You've got lots of problems here:
  - you switch the case of nPos in the for loop
  - you never print out the cookie, so it never gets sent to the client

Try something like this (untested):

import os
import Cookie

# Create a cookie
#    If the env. var. HTTP_COOKIE does not exist, then
#    we create an empty cookie.
kaka = Cookie.SmartCookie( os.environ.get("HTTP_COOKIE", "") )

# Set nPos to the cookie's value, if it exists
# If the cookie doesn't include nPos, then default to a value of 0.
try:
    nPos = kaka["nPos"].value
except:
    nPos = 0

# I do not know why anyone would do this, but..
for i in range(20):
    nPos = nPos + 1

# Set the cookie's new value
kaka["nPos"] = nPos

# Send a response to the client
#   Include the cookie in the headers
#   Put the value of nPos on the page

print "Content-type: text/html"
print kaka
print

print "<HTML><BODY>%d</BODY></HTML>" % nPos
