[Crossposted to tutor and general mailing list]
Hi,
I'd like to extend the dictionary class by creating a class that acts
like a dictionary if the class is instantiated with a dictionary and
acts like a "dictitem" ([(key1, value1), (key2, value2), ...]) if
instantiated with a list (that is dic

Further thoughts come to mind, after looking more closely at your code.

From the Python 3.5.2 docs:
6.15. Evaluation order
Python evaluates expressions from left to right. Notice that while
evaluating an assignment, the right-hand side is evaluated before the
left-hand side.
Thus, spam = eggs = cheese = obj is equivalent to:
spam = (eggs = (cheese = obj))

He is definitely not active on this list. The most recent message from
him here (not cross-posted) seems to be in September 2014.
Maybe there's something

These "accessible" objects become read-only even if it's mutable. For immutable
objects, you can't even create a new one in the deen's namespace.

The render_template function looks for a directory called "templates"
and a file in that of the given name. So you'll need to have
"templates/index.html"
I have a script that can be broken up into four subtasks. If any of those
subtasks fail, I wish to exit with a different exit code and error.
