At the Python interactive prompt, calling help(thing) on a Python object documents the object, and calling help() starts up an interactive help session. Or, at the shell command line outside of Python: Run "pydoc <name>" to show documentation on something. <name> may be the name of a function, module, package, or a dotted reference to a class or function within a module or module in a package. If the argument contains a path segment delimiter (e.g. slash on Unix, backslash on Windows) it is treated as the path to a Python source file. Run "pydoc -k <keyword>" to search for a keyword in the synopsis lines of all available modules. Run "pydoc -p <port>" to start an HTTP server on the given port on the local machine. Port number 0 can be used to get an arbitrary unused port. Run "pydoc -b" to start an HTTP server on an arbitrary unused port and open a Web browser to interactively browse documentation. The -p option can be used with the -b option to explicitly specify the server port. Run "pydoc -w <name>" to write out the HTML documentation for a module to a file named "<name>.html". Module docs for core modules are assumed to be in https://docs.python.org/X.Y/library/ This can be overridden by setting the PYTHONDOCS environment variable to a different URL or to a local directory containing the Library Reference Manual pages. �helpzKa-Ping Yee <ping@lfw.org>z26 February 2001z�Guido van Rossum, for an excellent programming language.

Start an HTML/text server thread, so HTML or text documents can be browsed dynamically and interactively with a Web browser. Example use: >>> import time >>> import pydoc Define a URL handler. To determine what the client is asking for, check the URL and content_type. Then get or generate some text or HTML code and return it. >>> def my_url_handler(url, content_type): ... text = 'the URL sent was: (%s, %s)' % (url, content_type) ... return text Start server thread on port 0. If you use port 0, the server will pick a random port number. You can then use serverthread.port to get the port number. >>> port = 0 >>> serverthread = pydoc._start_server(my_url_handler, port) Check that the server is really started. If it is, open browser and get first page. Use serverthread.url as the starting page. >>> if serverthread.serving: ... import webbrowser The next two lines are commented out so a browser doesn't open if doctest is run on this module. #... webbrowser.open(serverthread.url) #True Let the server do its thing. We just need to monitor its status. Use time.sleep so the loop doesn't hog the CPU. >>> starttime = time.time() >>> timeout = 1 #seconds This is a short timeout for testing purposes. >>> while serverthread.serving: ... time.sleep(.01) ... if serverthread.serving and time.time() - starttime > timeout: ... serverthread.stop() ... break Print any errors that may have occurred. >>> print(serverthread.error) None r Nc @ s( e Z d Z d d � Z d d � Z d S)z!_start_server.<locals>.DocHandlerc S sx | j j d � r d } n d } | j d � | j d d | � | j � | j j | j | j | � j d � � d S) z�Process a request from an HTML browser.
