Python Name Error
Hi There,

I have the following code:

Code:
import time
import paramiko


node_list = ['oj_msp_ts1', 'oj_msp_ts2', 'oj_msp_ts3', 'oj_msp_ts4', 'oj_msp_ts5', 'oj_msp_ts6', 'oj_msp_ts7', 'oj_msp_ts8', 'oj_msp_ts9', 'oj_msp_ts10', 'oj_msp_ts11', 'oj_msp_ts12', 'oj_msp_ts13']
for node in node_list:
    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.connect(node, username='lord', password='xxxx')
    variables = {}
    stdin, stdout, stderr = ssh.exec_command("snmpwalk -v1 localhost -c public .1.3.6.1.4.1.193.126.3.6.1.1.1.1.7.5 | awk '{print $NF}'")
    variables[node + "_pull_first"] = stdout.read().strip()
    print str(oj_msp_ts1_pull_first)
    ssh.close()

But for some reason which I have been thinking about for 2 days now, it keeps giving the following error:

NameError: name 'oj_msp_ts1_pull_first' is not defined

This is quite funny to figure out and am somehow surprised that am having issue with (it should be easy to figure out, it's just a couple of lines).

Any input will be appreciated.

If you showed me where it is defined, I'd share your surprise.

Hi RudiC,

This is where it is defined via the dict:

Code:
variables[node + "_pull_first"] = stdout.read().strip()

node is been picked up by the FOR loop (node_list).

I hope it is clear

So the name isn't blahblah_pull_first, it's variables['blahblah_pullfirst']

Change it to that.... you'll probably want an intervening var with the dynamic name:

dynname = node + "_pull_first"

so you can use that name in both places (variables[dynname])
