URL Redirect Checker

• This script checks a list of URLs and returns their redirect location and status code.
• The check_redirects function takes base_url and paths as arguments.
• The script combines the base URL with each relative path using urljoin.
• The script sends a GET request to each combined URL and prints the HTTP status code and final URL after any redirects, or indicates if there were no redirects.
• The main block checks for enough command-line arguments and calls check_redirects with the base URL and relative paths.

Requirements

• Python 3 minimum
• requests library - this script will detact if this isn't installed and prompt the user to install it.

Usage

python <path to file>/check_redirects.py <base_url> <path1> <path2> ...

For a base URL of 'https://www.example.com' and the paths '/women/shoes' and '/men/shirts':
