std_print() shows the output with an error message

[HaiderNL]

Hi, The std_print() does give an output but not properly. It says agg_result is not defined. But it is already defined. Any idea what's wrong with the code ?

from nornir import InitNornir
from nornir_netmiko import netmiko_send_command
nr = InitNornir()

with open("commands.txt") as f1:
    f1 =f1.read().splitlines()

def fn1(x):
    for c in f1:
        x.run(
            task = netmiko_send_command,
            command_string = c
        )
    return agg_result

agg_result = nr.run(task=fn1) 

def std_print(agg_result):
    print()
    for k, multi_result in agg_result.items():
        print('-' * 50)
        print(k)
        for result_obj in multi_result:
            if isinstance(result_obj.result, str):
                print(result_obj.result)
            else:
                pprint(result_obj.result)
        print('-' * 50)
        print()
    print()

std_print(agg_result)

Your function here:

def fn1(x):
    for c in f1:
        x.run(
            task = netmiko_send_command,
            command_string = c
        )
    return agg_result

Is trying to return a variable named agg_result, but that variable doesn't exist (i.e. you haven't defined it anywhere).,

Oh, I thought "agg_result = nr.run(task=fn1) " would be sufficient. Well then, I'm going to play around with till it's fixed.
