How to Extract Query Parameter Values from a URL in Python?

Retrieving Parameters from a URL

To extract the value of a query parameter from a URL in Python, you can utilize the urllib.parse module. This process involves parsing the URL to access its query component and then utilizing the parse_qs function to extract the parameter values.

For example, consider the following URL:

https://www.example.com/some_path?some_key=some_value

To retrieve the value of the some_key parameter using Python 3:

<code class="python">from urllib.parse import urlparse
from urllib.parse import parse_qs

url = 'https://www.example.com/some_path?some_key=some_value'
parsed_url = urlparse(url)
parameter_value = parse_qs(parsed_url.query)['some_key'][0]

print(parameter_value)  # Output: "some_value"</code>

The parse_qs function returns a list. The [0] index retrieves the first item in the list, providing the parameter value.
