io.open() is quite slow in 2.6, although the performance issues are fixed in 2.7 (and in 3.1). io.open() is much stricter in what types it accepts and emits. Files opened in text mode, for example, will return unicode strings when reading and will only accept unicode strings for write(). (similarly, files opened in binary mode will only accept bytestrings for write()) Regards Antoine. -- http://mail.python.org/mailman/listinfo/python-list
