How to assign variable for every line in txt seperately in Python?

I have a text file that with multiple lines and I’m trying to assign turn every line into a string and assign them into a variable separately. The code looks something like this at the moment:

with open('config.txt', 'r') as f:
    file_name = ''.join(f.readlines()[0:1])
    Runstart = ''.join(f.readlines()[1:2])
    Runend = ''.join(f.readlines()[2:3])

But it doesn’t read anything after the first line. What am I doing wrong here and how do I fix it? The goal is to give a name for every line. Alternative methods are welcomed.

Thanks.

>Solution :

You don’t need all these slices and indices. Just use readline:

with open('config.txt', 'r') as f:
    file_name = f.readline()
    Runstart = f.readline()
    Runend = f.readline()
