Neither, or either. For timing small code snippets, the right tool is
the timeit module

Hi,
First-time poster here. I've a question about loop efficiency - I was
wondering whether this code:
i = 0
while i < 1000:
do something
i+=1
is more efficient than:
for i in range(1000):
do something
or:
for i in xrange(1000):
do something

Hi tutors!
I'm not a hard-core programmer but have used Python in systems
administration (it makes sense to me to use a scripting language which
supports both Windows and Unix).
The code below is an excerpt from a module I have written to collect
information about hosts on my network and populate

Hi Jeff how are you today?
Well about your question... I copy and pasted your code and it worked fine for
me. Well except for in the code bit you posted you forgot to give a guess a
value before it was referred to. So under number = 44 I just wrote guess = 0
and
it worked fine.
But perhaps
I'm trying to run the below program and get it to print out feedback as the

Alan,
Ah ha, ungetch(), that is what I was needing. I had be trying to simulate
kbhit() with getch() and keep being left with unhandled data in the buffer.
I had resorted to a trash=raw_input() to clear it.
Many thanks,

The counter is there so that it limits the iteration to only the first rows,
i actually left it there because i used it earlier to print out specific
rows.

Thanks Tim, that worked like magic.
I now have another challenge on the same file, in this case, i am trying to
extract just a column as PARTY, I successfully wrote the header but instead
of having each element in a single excel block like this:

ACD
ACN
ACPN

ADC
ALP
ANPP

Profiling is really intended to profile a complex set of operations
not a single statement, for that timeit() would be a better choice.
However in this case, it may be that the time is so low it simply
doesn't register. Have you already imported math for example?
In which case you are effective

Neither of those, either use timeit() or the Python profiler.
They are both specifically
