That's right. > My question is why is this and is there any way to make c local to list > comp? It was a design decision that is now regretted. There is no way for you to make it local to the list comp except to wait for a new version of Python that behaves in the way you want. Or you can look at generator expressions, which are written just like list comprehensions except with round brackets (). They are not quite the same thing, but you can often use one in place of the other. -- Steven. -- http://mail.python.org/mailman/listinfo/python-list
