Network automation,
done properly
I'm a network engineer passionate about automation. Python and Ansible instead of repeating the same CLI commands by hand. Here's what I'm learning, in detail.

// In Practice
A real script, not a toy example — connect to a device, pull output, done.
scan_network.py
#!/usr/bin/env python3
import os
from netmiko import ConnectHandler
device = {
"device_type": "cisco_ios",
"host": "10.0.0.1",
"username": os.environ["NET_USER"],
"password": os.environ["NET_PASS"],
}
with ConnectHandler(**device) as conn:
output = conn.send_command("show ip int brief")
print(output)
