find a task you need a solution too.
are there any regular admin task you perform that could be automated?
do you have any hobbies that could benefit from computerisation?

genuine tasks are always better that those created purely to teach

I agree, but also, pick something that's small and self-contained. Try
to find a project that you can complete (to the point of usability)
within a day, or at most a week, preferably within the space of a page
or two of code. As an added advantage, you'll be able to ask for code
review, here or somewhere else; you can learn a lot by writing your
code first, and then having other programmers offer comments. (Note
that I didn't say "better programmers" or even "more senior
programmers". It's called "peer review" in some circles, because the
point is that anyone can learn from anyone else.)

I googled for:

     "Scott Bradner" "IETF motto"

It gave me:

     The IETF motto is "rough consensus and running code."

Presumably "rough consensus". As long as most people agree (as opposed
to total consensus, where *everyone* agrees), and as long as the code
can be made to run, perfection is a luxury hat the IETF doesn't strive
for. It's a form of "practicality beats purity" as it applies to
standards development.

The joke may be that this is only approximately correct spelling, as
well as only approximate consensus and approximately working code. Or
that might just be a transcription error.

I was wondering about that after I posted.  I did find that
misspelling in one or two e-mails in a mailing list archive, but it
didn't really seem like it was being used as an in-joke.

In [1]: help(sum)
Help on built-in function sum in module builtins:

sum(...)
     sum(iterable[, start]) -> value

     Return the sum of an iterable of numbers (NOT strings) plus the value
     of parameter 'start' (which defaults to 0).  When the iterable is
     empty, return start.

BTW I have the answer to question 2, but there is no way I would run
the code on numbers much more than 100000 and it wants the answer for
4,000,000.

So that's teaching you that there must be a more elegant approach than 
brute-force.  Sometimes you can use cleverer programming, sometimes you 
need cleverer math.  Sometimes both.

As a trivial example, suppose you're asked to sum the numbers from 1000 
to 10**25

Brute force would take a few millenia, as something like
     ans = sum(range( BIG ) - sum(range(1000))

But just knowing the math lets you simplify it to something like
    ans = (1000 + BIG) * (BIG - 1000) / 2

(give or take a few plus/minus ones)

Suggestion: Master the brute-force approach first, and use that (on
small ranges) to verify the simplified version. And if you already
happen to know the sum of all numbers from 1 to 100, say, then you can
test both approaches against that, to be sure they're right.

Ooh. I had to jump onboard to defend this. Project Euler is an absolute delight to do with Python :)
You should totally give it a whirl.
