Subject: [Python Wpg] Last meeting, next meeting, and March tutorial idea
Message-ID: <17858.46733.502537.595690@gavel.swilliams.ca>
Despite the website wiki at http://winnipug.ca not always being
up-to-date, we are meeting regularly. In January I presented some
ugly and beautiful code as discussed. I'll post some next.
In February Scott is planning to present, as discussed in November, on
development with Glade, right Scott? Feel free to give me a better
title, or correct me, or edit the wiki yourself.
We had some discussion about making the March meeting a 2-hour Python
primer or Introduction to Python session targeted at folks who are new
or potential future Python programmers. Someone mentioned that April
might be too late in the year for this to work well.
With respect to who would do the tutorial, I'm willing to organize it
but would like some others to help.
We talked about the possibility of Syd having his Django (right?)
presentation, originally scheduled for March but moved to April, ready
hiding up his sleeve at the March tutorial meeting in case the turnout
for the tutorial is low.
Are there other relevant discussion points I've forgotten?
Does March sound good for a tutorial? How much interest would there
be from folks on this list or others they might invite? Are some of
you willing to do some publicity?
Stuart.

Subject: [Python Wpg] Some beautiful code
Message-ID: <17858.46850.857344.140939@gavel.swilliams.ca>
Here's a snippet of code we looked at at the last meeting. To
understand it by example see the tests at the bottom.
I made the comment at the meeting that when I rewrote it to be more
general it was much shorter and simpler.
def old_generate_matches(itera, iterb):
"""Take two iterables which return tuples (key, content).
Return pairs of items (as a tuple) that share the key
or an item paired with None if a matching element is missing."""
needed = object() # unique sentinel, so None is allowed in set
a, b = needed, needed
while True:
if a is needed:
try:
keya, a = itera.next()
# if a is None:
# raise ValueError('Iterable cannot contain None')
except StopIteration:
while True:
try:
keyb, b = iterb.next()
yield (None, b)
except StopIteration:
return
if b is needed:
try:
keyb, b = iterb.next()
# if b is None:
# raise ValueError('Iterable cannot contain None')
except StopIteration:
yield (a, None) # we aleady have an A from try above
while True:
try:
keya, a = itera.next()
yield (a, None)
except StopIteration:
return
if keya == keyb:
yield (a, b)
a, b = needed, needed
elif keya > keyb:
yield (None, b)
b = needed
else:
yield (a, None)
a = needed
def generate_matches(*iters):
"""Take N iterables which return tuples (key, content).
Return tuples of items that share the key, filling with
with None if a matching element is missing."""
nelements = len(iters)
needed = object() # a sentinel that's better than None
done = object()
alldone = [done] * nelements
keys = [needed] * nelements
elements = [None] * nelements
while True: # always at least one needed when we enter
for i in range(nelements):
if keys[i] is needed:
try:
keys[i], elements[i] = iters[i].next()
except StopIteration:
keys[i] = done
elements[i] = None
# we now have 3 values, maybe less, maybe all done
if keys == alldone:
break
minkey = min(keys)
results = [None] * nelements
for i in range(nelements):
if keys[i] == minkey:
results[i] = elements[i]
keys[i] = needed
yield results
def gen_gm(a, b):
return (iter([(int(e), int(e)) for e in a.split()]),
iter([(int(e), int(e)) for e in b.split()]))
def test_generate_matches():
assert (list(generate_matches(*gen_gm('1 2 3', '1 2 3')))
== [[1, 1], [2, 2], [3, 3]])
assert (list(generate_matches(*gen_gm('1 2', '1 2 3')))
== [[1, 1], [2, 2], [None, 3]])
assert (list(generate_matches(*gen_gm('1 2 3', '1 2')))
== [[1, 1], [2, 2], [3, None]])
assert (list(generate_matches(*gen_gm('1 2 4 7 8', '1 2 3 5 6 8')))
== [[1, 1], [2, 2], [None, 3], [4, None], [None, 5], [None, 6], [7, None], [8, 8]])

I',m a newbie and would definitely be very interested in this tutorial.
Thank you

Seconded. I'd definitely make a more significant effort to (finally) show up
if it was a tutorial topic. Unfortunately, four years of Computer Science
doesn't equate to "Python proficiency." :)

Message-ID: <45E301A2.7020801@gmail.com>
I managed a whole three weeks of personal uptime before catching this
one. It's not as bad as the last one, but it seems I have a constant
headache and coughing with this one. If it turns out to be a short term
one I'll make it to the meeting. Otherwise I won't.
Scott, I'll send you a separate e-mail.
Later
Mike
