Question

Could someone please point me in the right direction?

I am trying to swap between multiple infinite control loops within python. I need to kill a loop and then select a different loop upon request from an outside source(hopefully web interface), not based on an internal condition. I understand this is a vague question but I need a general point in the right direction to get me started, I have looked at exceptions, signals and threading but I am struggling to find what would be the “correct” way to do this.

Please note, I work in electronics not programming so sorry if this sounds stupid. Also if this is completely the wrong way to go about the problem could someone advise me on the correct method.

I can provide more info/explanation if someone can help me and post code if needed but I think it’s pretty irrelevant at the moment due to the vagueness of the question.

Thanks

The easiest way is probably just read some file which controls your loops …

while True:
    #loop1
    while True:
       #do something
       with open("some.file") as f:
            if f.read() == "loop2":
                break
     #loop2
     while True:
        #do something
        with open("some.file") as f:
            if f.read() == "loop1":
                break

then just put which loop you want in “some.file” (however you want … web interface etc)
