I don't know how efficient it is, but it's fairly clean:
clean_string = ''.join([c for c in some_string if c in
string.ascii_letters])
If you just want to do the detection, you can do
if [c for c in some_string if c not in string.ascii_letters]:
print "hey, something's bogus!"
else:
print "doing stuff with a the valid string %s" % some_string
which takes advantage of the fact that an empty list is considered a
False condition.
