Perhaps even nicer:
[key for key, evtime in eventData.iteritems() if evtime < time.time()]
This way the dictionary iterates over key, value tuples.

I'm a little fuzzy on the details of that, I will have to look over some

Just because it would dump a bunch of stuff to the screen really quickly
that you couldn't read as soon as some events expired.

Mmm, to nit-pick a little, dictionaries are iterables, not iterators.
They don't have a next() method.

I may sound like a know-it-all, but dictionaries *are* iterators.
[a for a in eventData if eventData[a] < time.time()]
This is more efficient. The keys method creates a list in memory first and
then it iterates over it.
Unnecessary.

This is almost never what you want to do, for pre
I'm sure this is a classic beginner's topic, and I've read a bit about it
online already, but I'd like to ask about it here as well. I want to assign
names to objects based on what a user inputs so that I can later keep track of
them.
In particular, I want to time multiple events by gett
