Help processing GPS data from a server

I have having issues with processing data after it closing the connection for a database. nprompt is a list that takes string names
from two users. The print of the list shows the exact copy of the x y coordinates. Not sure whats wrong with my code.


for k in nprompt:
if k == "t4":
#Function to process lat and lon
newLat = []
newLon = []
for x in lat:
if x != 0:
newLat.append(x/1000000)
else:
newLat.append(x)

for x in lon:
if x != 0:
newLon.append(x/1000000)
else:
newLon.append(x)

for k in nprompt:
if k =="taylor":
#Function to process lat and lon
newLat2 = []
newLon2 = []
for x in lat:
if x != 0:
newLat2.append(x/1000000)
else:
newLat2.append(x)

for x in lon:
if x != 0:
newLon2.append(x/1000000)
else:
newLon2.append(x)


print newLat [5:40]
print newLat2 [:40]
