Since POSIX is not supported by the Python module re

, you must emulate it using a character class.

You can use one of the regular-expressions.info and add a limit quantifier {10}

:

[\x20-\x7E]{10}

Alternatively, you can use Matthew Barnett's regex module , which claims to support POSIX character classes (POSIX character classes are supported).
