Detec nonascii in a string

[Sebastian Bassi]

Hello,

How do I detect non-ascii letters in a string?
I want to detect the condition that a string have a letter that is not
here: string.ascii_letters

Best regards,
SB.

"äöü".decode("ascii")

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

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

for c in some_string:
if c not in string.ascii_letters:
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_letters:
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_letters:
return False
return True
