I have a list of lists:
[[12, 'tall', 'blue', 1],
[2, 'short', 'red', 9],
[4, 'tall', 'blue', 13]]
If I wanted to sort by one element, say the tall/short element, I could do it via s = sorted(s, key = itemgetter(1))
.
If I wanted to sort by both tall/short and colour, I could do the sort twice, once for each element, but is there a quicker way?

A key can be a function that returns a tuple:
Or you can achieve the same using
itemgetter
(which is faster and avoids a Python function call):And notice that here you can use
sort
instead of usingsorted
and then reassigning:
