Well, this looks like it is going to do it:
[root at localhost tmp]# fdisk -l /dev/loop0

Disk /dev/loop0: 102 MB, 102400000 bytes
4 heads, 32 sectors/track, 1562 cylinders
Units = cylinders of 128 * 512 = 65536 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x0000804e

      Device Boot      Start         End      Blocks   Id  System
/dev/loop0p1               1        1563       99999+  83  Linux
[root at localhost tmp]#

Here is how I decide to get the number of sectors:
#!/usr/bin/python

import os
import sys
import parted


size = os.stat("/tmp/file").st_size
sectors = size / 512 - 1

device = parted.Device(path="/dev/loop0")
disk = parted.freshDisk(device, 'msdos')

start = 1
end = sectors

new_geom = parted.Geometry(device=device,
                           start=start,
                           end=end)



partition = parted.Partition(disk=disk,
                             type=82,
                             geometry=new_geom)


constraint = parted.Constraint(exactGeom=new_geom)




disk.addPartition(partition=partition,
                  constraint=constraint)


disk.commit()

I'll keep workking with this and update you with the latest, as soon
as I get more done.
