You named your own script file "calendar.py". As a result, when you
did `import calendar`, due to the way Python 2.x searches for modules, it
imports your file instead of the `calendar` module in the standard library,
thus leading to the above exception. Because of this sort of problem, it
is/was considered bad practice to give a module/package the same name as
any std lib module.

However, if you are running a recent-ish version of Python, adding `from
__future__ import absolute_import` may resolve the problem. See PEP 328 for
details. Absolute imports were thankfully made the default in Python 3.
