No - the function snmpwalk returns a set of 4-tuples:
var.tag (the object OID)
var.iid (the index)
var.val (the value)
var.type (the type)
Have a look at 'python/netsnmp/tests/test.py' for examples.

Try the following:
import netsnmp
vars = netsnmp.VarList( netsnmp.Varbind('ifDescr'))
res = netsnmp.snmpwalk( vars, Version = 1, DestHost =
'localhost', Community = 'public' )
for var in vars:
print "ifIndex value = ", var.iid, "\tifDescr value =", var.val

It's not the bindings' problem.
