+@subsection Python Commands
+@cindex python commands
+@cindex commands to access python
+
+@value{GDBN} provides one command for accessing the Python interpreter,
+and one related setting:
+
+@table @code
+@kindex python
+@item python @r{[}@var{code}@r{]}
+The @code{python} command can be used to evaluate Python code.
+
+If given an argument, the @code{python} command will evaluate the
+argument as a Python command. For example:
+
+@smallexample
+(@value{GDBP}) python print 23
+23
+@end smallexample
+
+If you do not provide an argument to @code{python}, it will act as a
+multi-line command, like @code{define}. In this case, the Python
+script is made up of subsequent command lines, given after the
+@code{python} command. This command list is terminated using a line
+containing @code{end}. For example:
+
+@smallexample
+(@value{GDBP}) python
+Type python script
+End with a line saying just "end".
+>print 23
+>end
+23
+@end smallexample
+
+@kindex maint set python print-stack
+@item maint set python print-stack
+By default, @value{GDBN} will print a stack trace when an error occurs
+in a Python script. This can be controlled using @code{maint set
+python print-stack}: if @code{on}, the default, then Python stack
+printing is enabled; if @code{off}, then Python stack printing is
+disabled.

+At startup, @value{GDBN} overrides Python's @code{sys.stdout} and

+@subsubsection Basic Python
+
+@cindex python functions
+@cindex python module
+@cindex gdb module
+@value{GDBN} introduces a new Python module, named @code{gdb}. All
+methods and classes added by @value{GDBN} are placed in this module.
+@value{GDBN} automatically @code{import}s the @code{gdb} module for
+use in all scripts evaluated by the @code{python} command.
+
+@findex gdb.execute
+@defun execute command
+Evaluate @var{command}, a string, as a @value{GDBN} CLI command.
+If a GDB exception happens while @var{command} runs, it is
+translated as described in @ref{Exception Handling,,Exception Handling}.
+If no exceptions occur, this function returns @code{None}.
+@end defun
+
+@findex gdb.get_parameter
+@defun get_parameter parameter
+Return the value of a @value{GDBN} parameter. @var{parameter} is a
+string naming the parameter to look up; @var{parameter} may contain
+spaces if the parameter has a multi-part name. For example,
+@samp{print object} is a valid parameter name.
+
+If the named parameter does not exist, this function throws a
+@code{RuntimeError}. Otherwise, the parameter's value is converted to
+a Python value of the appropriate type, and returned.
+@end defun
+
+@findex gdb.write
+@defun write string
+Print a string to @value{GDBN}'s paginated standard output stream.
+Writing to @code{sys.stdout} or @code{sys.stderr} will automatically
+call this function.
+@end defun
+
+@findex gdb.flush
+@defun flush
+Flush @value{GDBN}'s paginated standard output stream. Flushing
+@code{sys.stdout} or @code{sys.stderr} will automatically call this
+function.
+@end defun
+
+@node Exception Handling
+@subsubsection Exception Handling
+@cindex python exceptions
+@cindex exceptions, python
+
+When executing the @code{python} command, Python exceptions
+uncaught within the Python code are translated to calls to
+@value{GDBN} error-reporting mechanism. If the command that called
+@code{python} does not handle the error, @value{GDBN} will
+terminate it and print an error message containing the Python
+exception name, the associated value, and the Python call stack
+backtrace at the point where the exception was raised. Example:
+
+@smallexample
+(@value{GDBP}) python print foo
+Traceback (most recent call last):
+ File "<string>", line 1, in <module>

+@value{GDBN} errors that happen in @value{GDBN} commands invoked by Python
+code are converted to Python @code{RuntimeError} exceptions. User
+interrupt (via @kbd{C-c} or by typing @kbd{q} at a pagination
+prompt) is translated to a Python @code{KeyboardInterrupt}
+exception. If you catch these exceptions in your Python code, your
+exception handler will see @code{RuntimeError} or
+@code{KeyboardInterrupt} as the exception type, the @value{GDBN} error
+message as its value, and the Python call stack backtrace at the
+Python statement closest to where the @value{GDBN} error occured as the
+traceback.
