Lab 1 — Check If Files Exist Using the os Module

Objective: Import the os module and use os.path.exists() to check for specific files.

Instructions

First, create a directory and two files in your terminal:

mkdir lab6
touch lab6/network_devices.txt lab6/site_map.txt

Then create a file called lab1.py in your working directory and run it. It should check for three specific files inside lab6/ and print whether each one was found or not.

Your output must match this format exactly:

Found     : network_devices.txt
Found     : site_map.txt
Not found : lab_config.txt

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

Starter Code

import os

files = ["network_devices.txt", "site_map.txt", "lab_config.txt"]

for filename in files:
    path = os.path.join("lab6", filename)
    if os.path.exists(path):
        print(f"Found     : {filename}")
    else:
        print(f"Not found : {filename}")

💡 Show Hint

Use os.path.join("lab6", filename) to build the path. os.path.exists() returns True or False.
