Question

Please help if possible..the yellow section is the prompt..

This is a duplicate of the docstring: Given some strings (in any set or sequence type), filter out any non-alphabetic characters from each string, leaving only the alphabetic characters in each. Collect these simplified strings, and return a frozenset of them. HINT: You can create a frozenset, from a list, tuple, or set, using the frozenset constructor: fs frozenset ( list-of-strings) = https://docs.python.org/3/library/stdtypes.html ?highlight-frozenset#frozenset The input dataset might have duplicates; since you are returning a frozenset, duplicates will be eliminated. Likewise, if two strings start out different but are identical after filtering (such as "it's" and "its"), only one will be returned. If a string filters down into the empty string, do *NOT include it in the set to be returned.

Explanation / Answer

The answer is as follows:

def alpha_only_words(words):
    list = []
    for i in range(len(words)):
        new = ""
        word = words[i]
        for c in word:
            if c.isalpha():
               new = new + c
        if len(new) > 0:
           list.append(new)
    fs = frozenset(list)
    return fs
