Need help with Pexpect for device config

Hello,

I am still learning Python for networking :) but can't figure this out. If someone can help would really be thankful. My goal is to pull the 'show run' from the list of devices and create the list of VLANs for every device. Script successfully running show run but not the VLAN configuration. Most certainly it's something wrong with for loop. Any ideas? Thank You
