Crate Loop into os file

[paulo79]

Hi all, I have this shell script that goes to a loop on file lines:

for dDames in `cat /tmp/Dnames`
do
#echo $dgname
    for FNames in `cat /tmp/FNames`
    do
       echo $DNames
       echo $FNames
done
done

How do I do same loop in python ?

File contets are like :

cat /tmp/Fnames
CELADM16
CELADM17
CELADM18

cat /tmp/Dnames
RECOC1
DBFSC1
DATAC1
