One of the delights of coming back to Python in an intensive way after many years is some of the new ways to do the usual things that I hadn’t learned before.

In this case, I am finding the use of “f-strings” (introduced in Python 3.6, described in PEP 498) to be quite delightful.

print(f"Warning: {sys.argv[2]} exists!")

The previous syntax for format strings always slipped away from my memory, but these seem a lot stickier, and they give me a lot of freedom to just keep writing.

Python is not the greatest language in the universe, but it can allow a lot of fluency that I never experienced in other languages.
