 Hi again, in this lesson we're going to talk about how to see the speed of Python's code. On the website speed.python.org you have a benchmark system which can show you the speed of Python's code. This site is an authoritative source of benchmarks for all Python implementations and it's focused on real world benchmarks rather than synthetic benchmarks. On this site you have three sections. The first section is change section which tracks performance changes in the latest revisions. Second one is timeline which analyzes performance over time and the last one is comparison which compares different executables and revisions. Let's go to this last section, let's open it. Here you can check the speed of executables and see benchmarks on this chart. You can use horizontal chart if you wish and as you can see now Python version 2.7 is still the fastest Python and the latest Python version 3.6 is faster than version 3.5 and of course Python version 3.7 will be faster than version 3.6. That's all in this lesson, thanks for watching, bye.
