I think that like me you read 'i**2' when the OP actually wrote 'i**=2'. i**=2 will change the value of i in the conventional while loop. In the list comprehension it is of course a syntax error even if you assume list comprehensions are expanded to allow the while. -- http://mail.python.org/mailman/listinfo/python-list
