We dive deep into the popular packages and software developers, data scientists, and incredible hobbyists doing amazing things with Python. If you're new to Python, you'll quickly learn the ins and outs of the community by hearing from the leaders. And if you've been Pythoning for years, you'll learn about your favorite packages and the hot new ones coming out of open source.","last_synced_at":null,"page_url":"https://stenobird.com/podcast/talk-python-to-me"},"episode":{"title":"#539: Catching up with the Python Typing Council","slug":"539-catching-up-with-the-python-typing-council","published_at":"2026-03-06T16:58:04+00:00","page_url":"https://stenobird.com/podcast/talk-python-to-me/539-catching-up-with-the-python-typing-council","show_page_url":"https://stenobird.com/podcast/talk-python-to-me","url":"https://talkpython.fm/episodes/show/539/catching-up-with-the-python-typing-council","audio_url":"https://talkpython.fm/episodes/download/539/catching-up-with-the-python-typing-council.mp3","summary":"Learn how the Python Typing Council standardizes type annotations to prevent tool inconsistency.
