No.

pygrub:
- is a python script (which, IIRC, also installs several python modules)
- runs on dom0
- extract kernel and initrd from a domU image (file, partition, LVM,
etc) and put it on dom0 (/var/lib/xen/...)
- starts domU using the above kernel and initrd

You can test it yourself btw: Run "pygrub -i /path/to/wherever/your/domU/image"

pvgrub, on the other hand, runs completely on domU. So some might say
pvgrub is "safer" than pygrub.
