Is Urllib built in Python?

Feb 20, 2024 ยท 2 min read

Python provides the urllib module for making HTTP requests in your code. urllib is part of Python's standard library, meaning it is built-in and ready to use without needing to install any additional packages.

Is urllib Built Into Python?

Yes, urllib is built into Python - no installation required. To use it, simply import urllib or parts of it like:

import urllib.request

Then you can start making HTTP requests as shown in the examples below.

urllib Usage Example

Here is a simple example to make a GET request and print the response:

import urllib.request

response = urllib.request.urlopen('https://www.example.com')
print(response.read())

This opens the website, gets the response, and prints the HTML of the page.

Tips for urllib

When using urllib, keep these tips in mind:

  • For GET requests, pass URL parameters as a string concatenated to the URL
  • For POST requests, encode parameters and data to send using urllib.parse.urlencode
  • Add headers to requests using an urllib.request.Request object
  • Always handle errors - use try/except blocks and check status codes
  • Alternatives to urllib

    While quite useful, urllib has been superseded by some 3rd party modules like requests for making HTTP calls. requests provides a simpler API and more features like connection pooling.

    So if you find urllib limiting, consider alternatives like requests. But urllib is perfectly fine for basic HTTP needs, and being built-in means one less dependency.

    Next Steps

    To recap, Python's urllib module provides the building blocks for fetching data and interacting with APIs over HTTP. Give it a try on your next project! Check the official documentation for more usage examples and details on all available functions.
