checked it with timeit, runs faster then first implementation 4 times :)
input:
print timeit.timeit("checkio(random.sample(xrange(10000), 1000))", number=1000, setup="from __main__ import checkio; import random"), \
timeit.timeit("checkio2(random.sample(xrange(10000), 1000))", number=1000, s

It won't work if you change some of the attributes. I'm talking about self.east and self.north

It's not pythonic. Better not use counters and this kind of stuff u use in c/c++ or java.

instead of:
while t.replace(' ', ' ') != t:
t = t.replace(' ', ' ')
you could use:
re.sub(' +', ' ', text)

if len(args)==0: and if args: is the same, because in python all empty list, dicts etc. means False.

Better use slicing for it. Like this: array[::2]. First two parameters are for begin and end indexes. If you want whole list, you don't touch it (for example [1,2,3][:] will retrieve the same list). Third parameter is for "step". For array=[0,1,2,3,4,5] it will retrieve [0,2,4].

Better use generator instead of creating a list for loops. Because u iterating two times, first when you create list, then inside of loop. It is slower 2 times. Just change [] to () and you will not create a list, just iterate over it.
