Scripting: variable data types 

Just an OpenSSH client :)

Not at this time.

Thank you for pointing that out, that's an interesting nuance.

@@mikrotik I'll add another interesting observation. If we :put the result of a function that should be returns a "nothing", we will see the "nil". Moreover, inside the function itself it will still be a "nothing", and when substituting the return in the :put commanf, we will already see an "nil" :local testFunc do={ :local var; :put ("Inside function is: ".[:typeof $var]); :return $var; }; :put ("Outside function is: ".[:typeof [$testFunc]]); Result: Inside function is: nothing Outside function is: nil I think type damage occurs in the process of substituting using square brackets. This nuance causes another problem: The :nothing command is designed to produce the data type "nothing" and does it successfully. But to use this command in a script, it needs to be wrapped in square brackets so that the value is substituted, and this process convert it to the "nil". :put [:typeof [:nothing]]; Result: nil We get that the system has a command that in practical form cannot produce the intended result. I wrote a ticket about this problem, but support did not accept the arguments. P.S. For example: A simple method to substitute a real "nothing" into an expression is :put [:typeof (:)]; A simple method to substitute a "nil" into an expression is :put [:typeof []];

What would you do in python that you can't in RouterOS?

At that point, you'd get people wanting to have JavaScript as well, and Go, and Rust and because not everyone likes Python. I think it's best to just stick to the DSL they have created for RouterOS and if you really want to use Python, write a wrapper and run it in a container or something.

@@mikrotik lots of people know python and it's well documented. so what would you do? save time by not having to learn another language.
