Which Python HTTP Request Library is Best: urllib, urllib2, urllib3, or Requests?

Comparison of HTTP Request Modules in Python: urllib, urllib2, urllib3, and Requests

In Python, there are several modules available for making HTTP requests: urllib, urllib2, urllib3, and requests. While they all serve the purpose of interacting with web servers, they differ in their features, ease of use, and performance.

urllib and urllib2

urllib and urllib2 are the oldest HTTP request modules in Python. urllib provides a low-level interface for building requests, while urllib2 adds support for higher-level concepts such as cookies and authentication. However, both urllib and urllib2 can be cumbersome to use due to their complex syntax and lack of friendly APIs.

urllib3

urllib3 is a more modern and efficient HTTP request library that aims to simplify the development of HTTP clients. It provides a higher-level API than urllib and urllib2, making it easier to make requests and handle responses. Urllib3 also offers support for advanced features such as connection pooling, timeout handling, and automatic decompression.

Requests

Requests is the most popular and recommended HTTP request library in Python. It offers a simple and intuitive API that is both powerful and user-friendly. Requests abstracts away the complexity of sending and receiving HTTP requests, allowing developers to focus on their business logic rather than dealing with the intricacies of the HTTP protocol.

With its extensive feature set, ease of use, and excellent performance, requests has become the go-to HTTP request library for Python developers. It supports a wide range of HTTP methods, includes JSON decoding functionality out-of-the-box, and provides built-in support for many useful features such as session management, SSL verification, and automatic header parsing.

In addition to the features mentioned above, requests offers:

• Unicode support for response bodies
• Multipart/form-data encoding support
• Cookie jar persistence
• Proxy support

While urllib, urllib2, and urllib3 can still be used for HTTP requests, requests is generally considered the preferred option due to its superior usability, features, and performance. It is well-maintained and widely adopted by the Python community, making it a reliable and widely supported choice for HTTP request development.
