How can I remove multiple occurrences from a string in python?

Question

I have a string like 'AABA'. I want to remove multiple occurances by removing others. The result should be 'AB'. Sample Input: AABA Sample Output: AB

Do you want to remove duplicate characters? Try adding another example. — Diptangsu Goswami, May 25 '19 at 07:18

If the order doesn't matter, use a set.

word = "AABA"
new_word = "".join(set(word))

If the order DOES matter, use an Ordered Dictionary (from collections library).

from collections import OrderedDict

word = "AABA"
new_word = "".join(OrderedDict.fromkeys(word))

EDIT: Consult the link posted in the comments above - it gives the same advice, but explains it better.
