Ignore leading '>>>' and ellipsis?

[Reckoner]

Hi,

I am studying some examples in a tutorial where there are a lot of
leading >>> characters and ellipsis in the text. This makes it hard to
cut and paste into the IPython interpreter since it doesn't like these
strings.

Is there another interpreter I could use that will appropriately
ignore and interpret these leading terms?

For example, I cannot paste the following directly into the
interpreter:

>>> d = dict(x.__array_interface__)
>>> d['shape'] = (3, 2, 5)
>>> d['strides'] = (20, 20, 4)

>>> class Arr:
...     __array_interface__ = d
...     base = x
