Lab 1 — Handle a Missing File Gracefully

Objective: Use try/except to catch a FileNotFoundError and print a helpful message.

Instructions

Create a file called lab1.py. Write a script that tries to open a file called missing_devices.txt. Since this file does not exist, the open will fail — catch the exception and print a helpful error message instead of crashing.

Your output must match exactly:

Error: device list file not found
Please provide a valid file path

Run it with python3 lab1.py. Paste your output below and submit.

Starter Code

try:
    with open("missing_devices.txt") as f:
        content = f.read()
        print(content)
except FileNotFoundError:
    print("Error: device list file not found")
    print("Please provide a valid file path")

💡 Show Hint

The file missing_devices.txt does not exist — that is the point. Python raises FileNotFoundError when open() cannot find the file. Catch it in the except block.
