Hello,
For a exerise I made this one :" import string def extract_words(s): """ >>> extract_words('Now is the time! "Now", is the time? Yes, now.') ['now', 'is', 'the', 'time', 'now', 'is', 'the', 'time', 'yes', 'now'] >>> extract_words('she tried to curtsey as she spoke--fancy') ['she', 'tried', 'to', 'curtsey', 'as', 'she', 'spoke', 'fancy'] """ word= "" s=string.lower(s) for char in s : if ord(char) >=65 and ord(char) <= 122 or ord(char)==32 or ord(char)==45: word= word + char word=string.split(word, "--") word=string.join(word, " ") word=word.replace (" ", " ") word=string.split(word, " ") return word if __name__ == '__main__': import doctest doctest.testmod() But now I wonder if this can be done more easerly ?
