Zhang: The reason max and min are not imported by 'from numpy import *' is because there are no such functions in numpy. They are ndarray methods now (a.max(), a.min()), there is also a maximum and minium function which behaves somewhat differently. There is still a sum function as you have discovered, and it will clobber the builtin. Another good reason not to use 'from numpy import *' -Jeff -- Jeffrey S.
