PYCON UK 2025: exec putting Python in your Python so you can code while you code, David Asboth
Did you know you can run Python code within Python itself? In this talk, we explore how you can dynamically generate, and run, Python code using exec and why you might want to do it in the first place.
An often overlooked feature of programming languages like Python is the ability to dynamically generate and run code within an application. How can you do this? Why would you do this? We'll explore some use cases and some of the methods for doing this with built-in functions like exec. It's a useful feature to know and sometimes the right solution to a problem! We'll also discuss some best practices to avoid problems with running arbitrary code.
