I've just started studying Python and I got a homework problem where I need to create a dictionary containg words I got from a text file. I managed to read the text from the file, remove specific characters with regex, but I'm having trouble doing the same thing with a specific character combination, like 's.

I tried using the following code on the variable text:

text = re.sub("[('s)]", '', text)

The problem with this piece of code is that it removes all the s characters in the text, even the ones with no leading apostrophe characters.

How could I make sure only s characters with trailing apostrophes gat removed?

Do not use regex if you need to replace literal text. `text = text.replace("'s", "")` will suffice. `"'s"` would also work as a regex, but there is no need to use `re.sub` here. – Wiktor Stribiżew Mar 22 '19 at 21:20
Thank you, now I see I overcomplicated this a bit. – Szelmat Mar 22 '19 at 21:21
