CPython, Grumpy, PyPy - When, How, Why?`

Performant python, Intermediate


I will talk about the differences between the three implementations. Focusing on use cases in which each of them should be used and how each environment tackles performance issues (GIL, just-in-time and Goroutines). I will also evaluate performance impact in real life scenarios.


I'll be going over each of the implementations (CPython, PyPy, Grumpy) and talk a bit about the way their implemented (GIL, JIT, GO) and show performance examples. I will show performance demos head to head and give a detailed description of when each should be used.
