If this is your first time using Python, you should definitely check out the tutorial on the Internet at https://docs.python.org/{0}/tutorial/. Enter the name of any module, keyword, or topic to get help on writing Python programs and using Python modules. To quit this help utility and return to the interpreter, just type "quit". To get a list of available modules, keywords, symbols, or topics, type "modules", "keywords", "symbols", or "topics". Each module also comes with a one-line summary of what it does; to list the modules whose name or summary contain a given string such as "spam", type "modules spam". z%d.%dr )r� r� r r r� )r> r r r r � s z Helper.intror} �P c C s� t t|��}|| }t|�| d | }x�t|�D ]z}xht|�D ]\}|| | }|t|�k r@| j�|| � ||d k r@| j�dd|d t|| � � q@W | j�d� q2W d S )Nr r� r )r �sortedr r� r� r� ) r> �items�columnsr� Zcolwr �rowr rk r r r r � s (z Helper.listc C s | j �d� | �| j�� � d S )NzN Here is a list of the Python keywords.

Show text documentation on something. <name> may be the name of a Python keyword, topic, function, module, or package, or a dotted reference to a class or function within a module or module in a package. If <name> contains a '{sep}', it is used as the path to a Python source file to document. If name is 'keywords', 'topics', or 'modules', a listing of these things is displayed. {cmd} -k <keyword> Search for a keyword in the synopsis lines of all available modules. {cmd} -n <hostname> Start an HTTP server with the given hostname (default: localhost). {cmd} -p <port> Start an HTTP server on the given port on the local machine. Port number 0 can be used to get an arbitrary unused port. {cmd} -b Start an HTTP server on an arbitrary unused port and open a Web browser to interactively browse documentation. This option can be used in combination with -n and/or -p. {cmd} -w <name> ... Write out the HTML documentation for a module to a file in the current directory. If <name> contains a '{sep}', it is treated as a filename; if it names a directory, documentation is written for all the contents. )r� r� )�getoptr? r� r r� r@ r� r� r r �existsr� ry r� r r� r� r r� r] r� r� r r� )r� r� Zoptsr� ZwritingZ start_serverr� rV rj �opt�val�argrH r� r r r �cliR s` " r� rC )NN)r )r )r� r N)r� r N)r )r N)rl )r )Zr( rY rZ rR rO Zimportlib._bootstrapr� Z importlib._bootstrap_externalZimportlib.machinery�importlib.utilr r� r r. r� r r r� ri r� Z urllib.parser) rK � collectionsr �reprlibr � tracebackr r r r$ r) r- r/ r3 r � IGNORECASEr4 r5 r: r? rC rN rd re rw r{ r� r� r? r� r� r� r� r� r� re rf rw ry rx r} r r| r� r� r� r� r� r. r� r� r� r� r" r� r� r� r rA r@ rk r� r� r� r� r� r� r% r r r r �<module>( s� ' 0<* ; p" , = n% U
