That's actually one of the things that first surprised me about Python,
that you can actually say "is not" in a programming lan

I did try it, but I was still hoping for an explanation, which I've also
gotten from you guys, some in nicer terms than others.

It makes sense because a slice IS a list, so you should assign a list
to it. Yours is just a special case in which the target slice has a
length of zero. It's still a list, just an empty one:
>>> L = [1,2,4]
>>> print L[2:2]
[]
As for your question, yes:
>>> L = [1,2,4]
>>> L[2:2] = [[3]]

Yep.
It's a strong-typing thing. Slices of lists are lists, and
therefore what you assign to one has got to be a list,

Because a slice represents a list - even if it is a one-elemented one. So,
replacing it you need another list

I'm still a little confused about this. If what I'm inserting is just an
integer, why wouldn't
L[2:2] = 3
work? What if you wanted to insert an actual list into that slot? Would
you have to wrap it in double brackets?

Actually, I was trying to figure it out with the slice technique
instead. But yeah, as Christopher's example showed, it's not hard. But I
didn't realize you had to assign a list item to
from the Library Reference:s.insert(i, x)
same as s[i:i] = [x]

Let me apologize in advance for what I'm sure is an achingly simple
question, but I just can't find the answer in either of my Python books.
I've tried a few tests with the interactive prompt, but they don't work
either.
All I'm trying to do is insert an item into a list, like so:
L = [1, 2, 4
17 matches
