0:00 We've come to the headline feature, the headline advantage of Python 3.11 and that's performance.
0:09 I said at the beginning that these better error messages for one of two major things.
0:14 Well, here is the second and for me, this is actually the biggest and most important change, Python 3.11 is maybe 40% faster than even python 3.10.
0:28 And for something that's been around and been maintained and improved for over 30 years to make that big of a
0:34 jump in just one year. It's incredible Guido Van Rossum, Mark Shannon and a bunch of other folks over at Microsoft as well as other core developers.
0:44 But there's a special team at Microsoft specifically focused on making CPython faster,
0:50 you know what they're called, the faster CPython team and their goal is to continue making these improvements,
0:56 these big jumps over the next couple of versions. This is really the first one that gets a big boost
1:03 from that work. So it's just the beginning, but it's really,
1:06 really exciting in this chapter. We're going to see some of the features that make this possible, but not all of them, there's a bunch of small changes in a few really big ones.
