Thank you for your reply. I understand that it is odd, but my program is being
called from a hubot and returning data to it as well. I have figured out how to
make the changes to get it to output the correct data in the correct format,
but now I am getting a "Premature end of script headers" error. I have the
correct #! line and the output from the command line shows no errors that would
be interfering. Is there a way to make sure it is showing me all the errors? To
increase error logging?
------
!/usr/bin/env python
import cloudfiles
import random
import sys
import array
conn = cloudfiles.get_connection('username', 'key')
containers = conn.get_all_containers()
i=0
print "Content-type: text/html";
wholelist=containers[0].list_objects()
random.shuffle(wholelist)
newlist=[]
#newlist=wholelist[:]
try:
# print sys.argv[1]
if "=" in sys.argv[1]: sys.argv[1] = sys.argv[1].rstrip("=")
# print sys.argv[1]
del wholelist[int(sys.argv[1]):]
while i < int(sys.argv[1]):
newlist.append("http://example.com/"+wholelist[i].rstrip())
i = i+1
except IndexError, e:
del newlist[5]
except Exception, err:
print 'Caught an exception'
print newlist,
