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 -n <hostname>" to start an HTTP server with the given hostname (default: localhost) on the local machine. 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. Combine with the -n and -p options to control the hostname and port used. 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.

If the module *is* found but an exception occurs, it's wrapped in an ErrorDuringImport exception and reraised. Unlike __import__, if a package path is specified, the module at the end of the path is returned, not the package at the beginning. If the optional 'forceload' argument is 1, we reload the module from disk (unless it's a dynamic extension).c s g | ]}|� � d �r|�qS )r )ra )rq �m�r r r � <listcomp>Q s z safeimport.<locals>.<listcomp>Nr r )r r� �builtin_module_names� __import__r� r� rP � SyntaxErrorr� � issubclass� ImportErrorr( r r< �AttributeError) r � forceloadr� ZsubsrH r� r� rI r� �info�partr r� r � safeimport= s. r� c @ sf e Zd Zej�ddejdd� �Zd dd�Z d dd�Z e Z Z Z Z ZZe�d �fd d �ZdS )�Doc� PYTHONDOCSz%https://docs.python.org/%d.%d/libraryNr c G s� ||f| }zFt �|�r$| j|� W S t �|�r:| j|� W S t �|�rP| j|� W S W n tk rf Y nX t �|�r|| j |� S | j |� S )z%Generate documentation for an object.) r r* � docmoduler+ �docclassr, � docroutiner� rj �docdata�docother)r> r r( �argsr r r �documents s z Doc.documentc G s* d|odt |� t|�jf }t|��dS )z+Raise an exception for unimplemented types.z.don't know how to document object%s of type %s� N)�repr�typer% r} )r> r r( r� �messager r r �fail� s �zDoc.failZstdlibc C s� zt �|�}W n tk r& d}Y nX tj�d| j�}tj�|�}t |t t��r�|j dksz|� |�r�|� tj� |d��s�|j dkr�|� d�r�d|�d�|j �� f }q�tj� ||j �� d �}nd }|S ) z*Return the location of module docs or None� (built-in)r� ) �errno� exceptionsZgcZimp�marshal�posix�signalr �_threadZ zipimportz site-packages)z xml.etreeztest.pydoc_mod)zhttp://zhttps://z%s/%s�/�.htmlN)r � getabsfiler} r �environrv r� r r rk r� r% ra r!

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.monotonic() >>> timeout = 1 #seconds This is a short timeout for testing purposes. >>> while serverthread.serving: ... time.sleep(.01) ... if serverthread.serving and time.monotonic() - starttime > timeout: ... serverthread.stop() ... break Print any errors that may have occurred. >>> print(serverthread.error) None r Nc @ s e Zd Zdd� Zdd� ZdS )z!_start_server.<locals>.DocHandlerc S sX | j �d�rd}nd}| �d� | �dd| � | �� | j�| �| j |��d�� dS ) z�Process a request from an HTML browser.
