Answer 1

I think it depends on the context.

1. It can be ‘ or “ when you write a string. In this case it means the chars you use to mark the begining and end of a string.

2. It can be a special char in a string that you’ll use to split it, like:

s = “element 1; element 2”
lis = s.split(“;”)
# lis is a list with 2 strings

3. It can be a special char like \ that you use to include ‘ or “ inside a string.
