I am using python 3.6.5 on Ubuntu.
I want to use the data from a csv file that contains a vpn number, ip address and gateway address to assign variables and then use those variables in nmcli commands to create vlans on a linux box.
I have accomplished the reading of the csv file and assigning the variables. I can print the values without issue.
I have accomplished calling subprocess.call to run the nmcli commands. However, The variables I defined in python are not being recognized in the nmcli commands.
I created a loop to assign each vlan, ip address and gateway address variable to run with each set of nmcli commands.
The nmcli commands have been run manually with actual values for each of the variables without issue.
Example of command:
subprocess.call(["nmcli”,“connection”,”add”,”type”,”vlan”,”con-name”,”${VLAN_NAME}”,”dev”,”${INTERFACE}”,”id”,”${VLAN_NUMBER}"], shell=True)

Not sure why the variables are not being recognized.. They are not recognized if I drop the shell=True also.
