有没有一种方法可以在python中使用for循环在每次迭代中对一个项执行不同的操作

Question

我试图在每次迭代中对一个项目执行不同的操作。用python帮助我完成下面的代码

router1 = "10.11.12.13"
router2 = "10.11.12.14"


tunnel1, tunnel2, tunnel3, tunnel4 = "tunnel01","tunnel02","tunnel03","tunnel04"

router = [router1, router2]
tunnel = [tunnel1, tunnel2, tunnel3, tunnel4]

for each in router:
    for eachtunnel in tunnel:


#Here in the first iteration I have to bring up tunnel1 on router1 and shut remaining tunnels on both router 1 and 2.

#In the second iteration I have to bring up tunnel2 on router1 and shut remaining tunnels on both the routers.

它应该持续到8个迭代，其中只有一个隧道是向上的，其余的是向下的。你知道吗

在本例中，我将每个路由器的隧道数设为4，但可能会有所不同。请建议我如何才能做到这一点。你知道吗

Answer 1

这个怎么样：

routers = [router1, router2]
tunnels = [tunnel1, tunnel2, tunnel3, tunnel4]

# Assuming everything is down at the beginning

for router in routers:
    for tunnel in tunnels:
        up(router, tunnel)
        # do stuff
        down(router, tunnel)

为了便于阅读，我对变量名做了一些修改。你知道吗
