from easysnmp import Session
host = '10.124.xxx.xx'
session = Session(hostname=host, community='xxxwifi', version=2)

# Perform an SNMP walk
system_items = session.walk('1.3.6.1.4.1.25053.1.3.2.1.1.2.2.1.1')

# Each returned item can be used normally as its related type (str or int)
# but also has several extended attributes with SNMP-specific information
for item in system_items:
    print '{oid}.{oid_index} {snmp_type} = {value}'.format(
        oid=item.oid,
        oid_index=item.oid_index,
        snmp_type=item.snmp_type,
        value=item.value
    )
