for c in some_string:
if c not in string.ascii_le tters:
raise ValueError("Non-ascii value!!!")

Instead of raising an error, you can take whatever action you prefer:

for c in some_string:
if c not in string.ascii_le tters:
print "Character '%s' is non-ascii." % repr(c)

Or turn it into a function:

def isascii(s):
for c in some_string:
if c not in string.ascii_le tters:
return False
return True

see:

eg. ord(max(string) ) < 128 ( Scott David Daniels ).

"äöü".decode ("ascii")

should do the trick -- you get an UnicodeError when there is anything ascii
can't encode.
