Little fixes for Day 2

[akokai]

Only thought of a few really minor things so far.

• Lists: Can't seem to access the <function>? help mechanism in Jupyter for methods. Running, e.g., ''.join? just returned "Object not found" or something like that. So instead, suggesting to look up the docs on join and clarifying that it's a string method, not a list method.
• Loops: The use of loops + conditionals to "evolve" a variable iteratively needed a bit of contextualization & explanation. People were a bit mystified why anyone would do this. I suggested population modeling (ecology, etc.) as one possible reason.

One more thing:

• Lists: Added explanation of the behavior of variables created by slicing a list, when the original list gets changed. This is counterintuitive because of the mutability of lists, etc. Maybe someone should review my explanation to make sure it's not confusing.

in jupyter you have to type the datatype to get the help:

str.join?
str.split?
list.append?
list.extend?

did that work for you? but going to the docs works too, if it works, can you add the str.join? back to the notebook as a second reference?

all the other changes look great, we'll let @alexestes and @natalieahn give input, then go ahead and merge

Looks good to me!

Hah, TIL that you need to say str.join? :) Thanks, it works. I reinstated the Jupyter help thing as the primary course of action, with a link to the Python docs just to show people that all of this is also on a website you can access outside of Jupyter.

I'm still not fully satisfied with the 'population' loops/conditionals example – I have a feeling we can find a more intuitive and straightforward example of that pattern – but I'll leave it for now.

I think we can merge this whenever the intensive series is done.
