[Tutor] Finding all the letters in a string?

[Andrew Nelsen]

I was wondering, recently, the most expedient way to take a string with
[@#$%^&*] and alpha-numeric characters [ie. "^@%#*$@*$g@)$&^@&^$F"] and
place all of the letters in a string or list. I thought there could be
obvious ways:

A) Find all the letters, put them in a list, one by one. Something like (I'm
not sure yet how I'd do it...):

import string
list = {}
string = "@*&^$&*^@$g*(&@$*(&$@c(*&*(&c^&%&^%"
for x in string:
    if x <is in string.letters?>
        list = list + [x]

B) Delete all the characters in the string that don't match string.letters:

No idea...strip()?

Thanks,

Drew
