High-level Python SNMP library
https://github.com/trehn/hnmp

HNMP is a high-level Python library to ease the pain of retrieving and
processing data from SNMP-capable devices such as network switches, routers,
and printers. It's not meant to provide everything SNMP has to offer, but to
get rid of most of the suck inherent to writing Munin or Icinga plugins that
process SNMP data.

It is based on pysnmp.
