01Which of these returns None instead of a sorted list?
Hint
There's a Python convention: in-place operations don't return the object.
02What is b"abc"[0] in Python 3?
Hint
Slicing returns the same type, but indexing one element of bytes is special.
03Why is dict.fromkeys(items) often the modern way to dedup a list while preserving order?
