$1.$ Create a list, called port$\_$list, It shall include all ports between $2205-2214.$

a$.$ Create a loop that iterates through each list element

i$.$ Use the function len$()$ to stop the loop

ii$.$ Print $$port$,$ list position # and port number of each list item

$1.$ Example..... Port $12205$

$2.$ Create a program that reads from a list of port numbers to login to network devices.

a$.$ Create a list called port$\_$list that contains ports $2205-2214$

b$.$ Create a for loop that uses the len$()$ of port$\_$list as stop point

i$.$ Loop shall connect to each device in port$\_$list.

c$.$ Create s dictionary named cisco that contains

i$.$ Device$\_$type

ii$.$ Ip

iii. Username

iv$.$ Password

v$.$ Port $($from port$\_$list$[])$

d$.$ Connect to each device in port$\_$list

$3.$ Conditionals

a$.$ If statements with the less than operator to overwrite the device type.

b$.$ Use an if statement to prevent attempts at port $2205$

i$.$ Use the continue statement

$4.$ Exception Handling

a$.$ Import Netmiko authenticaton and timeout exceptions

i$.$ Don$$t forget the general exception Clause

b$.$ Use a try and exept block to catch exceptions so loop continues to operate

i$.$ Use a print statement to notify user that an error has occurred.

$5.$ Testing

a$.$ Add a conditional that sets the password to $$CISCO$$ for port $22013$

b$.$ Add an invalid port to the list, somewhere before the last element.
