The situation is as follows: the company you work for is small, and you want to publish a Python package internally. However, you don’t want to pay for a service to do this or add a new tool. Although this may seem like a specific situation, we can say that it can happen quite frequently. In Brazil, literally 99% of companies are small businesses. According to Forbes, the statistic is exactly the same in the USA (the first country that appeared in the search :)). ...

Today I learned: Replace function in Django’s ORM. Sometimes we stumble across a bug or a change in the business logic that forces us to change the value of a column based on another from the same table. I thought that Django might have this solved and indeed it has through the database functions. In my case I had to update the value of a column replacing its current value and, at the same time, using the value of another column. This was possible with little code using the function Replace. ...

If some day you wondered how to inspect a HTTP request to try out some webhook or even an SalesForce outbound message (😅), I have a tip for you: requestbin + ngrok. The requestbin is an open source project with this purpose. It’s self hosted! You can run it locally using Docker or even deploy it to a free Heroku dyno. If you decide to go local, ngrok can help as well. With it you will be able to create private tunnels from your local environment, making it available to the world. ...

In this Python Drops episode we’re going to talk about f-strings, also known as Literal String Interpolation. This feature was added on Python 3.6 and the goal is making the String interpolation more readable. Interpolation is a fancy name to mount/create/construct a String from data you want to: a variable, a method return and so on. Before it, the common way to interpolate Strings looked like this: Format Strings (example from the oficial documentation) ...

The module pathlib is around since Python 3.4 but I must confess that I’ve started to use it a short time ago. For those who are listening this name for the first time, pathlib is an Object-oriented filesystem paths module; in other words, a module with few classes to help you to manipulate paths in a pratical way. Each class has a proper use and if you wanna dive into it, I suggest to take a look in the docs. This post is introductory (and at the same time, a reminder to myself :)). ...
