Yep, and I have to stop trying to post on too little sleep.
Ok, how about... ?
def count_records(record_obj, start=0, end='to-end'):
if end == 'to-end':
end = len(record_obj)
n = 0
for rec in record_obj.data[start:end]:
if not rec.isblank():
n += 1
return n
This isn't really different from using None. While it's possible to
avoid None, its probably not worth the trouble. I use it myself.
Here's something interesting:
import time
x = None
t = time.time()
for i in range(1000000):
if x==None:
pass
print 'None:',time.time()-t
x = 'to-end'
t = time.time()
for i in range(1000000):
if x=='to-end':
pass
print 'String:',time.time()-t
>>>
None: 0.46799993515
String: 0.360000133514
Of course the difference this would make on a single call in practically
Nill.
Anyway, time to call it a night so tomorrow I don't make anymore silly
mistakes on comp.lang.python. :)
Cheers,
Ron
