    I decided that retirement was boring and have joined the Developer Division at Microsoft. To do what? Too many options to say! But it’ll make using Python better for sure (and not just on Windows :-). There’s lots of open source here. Watch this space.

    It's bittersweet: I'm leaving @Dropbox, and am now retired. I've learned a lot during my time as an engineer here -- e.g. type annotations came from this experience -- and I'll miss working here.

    Thank you, Guido

    Thanks for all the support (email and Twitter). I'm overwhelmed by the responses and won't be replying to most emails in person (except from core devs) but it's much appreciated. I'm still going to be around in the background!

    Python 4 FAQ. 1. The version after 3.9 is 3.10; in fact it already exists (in github master). 2. If there ever is a version 4, the transition from 3 to 4 will be more like that from 1 to 2 rather than 2 to 3.

    Today's Python history lesson: Python took its control and data structures from ABC, its identifiers, strings and %-string formats from C, and its regular expressions from Perl. But its # comments (and #!) and -c command line flag came from the UNIX v7 shell.
