Well, os.listdir doesn't include "." or ".." anyway as you can see here
<http://docs.python.org/library/os.html#os.listdir>
So, just a simple len(os.listdir(my_directory)) will suffice..
A couple more points:
-It's better looking and more readable (to me that means Pythonic) to
store that ugly path to a variable first.
-Whenever you see yourself repeating a chunk of code, make a function
out of it!
So, your program now is
------------------------------
import os, time
my_directory =
'/Volumes/sgtb/lac/comps/Z353_002/renders/Z353_002_comp/Z353_002_comp_v04/2048x1556'
while len(os.listdir(my_directory)) <= 8:
print 'waiting'
time.sleep(5)
print 'still waiting'
time.sleep(5)
print 'eight'
-------------------------------

I got it working but it seems little clunky. If I have a folder with 6
files in it, python will print out "waiting, still waiting, waiting,
still waiting..." if I add 3 new file to the folder python prints
"eight". This is the basic behaviour I want but is there a more
pythonic way to write this.
import os, time
theFilesAsList = []
for anItem in
os.listdir('/Volumes/sgtb/lac/comps/Z353_002/renders/Z353_002_comp/Z353_002_comp_v04/2048x1556'):
if anItem[0] != ".":
theFilesAsList.append(anItem)
theNumberOfImages = len(theFilesAsList)
while theNumberOfImages <= 8:
print 'waiting'
time.sleep(5)
print 'still waiting'
time.sleep(5)
theFilesAsList = []
for anItem in
os.listdir('/Volumes/sgtb/lac/comps/Z353_002/renders/Z353_002_comp/Z353_002_comp_v04/2048x1556'):
if anItem[0] != ".":
theFilesAsList.append(anItem)
theNumberOfImages = len(theFilesAsList)
print 'eight'
