Hi Alice, try accessing via its class:
Poll._meta.fields[2].maxlength
This is perhaps better spelled as::
Poll._meta.get_field('choice').maxlength
However, be sure to note that (as the leading underscore indicates)
``_meta`` is semi-private and you should be prepared to accept
possible future breakage if you use it.
