I Want To Know If We Can Perform Two Different Actions Using For Loop For List

I want to shutdown core1, core2 and bring up core3, core4 while I am working on router1. In the same way I have to bring up core1, core2 and shutdown core3, core4 while working on

Solution 1:

You just need to add a conditional for shutting/non shutting down cores.

router1, router2, = "10.11.12.13", "10.11.12.14"
tunnel1, tunnel2, tunnel3, tunnel4, tunnel5 = "tunnel01","tunnel02","tunnel03","tunnel04", "tunnel05"
core1, core2, core3, core4 = "core01", "core02", "core03", "core04"


routers = [router1, router2]
tunnels = [tunnel1, tunnel2]
cores = [core1, core2, core3, core4]
loopback = "loopback"defnoshut(tunnel, router):
    print('NO SHUTDOWN', tunnel, router)

defshut(tunnel, router):
    print('SHUTDOWN', tunnel, router)

defnoshutcore(core):
    print('NO SHUTDOWN loopback', core)

defshutcore(core):
    print('SHUTDOWN loopback', core)


for r1 in routers:
    # conditional for shutting/not shutting coresif r1 == router1:
        shutcore(core1)
        shutcore(core2)
        noshutcore(core3)
        noshutcore(core4)
    elif r1 == router2:
        noshutcore(core1)
        noshutcore(core2)
        shutcore(core3)
        shutcore(core4)
    print()
    for t1 in tunnels:
        for r2 in routers:
            for t2 in tunnels:
                if r1 == r2 and t1 == t2:
                    noshut(t1,r1)
                else:
                    shut(t2,r2)
        print()

The output will then look like.

SHUTDOWN loopback core01
SHUTDOWN loopback core02
NO SHUTDOWN loopback core03
NO SHUTDOWN loopback core04

NO SHUTDOWN tunnel01 10.11.12.13
