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 /usr/share/doc/pythonX.Y/html/library if the pythonX.Y-doc package is installed or 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.
