Help copying a column from a csv to another file with some extras
#1
Hello,

I need to copy the contents of a .csv, that gets dumped from SQL each night to a folder location on my Ubuntu server that contains 100s of IP addresses to an area within a .conf file. Well I'm happy to create a new file rather than try and open an existing file and insert.

I'm a novice at Python, but getting this working will help. VScode is amazing to.

The csv puts all the IP addresses on the first column:

ip_address
192.168.0.1
192.168.0.2
192.168.0.3
192.168.0.4 
ect...
And I need it to put into a file called something like routers.conf like this on row 2, but I need it be formatted like below and include the " instead of 'around the IP, add the :161 etc and inject into row 2 and replace what is there. Plus add the rest of the config.

[[inputs.snmp]]
  agents ["192.168.0.1:161","192.168.0.2:161","192.168.0.3:161","192.168.0.4:161"]
  version = 2
  community = "publicblah"
  interval = "120s"
  timeout = "5s"
  retries = 0
Could Python do this?

I'm currently using this to open and view it:

    with open("ip.csv", 'r', encoding='utf-8-sig') as infile:
    reader = csv.reader(infile, delimiter=" ")
    header = next(reader)
    print(header)
I've been reading through - https://realpython.com/python-csv/

I did have a play with the outfile = open and outfile.write options, but get lost as this just writes a new .csv.

Any help to copy this data, format it, and create a new file with the addition config file would be most welcome.
