Lastly, an important application of strings is thesplitmethod, which returns a list of all the words in the initial string and it automatically splits by any white space. It can optionally take a parameter and split the strings by another character, like a comma or a dot 4. Formatting str...
We split the line into words. The\Wcharacter class matches any character which is not a word character. for w in fields: if w and not w.isdigit(): words.append(w) We skip empty fields and verse notations (they contain digits). c = collections.Counter(words) common = c.most_common(...
