Here's a quick demonstration of how to format your text in Courselets: this is italics; this is bold.
You create a new paragraph by typing a blank line before it. You can create a bullet list by typing new paragraphs that start with an asterisk and a space, like this:
* this is the first bullet. * this is the second bullet.
You can create a numbered list by typing new paragraphs that start with a number, period and a space, like this:
1. this is the first item. 2. this is the second item.
You write a code block by ending the previous paragraph with two colons, and indenting each line of the code block like this:: def cool_function(a, b, c): return b * b - 4 * a *c
