I'm using the Interactive Shell.
First question: How do I get back to the working session after I'm done consulting the documentation? For example, if I look up for tan? I get all the information I need and after that a highlighted END. I just don't know how to get back to where I was before.
Second question: The last example in the section Functions, Indentation, and Counting of the Guided Tour doesn't seem to work. It's the example Class Evens(list) .... I've tried typing exactly as it is several times and I keep getting a syntax error message.
Any help would be appreciated. Thank you very much.
