Change variable name with a modifier (python 2.7) due to limitations

[Dujith]

So for this KNX server (Gira Homeserver) its possible to write your own code, now there are limitations (1 being its Python 2.7 with a fixed library)

And i want to simplify an action, but i'm not sure how. My python knowledge is low and most stuff i just google  

 

Now for the problem:

 

Whenever i make a logic module i first have to specify the inputs and outputs. After that a program generates a py file in which i can enter my own code.

The module i'm making will talk via TCP to a security system and tell me which zones are activated for all kinds of stuff i want todo with KNX (lights, visualization of doors on the touchscreen ect.)

I get that data by a binaire number that tells me the zones activated: https://linustechtips.com/topic/1330742-decoding-a-tcp-response/?tab=comments#comment-14678574 again thanks to @Eigenvektor

 

 

So i made a module that has 10 inputs and 10 ouputs (3 more inputs for the IP, port and trigger) and it generated this:

class Integra10834(hsl20_3.BaseModule):

    def __init__(self, homeserver_context):
        hsl20_3.BaseModule.__init__(self, homeserver_context, "Integra")
        self.FRAMEWORK = self._get_framework()
        self.LOGGER = self._get_logger(hsl20_3.LOGGING_NONE,())
        self.PIN_I_IPADRES=1
        self.PIN_I_POORT=2
        self.PIN_I_ZONE_STATUS=3
        self.PIN_I_ZONE1=4
        self.PIN_I_ZONE2=5
        self.PIN_I_ZONE3=6
        self.PIN_I_ZONE4=7
        self.PIN_I_ZONE5=8
        self.PIN_I_ZONE6=9
        self.PIN_I_ZONE7=10
        self.PIN_I_ZONE8=11
        self.PIN_I_ZONE9=12
        self.PIN_I_ZONE10=13
        self.PIN_O_ZONESTATUS1=1
        self.PIN_O_ZONESTATUS2=2
        self.PIN_O_ZONESTATUS3=3
        self.PIN_O_ZONESTATUS4=4
        self.PIN_O_ZONESTATUS5=5
        self.PIN_O_ZONESTATUS6=6
        self.PIN_O_ZONESTATUS7=7
        self.PIN_O_ZONESTATUS8=8
        self.PIN_O_ZONESTATUS9=9
        self.PIN_O_ZONESTATUS10=10
        self.FRAMEWORK._run_in_context_thread(self.on_init)

At some point i check the binary number to get the zones with this:

                    for x in databin:
                        if x == "1":
                            zones.append(bit)
                        else:
                            if bit in zones:
                                zones.remove(bit)
                        bit += 1

databin being the stored binary number in a string. This way i get the zone number in zones

Now i just have to compare the zone numbers i put into 1 of the 10 pins and trigger the output pin.

But how can i do this in a better way then make 10 if statements?

After doing some more searching it seems i can do something with exec, gonna be a bit hacky but it works 

for y in range(1,11):
	exec "yy = self._get_input_value(self.PIN_I_ZONE" + str(y) + ")"
 

This is then followed by a check in the zones list i made for that value (numbers are unique so can do a simple in statement.)

and with the y i can set the output number to on or off.

 

There prob is a better way todo this, but then i would need to spend alot more time in python

I don't really quite understand why you're trying to do here, but why not use enums. Then you can just do:

 

If i could i would have, but i'm limited on how the KNX server presents its inputs and outputs in python.

When i specify how much inputs and outputs a module will have it generates that code i posted in the first post.

self.PIN_I_ZONE1 being the first one and so on.

Then i need to use self._get_input_value(self.PIN_I_ZONE1) to get the value in that input, and i set an output with self._set_output_value(self.PIN_O_ZONESTATUS1, 1)

Its just how the module works and i cannot change that part sadly.

In the KNX server it look like this. So for a system with 100 zones i can pick out a few i need to switch on lights (Door opens at night so the hallway will come on for example)
