List comprehension are a python/programming term.  They allow one to make a
list without generating a blank one and appending to it. A very basic
example:

newlist = [item for item in spam(eggs)]

is the same as

newlist = []
for item in spam(eggs):
    newlist.append(item)

If you walk through the code from earlier, you can see where a list
comprehension saved some lines and made the flow easier to read.
