Suggestions from a student to improve the reference sheet

I like both, especially the second one would be quite easy to fix (or we could make it clear that we will not test that in the midterm). For the first one, I think ideally we would give them access to a prompt somehow so that they could read all the function references and test some bits and pieces of code

1. Include the input parameter(s) as well as their type(s) for each function, similar to how it would be shown in a function's documentation (when we use the ? in Python). This will help prevent small mistakes such as messing up the order of arguments, inputing the wrong types, etc.

2. Include more import statements for common packages used in this course. I think that memorizing import statements is not the main focus of the course, and especially since some import statements can be quite long, it would be really helpful to not have to spend time memorizing strings of text.
