๐ง What Python Caches โ and What It Does Not

Learn how Python caches objects and understand its memory behavior to optimize your code
Action Steps
- Explore Python's object caching using the `id()` function to check for identical objects
- Run a test using `a = 1; b = 1; print(id(a) == id(b))` to see if small integers are cached
- Configure a test for string interning using `a = 'hello'; b = 'hello'; print(id(a) == id(b))` to check if identical strings are cached
- Test the caching behavior for larger integers and floats using `a = 1000; b = 1000; print(id(a) == id(b))`
- Apply this knowledge to optimize your code by reusing cached objects where possible
