Testing Python-script statements

In privileged EXEC mode, enter the python command to access the Python shell.

device# python

[GCC 4.8.2] on linux
Type "help", "copyright", "credits" or "license" for more information.

Note that the device# prompt changed to a >>> Python prompt:

Enter the script statements one at a time, verifying that they run as expected.

>>> cmd_config_ve = CLI('configure \n interface ve 101-103')
!Command: configure 
 interface ve 101-103
