I need help with this python code i need step by step with answer so i can understand the step and how to do it thank you!

Create a python script that will log into the AT&T router server $($route$-$server.ip$.$att.net$)$ and $......$

ask for the name of the route server as an argument

pull the username and password from a file $($file does not have to be encrypted$)$

stop 'paging' on the display

save output to a file

print the count of CIDR blocks

print the count of all CIDR blocks by the first octet. For example $1.$x$.$x$.$x has Y CIDR blocks, $2.$x$.$x$.$x has Y CIDR blocks, etc...

Hint: 'show route all $12\mathrm{.}0\mathrm{.}1\mathrm{.}0/16\text{'}$ in the AT&T route server can provide the information needed.
