Lab 2 — Create Your Own device

Objective: Write a Python module with two reusable functions for processing device data.

Instructions

Create a file called device_utils.py with two functions:

format_hostname(name) — strips whitespace and lowercases the name
get_device_type(hostname) — returns "switch" if the name starts with sw, "router" if it starts with rtr, "firewall" if it starts with fw, otherwise "unknown"

Then create a file called lab2.py that imports device_utils and runs these calls:

import device_utils

print(device_utils.format_hostname("  SW-CORE-01  "))
print(device_utils.get_device_type("rtr-edge-01"))
print(device_utils.get_device_type("sw-access-01"))

Run python3 lab2.py. Paste your output below and submit.

Starter Code

# device_utils.py — paste this into device_utils.py (not lab2.py)

def format_hostname(name):
    return name.strip().lower()

def get_device_type(hostname):
    if hostname.startswith("sw"):
        return "switch"
    elif hostname.startswith("rtr"):
        return "router"
    elif hostname.startswith("fw"):
        return "firewall"
    else:
        return "unknown"

💡 Show Hint

Create two separate files: device_utils.py (the module) and lab2.py (the script that imports it). Both must be in the same directory.
