I learned this nice syntax from a tweet yesterday:

    >>> import datetime
    >>> now = datetime.datetime.now()
    >>> f"Today is {now:%m/%d/%Y}."
    'Today is 01/20/2021.'

No need for now.strftime() in simple string output!

I love this - didn't realize it was a thing at all! If anyone is curious, this works for any type in Python that implements __format__ ({now:%m/%d/%Y} is equivalent to {now.__format__('%m/%d/%Y')}), and you can (ostensibly) make the format string mean whatever you want.

While I really do like this, I cannot avoid remarking that python starts to look more and more like perl

Thank you! This was literally what I opened the article for (I'd seen the f syntax previously but hadn't paid much attention) and it's conspicuously missing!
