python

Launches an interactive Python shell, with an option to launch a Python script.

Syntax

python [ python-statement | python-script-filename ] [ script-arguments ]

Parameters

python-statement: Must be a valid python interpreter argument.
python-script-filename: Runs a Python script file. Valid values range from 4 through 32 characters (including the .py extension). The first character must be alphabetic.
script-arguments: Passes one or more arguments defined in the script.

Modes

Privileged EXEC mode

Usage Guidelines

This command is available only to users with admin-level permissions.

Entering python—with no additional parameters—launches an interactive Python shell.

Entering python python-statement launches an interactive Python shell and runs a valid python-statement that you enter. For example, entering python -h invokes the Python shell and displays Python options and arguments.

Entering python python-script-filename launches an interactive Python shell and runs the Python file. (To make a Python file available to this command, copy the Python file to the flash:// location on the device, using the copy command.)

Note the following divergence between SLX-OS CLI syntax and Python syntax:

Although in general, SLX-OS CLI syntax is not case-sensitive, Extreme convention is to use lower-case.
Python syntax is case sensitive.

To exit the Python environment and return to the CLI, enter either:

exit()
Ctrl-D

Examples

The following example launches the Python shell and then both assigns an SLX CLI operational command to a Python variable and runs that command.

The following example (partial) launches the Python shell to run a Python script-file.
