"""Generate Python documentation in HTML or text for interactive use.
|
|
|
|
In the Python interpreter, do "from pydoc import help" to provide online
|
|
help. Calling help(thing) on a Python object documents the object.
|
|
|
|
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 a given port on the
|
|
local machine to generate documentation web pages. Port number 0 can be
|
|
used to get an arbitrary unused port.
|
|
|
|
For platforms without a command line, "pydoc -g" starts the HTTP server
|
|
and also pops up a little window for controlling it.
|
|
|
|
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/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.
