Can someone explain what translate() and maketrans() do in python?
E.g. line = line.translate(line.maketrans('', '', string.punctuation))
Confused to what they do exactly.

maketrans () can have 2 or 3 arguments.
In your example, you have 3 arguments, but it might not be obvious because 2 single quotes can look like one double quote.
The first argument is an empty string that is delimited by single quotes. The 2nd argument is identical. So, the primary use of the maketrans () method is being skipped over because there is nothing to translate.
The 3rd argument contains every punctuation character so that specifies characters to remove from the object of the translate () method, which is <line>.
So, the overall effect is to remove punctuation characters from <line>.
