms and languages? What if the data was self-documenting, could automatically generate Python code, and would validate itself? This week on the show, Liran Haimovitch talks about protocol buffers and communicating with microservices through Remote Procedure Calls (RPC). Protocol […]

Python is famous for coming with batteries included, and many sophisticated capabilities are available in the standard library. However, to unlock the full potential of the language, you should also take advantage of the community contributions at PyPI: the Python Packaging Index. PyPI, typically pronounced pie-pee-eye, is a repository containing several hundred thousand packages. These […]

Have you been wondering how scopes and closures work in Python? Maybe you’ve just heard about object.__closure__, and you’d like to figure out what exactly it does. In this Code Conversation video course, you’ll use the debugger Thonny to walk through some sample code and get a better understanding of scopes and closures in Python. […]

Data scientists spend a large amount of their time cleaning datasets so that they’re easier to work with. In fact, the 80/20 rule says that the initial steps of obtaining and cleaning data account for 80% of the time spent on any given project. So, if you’re just stepping into this field or planning to […]

Dealing with errors and exceptional situations is a common requirement in programming. You can either prevent errors before they happen or handle errors after they’ve happened. In general, you’ll have two coding styles matching these strategies: look before you leap (LBYL), and easier to ask forgiveness than permission (EAFP), respectively. In this tutorial, you’ll dive […]
