pYTHON with http ???????

I dont know anything about python ,so i begin to read manuals etc from various locations.
But i have a basic question here, please if someone know help

Thanks .

Look at this :

<a href=\"file://", lease, "\">
The "lease" is just a variable that receive a IP address that my python read from a file.
But when i see in the page appear with a space like this
file:// ipaddress
-------|---------
This space can't exist !!!!

How can I avoid this little space problem ? It's just a simple program to read my dhcpd.leases and take the IP'S and Name's of people connected then show into a page.
When the person click on the IP then the browser open the shared resources .
Vary simple, but i don't know how avoid this

Thanks alot !!!

Carlos.

Here is the complete file .
----------------------------------

#!/usr/bin/python
import string, os
from sys import stdout

#-------
#LeaseFile = "/etc/dhcpd.leases" # if you have Redhat before 6.1
LeaseFile = "/var/lib/dhcp/dhcpd.leases" # if you have Redhat 6.1 or later

#------- Markers
# Entries in the /etc/dhcpd.leases file start with the word 'lease',
# may span several lines, and then end with a '}'. Lines that start
# with a TAB (\t) descibe the lease, i.e. mac address, start, etc.
newleaseMarker = 'l' # lease starts with 'l'
endleaseMarker = '}' # ends with a '}'
infoMarker = '\t' # lease informational lines start with a TAB
startsMarker = '\ts' # \tstarts
endMarker = '\te' # \tend
abandonedMarker = '\ta' # \tabandoned
clientMarker = '\tc' # \tclient
uidMarker = '\tu' # \tuid
hardwareMarker = '\th' # \thardware

# ------- Date arrays (pretty print the date)
weekday = ["Sun", "Mon", "Tue", "Wed", "Thu", "Fri", "Sat"]
nthday = ["", "1st", "2nd", "3rd", "4th", "5th", "6th", "7th", "8th", "9th", "10th", "11th", "12th", "13th",

", "28th", "29th", "30th", "31st"]

#------- HTML Setup
print "Content-Type: text/html\n\n" # CGI header
print "<HTML><HEAD><LINK REL=\"stylesheet\" HREF=\"/lanlord/lanlord.css\">"

#------- Start the real work
indate = os.popen('date +"%A %B %m %r %Y"', 'r') # Get todays date

for line in input.readlines():

L[ipLeased] = {`ipLeased` : `entry`}

else:
ipLeased = line[6:len(line) -3]
clientLeased = 'None'
macLeased = 'None'

print "<h5>", len(L), " leases</h5><Table border=\"1\"><th>IP Address</th><th>Hostname</th><th>Lease Start</t
h><th>Lease End</th><th>MAC Address</th>"
dhcpLease = L.keys()
dhcpLease.sort()
for lease in dhcpLease:
infoLease = L[lease]
dataLease = infoLease.values()
infoLease = dataLease
lLease = string.splitfields(`infoLease`,"*")
lMac = lLease[0][3:21]
lDate = lLease[7][0:8]
print "<TR><td>", lease, "</td><td>", lLease[1],"</td><td>", lLease[2], lLease[4], lLease[3], "</td><
td>", lLease[5], lDate, lLease[6], "</td><td>",lMac,"</td></tr>\n"

print "</table><p><a href=\"file://", ipLeased, "\">Test Part</a></p></body></html>"

- End file

Just rename it into the cgi-bin with name test.cgi to see it working.
Can someone help here !!!
Thanks again .

Hi carnt, the problem is that when you join a string with a , then the space btween that and the variable counts i.e.

print "hey", variable, "."

if you replace the , with a + then the spacd shouldnt be a problem.

Hope this is what you were looking for.

Take care,
Mark.
