I used this on CentOS 5 without any problems :
  clearpart --all --initlabel

I also use an pre script to detect the number of drives on the server

%pre
# Determine how many drives we have
set $(list-harddrives)
let numd=$#/2
d1=$1 # This is the device of disk 1
d2=$3 # This is the device of disk 2, etc.
S1=$2 # This is the size of disk 1
S2=$4 # This is the size of disk 2, etc.

# This would be a partition scheme for two or more drives
if [ $numd -ge 2 ]; then cat << EOF >> /tmp/partinfo
# Partition clearing information
clearpart --drives=$d1,$d2 --all --initlabel
part / --asprimary --fstype="ext3" --ondisk=$d1 --size=1024
part /boot --asprimary --fstype="ext3" --ondisk=$d1 --size=200
part swap --fstype="swap" --ondisk=$d1 --recommended
part /var --fstype="ext3" --ondisk=$d1  --grow --size=1
part /var/spool/squid --fstype="ext3" --ondisk=$d2  --grow --size=1
part /usr --fstype="ext3"  --ondisk=$d1 --size=4096
part /tmp --fstype="ext3"  --ondisk=$d1 --size=1024
part /home --fstype="ext3"  --ondisk=$d1 --size=5120
EOF

else

cat << EOF >> /tmp/partinfo
# Partition clearing information
clearpart --drives=$d1 --all --initlabel
part / --asprimary --fstype="ext3" --ondisk=$d1 --size=1024
part /boot --asprimary --fstype="ext3" --ondisk=$d1 --size=200
part swap --fstype="swap" --ondisk=$d1 --recommended
part /var --fstype="ext3" --ondisk=$d1  --size=4096
part /var/spool/squid --fstype="ext3" --ondisk=$d1  --grow --size=1
part /usr --fstype="ext3"  --ondisk=$d1 --size=4096
part /tmp --fstype="ext3"  --ondisk=$d1 --size=1024
part /home --fstype="ext3"  --ondisk=$d1 --size=5120

In Python,Perl or Shell? I'm searching how to wipe all drives with 
parted or fdisk.

Here is my kickstart :
