pysnmp returns a sequence of two-component tuples. These components are OID and value. That is called variable-binding in SNMP.
So what you see might be:
varBinds = [ (ObjectIdentifier('1.3.6.1.1.18443.1.1'), Integer(9016)) ]
which is a list of variable-bindings.
To save just the value part of the first variable binding in a sequence you could need to:
varBind = varBinds[0]
oid, value = varBind
str(value)
or
int(value)
depending on the database data type.
