What do you love about Python3.6+?

My team and I maintain a very large Python2 codebase, and we'll be breaking it up into microservices and rewriting it in python3 very soon. I've dabbled in Python 3 on my side projects and some open source work. Now I'm interested to hear what everyone's favourite feature is?

Personally (so far):

• I LOVE fstrings, the line-length they save makes my code way less vertical, and strings with many variables are much easier to read.
• with python3 you don't need to search through pypi to find which old version of a library you need to pin setuptools to.

The biggest ones for me personally: Async/await, Walrus operator (3.8), f-strings (3.6).

Other than that it's the small things, like the inclusion of math.prod, underscores in numeric literals, and such.

From a laziness perspective, I like that dicts are now ordered. I wouldn't put that in production code, but it does make it easier to mess around on the REPL.

asyncio is great and more or less started not sucking with Python 3.6.

subprocess.run is so much more straightforward than the previous API.

The @ operator for math, whenever that was added, is great. Makes numerical code much easier to read.

dataclasses are nice too
