Python has had syntax support for type annotations for a while now. The Python runtime doesn't enforce the typing at all, but it can be enforced by a linter or by your IDE. And I believe you can introspect the type annotations at runtime, because they are actually part of the syntax.
There's even an alternative way of doing type annotations through specially formatted comments, just in case you might still need to write code that is backwards compatible with Python 2.
I am of the opinion that regex for email address is a bad idea. The only two things that you need to check an email address are:
Does the address contain an @ symbol?
Is there a dot to the right of the @ symbol?
Then just try to deliver to it, and let the MTA do the rest.
Email addresses can be complicated, and there's plenty of valid addresses that can be excluded by attempts at regex validation.
@bristle Pro tip – when replying to a Lemmy thread from Mastodon, remember to tag the community (i.e. @tech) in the reply in order to ensure your reply actually shows up on Lemmy. If you don't, it won't always federate back to Lemmy.
It seems to federate without tagging when the thread OP is a native user on the Lemmy instance, and when directly replying to a Lemmy user. Still unsure exactly when it will and won't.
I want the Xenia trans rights sticker
@196 oops I forgot that it federates and makes a new post when I mention the community on Mastodon
Hi to all the cute queer people in my phone
Naming things is one of the two most difficult issues in IT, alongside cache validation and off-by-one errors.
@Zagorath I love me some spicy small-town drama.
