Episode notes
Customize The Python REPL Carefully
- Use a Python startup file to customize REPL behavior and key bindings.
- Consider pyrepl-hacks for portable shortcuts but beware private underscore modules may change.
Polars' Lazy Execution Advantage
- Polars uses lazy evaluation and chaining to optimize queries and memory use.
- This lazy execution often yields big performance advantages over pandas for large data.
Fake Data Saved Hours
- Christopher Trudeau kept a large spreadsheet of Simpsons characters with relationships for testing.
- He wished he had used Faker to generate similar fake data in minutes instead of hours.
