[Tutor] Turning a "script" into an "application"

[Bill Mill]

Christian,

I'm not really sure what you're asking. Do you have more concrete questions?

It seems to me that, instead of messing around with threads, you may
want to write an entirely seperate script to control the network
script. Pseudocode:

##############
#network_script_controller
#############
while 1:
    actions = {'1': send_foo_to_network_script,    #this is a function reference
        '2': send_bar_to_network_script                 #so is this
        #and whatever else menu options you want
        }
    print "Enter one to change foo, or two to change bar"
    msg = raw_input('>')
    actions[msg]()

#############
#network_script
############
while 1:
    do_my_processing_loop()
    check_for_new_messages()

And you could simply use sockets for communication between the two. Is
that something like what you're looking for?

Peace
