Integer not iterable

Not sure if this was asked before. I've been going through the Sage and Python tutorials for the past 3 weeks as I worked out that I'll eventually have to learn at least some Python so to get what I need from Sage. So far so good,

But this one escapes me. The Sage tutorial refers to this example in The Python library:

map(mul, [0, 1, 2, 3], [10, 20, 30, 40]) which is supposed to yield [0, 20, 60, 120]

However, I keep getting ... ... TypeError: 'sage.rings.integer.Integer' object is not iterable

What's causing this?

Hope someone can help Gerry

Yep, silly me, worked it out. Few lines below on the same page it says to enter the following command:

from operator import mul

Hope someone who uses the same approch in Learning sage finds this useful.

In conjunction with map() I would prefer an anonymous function (lambda function):

map(lambda x,y:x*y, [0, 1, 2, 3], [10, 20, 30, 40])
