Tell me something about /.

Sure! Here's a quick and easy way to tell if you have / in front of you:

1. Find any slashes (/) that are not followed by another character.
2. If there are no more slashes, you have the beginning of an URL.
3. If you see a URL with a single slash, but don't find any slashes after it, you've probably got an HTML document instead of a URL.
4. To get rid of any remaining slashes at the end of your string, simply remove them using the replace() function in JavaScript or Python (and Python has a built-in way to remove a single character using the rstrip() method):

import re
url = 'http://www.example.com/'
new_url = url.replace('/', '')
print(new_url)  # Output: http://www.example.com

I hope that helps you get started! Let me know if you have any other questions.
