    ... yup, particularly for non trivial network related stuff.

Neither here nor there, but I just learned the ";" character command 
today for the Julia REPL, and got to thinking that python should have a 
similar way for the REPL to drop into "shell" mode for system commands.

So, I might code a clear screen in python:

def cls()
    rc = system("clear")

or in Julia

function cls()
    run(`clear`)
end

...  but on Julia we can also do this:

; clear

On the Julia REPL the ";" character drops the julia prompt into shell. I 
think the IDLE REPL should have a system shell mode. What say you?
