How do I use python to remove duplicates in a string, and return it's number?
Write a function called remove_duplicates which will take one argument called string. This string input will only have characters between a-z. The function should remove all repeated characters in the string and return a tuple with two values: A new string with only unique, sorted characters. The total number of duplicates dropped. For example: remove_duplicates('aaabbbac') => ('abc', 5) remove_duplicates('a') => ('a', 0) remove_duplicates('thelexash') => ('aehlstx', 2)
