In the Python Standard Library, at the end of :
 - Section "20.7.3. Examples" of "20.7. httplib — HTTP protocol client" (for Python 2.7.6) 
 - Section "20.10.3. Examples" of "20.10. http.client — HTTP protocol client" (for Python 3.2.5)
 - Section "21.12.3. Examples" of "21.12. http.client — HTTP protocol client" (for Python 3.3.5, Python 3.4.0, and Python 3.5a0)

the last example is described this way (change httplib for http.client for Python 3.2+):

--------

>>> # This creates an HTTP message
>>> # with the content of BODY as the enclosed representation
>>> # for the resource http://localhost:8080/foobar
...
>>> import httplib
>>> BODY = "***filecontents***"
>>> conn = httplib.HTTPConnection("localhost", 8080)
>>> conn.request("PUT", "/file", BODY)
>>> response = conn.getresponse()
>>> print response.status, response.reason
200, OK

--------

Is it possible that the request method should have been called this way:

conn.request("PUT", "/foobar", BODY)
                      ^^^^^^
Thank you

A simple docs patch would definitely help here. Thanks for the bug report.

Do you have some documentation on how to do a "docs patch" ?

I'm sorry this is the first time I'm reporting a bug.

You should have a look at the following guides:

https://docs.python.org/devguide/docquality.html
https://docs.python.org/devguide/patch.html

Sure, here is the information on how to create a patch - https://docs.python.org/devguide/

It could feel that there are multiple steps, but the process is easy.

Is it what you asked?

New changeset 57c66f85942d by Senthil Kumaran in branch '3.4':
Correct the URL in the http.client example. Noted by Evens Fortuné. Closes #21229
http://hg.python.org/cpython/rev/57c66f85942d

Yes. And thanks for the patch. I applied a slight variation of it.
