A lot of confusion and I can't seem to solve this issue

This is working fine but how do you loop through all the ip which is in a file?

When you do this it will just be one big string object,that you can not iterate over.
Have to spilt it up for this to work.

ip_list = file_read.read()

Let say this is content.
ip_lst1.txt

Output:
118.31.106.59
118.31.106.59
118.31.106.59

Can just iterated over file object,no need to read()(and split it up).

import requests

with open('ip_lst1.txt') as f:
    for ip in f:
        ip = ip.strip()
        print(ip)
        response = requests.get(f"http://{ip}:9200/_cat/indices")
        print(response.text.strip())

Output:
118.31.106.59
green open .geoip_databases vtWge-U1SLefV6CuavYxCQ 1 0 40 40 37.7mb 37.7mb

Doing most task will be will be a struggle if you don't spend time learning📜 basic Python.

I'm learning python for beginner but it might take some time for be to be professional like you.. But I'm getting this error
