Simple pysnmp example?

[Calab]

I'm running python 3.13. I have v 7.1.17 of the pysnmp module installed.

I'm trying to do a simple SNMP get, but I am having trouble understanding how pysnmp works. The examples I find online are out of date, don't work, or are confusing for me.

This is my code:

from pysnmp.hlapi.v3arch import *

community_string = 'mystring'
host = 'my_host'

x = get_cmd(SnmpEngine(),
           CommunityData(community_string),
           UdpTransportTarget.create((host, 161)),
           ContextData(),
           ObjectType(ObjectIdentity('1.3.6.1.2.1.1.5.0')),   # SysName
           lookupMib=False,
           lexicographicMode=False,
           )
           
print(next(x))

When run, I get the following error when I try to print(next(x)):
TypeError: 'coroutine' object is not an iterator

Can someone explain why this is, or better yet, provide a very simple SNMP get example using pysnmp?
