After some trial and error with the interpreter, I found this:

st = """`'Tis so,' said the Duchess: `and the moral of that is--"Oh,
'tis love, 'tis love, that makes the world go round!"'""" # notice the
starting and ending triple quotes, just to avoid all the backslashes and
the ambiguities with quoting characters ;-)

wordlist = [thisone.strip("""'",!` :-""") for thisone in st.replace('"',
" ").replace("-"," ").split()]

I don't know if you read the chapter regarding "list comprehensions" in
your tutorial, but this is one of those. First of all, I replace all
double quotes " and dashes - with spaces:
st.replace('"', " ").replace("-"," ")
then I use split() to divide the long string in a list of almost-words.
At the end, with the for clause in the list comprehension, I strip all
leading and trailing non-letters (again, I enclose them in a
triple-quoted string) from each of the elements of the list.

In the end, I have wordlist:

['Tis', 'so', 'said', 'the', 'Duchess', 'and', 'the', 'moral', 'of',
'that', 'is', 'Oh', 'tis', 'love', 'tis', 'love', 'that', 'makes',
'the', 'world', 'go', 'round', '']

hello Franceso,

Still im grazy wht with you and Joel the strip works and with me I get errors.

But how can I use the triple quotes when reading a textf-file ?
