That may be partly due to Python's not-so-good facilities for implementing the "exceptional return value" method. To be fair, plenty of other languages have similar shortcomings and it's mostly in more recent languages that the problem has really been recognized, and addressed with features like option types. -- http://mail.python.org/mailman/listinfo/python-list
