pip install httpxHTTPX is a fully featured HTTP client library for Python 3. It includes an integrated command line client, has support for both HTTP/1.1 and HTTP/2, and provides both sync and async APIs.
Install HTTPX using pip:
$ pip install httpx
Now, let's get started:
>>> import httpx
>>> r = httpx.get('https://www.example.org/')
>>> r
<Response [200 OK]>
>>> r.status_code
200
>>> r.headers['content-type']
'text/html; charset=UTF-8'
>>> r.text
'<!doctype html>\n<html>\n<head>\n<title>Example Domain</title>...'
Or, using the command-line client.
$ pip install 'httpx[cli]' # The command line client is an optional dependency.
Which now allows us to use HTTPX directly from the command-line...

Dependencies
The HTTPX project relies on these excellent libraries:
httpcore- The underlying transport implementation forhttpx.h11- HTTP/1.1 support.
certifi- SSL certificates.idna- Internationalized domain name support.sniffio- Async library autodetection.
As well as these optional installs:
h2- HTTP/2 support. (Optional, withhttpx[http2])socksio- SOCKS proxy support. (Optional, withhttpx[socks])rich- Rich terminal support. (Optional, withhttpx[cli])click- Command line client support. (Optional, withhttpx[cli])brotliorbrotlicffi- Decoding for "brotli" compressed responses. (Optional, withhttpx[brotli])zstandard- Decoding for "zstd" compressed responses. (Optional, withhttpx[zstd])
A huge amount of credit is due to requests for the API layout that
much of this work follows, as well as to urllib3 for plenty of design
inspiration around the lower-level networking details.
