Many languages follow the syntax of C, and use semicolons to indicate the end of a statement. For example, in JavaScript:

When Lambda@Edge first came out, I added it to my blog’s CloudFront distribution in order to add security headers. Then, when Lambda@Edge added Python support, I converted my function from JavaScript to Python.
Black is the de facto standard code formatter for Python, and these days I use it on all my projects. blacken-docs is a tool that also allows you to apply Black to code samples in your docs. I recently rolled it out on my projects to great effect.
I started this blog in 2014 using the popular Jekyll. Whilst it served me well, I’ve wanted to migrate to a Python-based tool for a while now, for a few reasons:
Writing type hints gives us some familiarity with the typing module.
But Python also includes the similarly-named types module, which can also come in handy.
Let’s look at the history of these two modules, some use cases of types, and one way in which it’s not so useful.
Python’s re module lets us search both str and bytes strings with regular expressions (regexes).
Our type checker can ensure we call re functions with the correct types, thanks to some parametrized classes.
