THanks Gabriel, Now I know about the zip function. Your explanation of Boolean ops on lists was clear. It leads to some intriguing results:
bool([False]) --> True I wonder if python 3 changes any of this? > A and B means: check the boolean value of A; if it's false, return A. > Else, return B. > A non-empty list has a boolean value of true, so the second list is > returned. > > If you want an element-wise operation: > A = [False,True] > B = [True,True] > result = [a and b for a,b in zip(A,B)] > -- > Gabriel Genellina -- http://mail.python.org/mailman/listinfo/python-list
