If you have a Python installation you should be able to find the "Whats New" section of the docs. List comprehensions are described pretty well in the "What's new in Python 2.0?" section. This gives some simple examples as well as the rationale behind them. Mark -- http://mail.python.org/mailman/listinfo/python-list
