Snimpy is aimed at being the more Pythonic possible. You should forget that you are doing SNMP requests. Snimpy will rely on MIB to hide SNMP details. Here are some "features":

MIB parser based on libsmi (through CFFI)
SNMP requests are handled by PySNMP (SNMPv1, SNMPv2 and SNMPv3 support)
scalars are just attributes of your session object
columns are like a Python dictionary and made available as an attribute
getting an attribute is like issuing a GET method
setting an attribute is like issuing a SET method
iterating over a table is like using GETNEXT
when something goes wrong, you get an exception
