The Cisco IOS commands $$show vlan$$ and $$show cdp neighbor$$ have a lot of header and trailer information. See $$show vlan brief$$ for vlan expectations

You will create two programs.

one to execute commands and print the output

login to a device

retrieve the output of show vlan, and show cdp neighbors

pass output of commands to functions

print the function returns

the other will have only the two functions

remove$\_$header$()$

remove$\_$trailer$()$

Both functions will require two arguments.

String data from show command

Delimiter

Each function will need to perform the following

Split the string to a list, using newline character$($

$)$ as delimiter.

Find the index position of the delimiter

Slice the list based on the delimiter$$s index position

Convert the list back to the string using code similar to this:

Mystring $=$

For x in list:

Mystring $+=\backslash$ n$+$ x

#mystring $=$ mystring $+\backslash$ n$+$ x

Return the list to the original function call
