What are the best practices for URL decoding in programming?

When decoding URLs, it's important to use built-in libraries to handle special characters correctly. Always validate the input to avoid security issues.

Can you give an example of how to decode a URL in Python?

Sure! In Python, you can use the urllib.parse module. Here's a simple example:

import urllib.parse
url = 'https%3A%2F%2Fexample.com%2Fpath%3Fquery%3Dvalue'
decoded_url = urllib.parse.unquote(url)
print(decoded_url)

What should I be cautious about when decoding URLs?

Be cautious of malformed URLs and ensure you handle exceptions. Also, avoid exposing sensitive data through URLs.

Are there any performance considerations when decoding URLs?

Yes, decoding large URLs can be resource-intensive. It's best to decode only when necessary and to cache results if possible.
