Loop thru textfile, change 3 variables for every line

[j.crater]

Hi,
in a nutshell, you probably want to iterate through all the lines your file. Then you would split the string (line) into 3 substrings (your variables) and store the 3 substrings in 3 variables.

with open(data_txt, 'r') as f:  #open the file
    for line in f:  #iterate through every line of a text file
        split_string = line.split()  #split the line in a text file into substrings, in this case stored in a list "split_string"
        vlan= split_string[0]  #access first element in "split_string"
        vlanname= split_string[1]  #second element..
        subnet = split_string[2]  #third element...
        
        # here I guess you run your commands with vlan, vlanname and subnet

Does this help?
