you might want to try embedding the page itself in the code (ugly, but if you're just starting out with python maybe the way to go).

this part is unnecessary, you already have the two \n's from the statement above it.

hmmm ... ok well here's how I would do something similar, we dont want to just guess if a file is there, we want it to be there and error else (or so I think, it is a counting script, and a couting script without a file cant really work ;-)

Now while Im sure this isnt the best way to do it (tho I dont think its all that bad either ;-) ....

#!/usr/bin/env python

import string

print 'Content-Type: text/html\n\n'
print '<html><body>'

count = '0'

try:
	count = open('count.txt').read()
	count = string.strip(count)
	num = string.atoi(count)
	print "You are the "+str(num+1)+"th visitor to this page"
except IOError:
	print "No valid file"
except ValueError:
	print "No valid count value"

print '</body></html>'
