If your problem is over QQ then just use that (PPL supports exact
rationals).

Ok, thank you all!
I was curious just because, due to the error, I did not expect a result.

Or type
Integer = int
to make Sage integers the usual Python integers in that session.

The short answer is that mathematical objects in Sage don't define addition
by implementing __add__ and __radd__ by hand. If you want to learn about
them make sure to not add Sage objects (like Sage integers). E.g. int(1) +
y would work.

I am running the following Python example from the book "Learning
Python", from Mark Lutz and David Ascher, but Sage is returning a
TypeError after presenting the correct response. Can anyone explain me
why? I've found this very strange.
sage: class Commuter:
: def __init__(self, val):

And you can make it so that the default for the workshe
You can define a function which takes a list or tuple as an argument,
and then you can iterate through its elements, with tests if you like.
sage: def sum_elements_whose_square_is_one(x):
: return sum(a for a in x if a^2 == 1)
Then for example:
sage: sum_elements_whose_square_is_one([1,2

You can also use one of the following tricks.
- you can make a cell python by typing
%python
in the first line of the cell.
- towards the top of every notebook worksheet,
there are four drop-dow
