Questions

1. How do you extract a vector of i32 integers from a PyDict struct?
2. If we have a vector of strings but we apply a .extract::<Vec<i32>>()  function on it and we directly unwrap it, what will happen?
3. How would you be able to loop through a Vec<i32> vector, doubling each item and packaging the results in another vector in one line of Rust code?
4. If we acquire the Python GIL to create a PyDict struct, will this affect the Python system in any way?
5. Although our Python classes built in our Rust code essentially run the same way as our pure Python classes, there are some core differences. What are they?
