Slide 7 (control flow):
- The bit about "pass when waiting for an external event or to do
nothing" is confusing IMHO; just say it's a no-op, needed
because the syntax forbids suites (intented blocks) to be empty.
- Perhaps mention ``else: ...`` on ``for`` and ``while`` loops.
Rare but very clean and handy when you need it.
Slide 13 (modules):
- You show how to use them but not how to create them. Say it
just executes a file and captures its namespace.
Slide 14 (dir):
- If you mention `__doc__`, show how to create one (who will
remember from slide 8?). Say it also works with modules &
classes.
- Definitely mention `help()`!
Last slides (classes):
These leave the impression they were cut off. If you have the
time:
- I suggest showing off some magic attrs, e.g. `__add__`,
`__str__` and perhaps `__getattr__`. `__iter__` is very cool
but not worth showing unless you also have the time for
generators...
- Say some words about Python's culture of type checking by
implemented interfaces rather than acutal type.
Last, 1 - 2 slides with overview of the standard library could be
nice. You can steal from the quickref_ ;-).
Of course not all these things require presence in the slides, some
can be just said out-of-band (and some are just bad ideas, make your
judgement)...
