2828. Check if a String Is an Acronym of Words.py

'''
Given an array of strings words and a string s, determine if s is an acronym of words.

The string s is considered an acronym of words if it can be formed by 
concatenating the first character of each string in words in order. For example, "ab" can 
be formed from ["apple", "banana"], but it can't be formed from ["bear", "aardvark"].

Return true if s is an acronym of words, and false otherwise.

        for w in words:
            res += w[0]
        return res == s
