Why would anyone build with this?

REASON 1

Call a REST API from a Python script and parse the JSON response with minimal code.

REASON 2

Log in to a website and maintain the session across multiple requests to scrape authenticated pages.

REASON 3

Download a large file from a URL without loading the entire file into memory at once.

REASON 4

Automate form submissions or web interactions from a Python script.

Wtf does this do

Requests is a Python library for making HTTP requests, which are the messages your code sends when it needs to talk to a web server, fetch a web page, call an API, or submit data to a remote service. Python has a built-in module for this called urllib, but it is notoriously verbose and awkward to use. Requests was created to make the same tasks simple and readable, following the philosophy that the code should express intent clearly without boilerplate. With Requests, fetching a web page or calling an API takes just one line. It automatically handles things that would otherwise require manual work: adding query parameters to URLs, encoding POST data, managing cookies across multiple requests in a session, verifying SSL certificates, handling redirects, and decompressing compressed responses. It also makes it easy to set timeouts so your program does not hang waiting forever, upload files in multipart format, stream large downloads without loading everything into memory at once, and use authentication schemes like basic auth or digest auth. You would use Requests any time your Python program needs to communicate with a web service, whether that is calling a REST API, scraping web pages, downloading files, or automating web interactions. It is one of the most downloaded packages in the entire Python ecosystem, used in millions of projects as the standard way to do HTTP in Python. The library requires Python 3.10 or newer and is installed via pip. The tech stack is pure Python with no compiled dependencies for the core functionality, though optional packages can add SOCKS proxy support.

Yoink these prompts

Prompt 1
Using the Python requests library, write a script that calls a JSON REST API with an API key in the Authorization header, handles 4xx and 5xx errors gracefully, and pretty-prints the response.
Prompt 2
Show me how to use requests.Session() to log in to a website with a POST request and then fetch pages that require being logged in.
Prompt 3
Write Python code using requests to download a large file in streaming chunks and save it to disk, showing download progress.
Prompt 4
How do I use requests to upload a file in multipart form format and include additional form fields in the same POST request?
Prompt 5
Demonstrate using requests with automatic retry logic and exponential backoff when an API returns 429 rate limit errors.
