I do find this behavior quite surprising--diameter should be an alias
for either relative or absolute diameter, not depending on the
interval.
We're just calling an upstream function, it's upstream which has this
strange convention.

You can also use one of the following tricks.

%python
in the first line of the cell.

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:

[File...][Action...][Data...][sage]
You can use the last of these menus and
change 'sage' to 'python'.
And you can make it so that the default for the worksheet is this
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:

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.

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

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