Question

1. Write function words() that takes one input argument—a file name—and returns the list of actual words (without punctuation symbols !,.:;?) in the file.

>>> words('example.txt')

['The', '3', 'lines', 'in', 'this', 'file', 'end', 'with', 'the', 'new', 'line', 'character', 'There', 'is', 'a', 'blank', 'line', 'above', 'this', 'line']

Answer 1

def cleanString(s):
        result = ''
        for c in s:
                if c not in '!,.:;?)':
                        result += c
        return result

def words(fileName):

        with open(fileName) as f:
                lines = f.readlines()
                result = []

                for l in lines:
                        for w in l.strip().split():
                                w = cleanString(w)
                                if w != '':
                                        result.append(w)

                return result

print(words('data.txt'))
