Again, strange concept for a list. Yes, there are examples of Python (mis)using operators like "%" for string interpolation. Note the difficulties that caused; we now have 3 ways to interpolate. It looked cool at the time, but happily we have f-strings now. > L += var > and > L = L + var > > are different, so it seems to me they were not meant to be > bound together. > One is mutation, the other isn't, but aside from that, the result is equivalent. > If the intention is to insert an element, indeed it is confusing, for > me at least: > > L[0:0] = "bb" > -> ["b","b","aa"] > Thats, like, just your opinion, Man. Kidding aside, I think you'll find it's natural once you get used to slice assignment. The slice assignment iterates over the right-hand argument and inserts each element. It overwrites the existing slice if any. In this example, you've mixed issues. It looks like you've gotten confused by string iteration. When you loop a string, you get 1-len strings.
