Question

Python

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

import string


def words(filename):
    words_in_file = []
    try:
        f = open(filename)
        for line in f:
            cleaned_line = ''
            for ch in line.strip():
                if ch not in string.punctuation:
                    cleaned_line += ch
            line_words = cleaned_line.split()
            words_in_file += line_words
        f.close()
    except FileNotFoundError:
        print(filename + " is not found")
    return words_in_file


print(words('example.txt'))
