Of course, in Python, you can slice with [start:end:step], so it is valid to do
list[:3:3]for double the happiness. Not that you'd ever practically do so.It's functionally identical to
list[0]so you could definitely just refactor your code to uselist[:3:3]I don't think that's equivalent. I think the former would return
e0and the latter would return[e0]You're right, it would return a list containing the first element of the sliced list.
So:
Well, technically a sequence containing the first element of whatever sequence you sliced. Take advantage of implementing magic methods and you too can abuse slice notation with your classes.
