How I do this:

a = file.readline()
b = # save the position (line) read from the file
while a != "TEST":
   a = file.readline

c = # continue reading the file from the position b

??

It's possible do this???

Why don't you try and do it and find out? If you can't do it, tell us what you have tried and where you are having problems.

The piece of code that I commented. I do not know how to do

If I didn't undurstand it correct, please correct me, don't be angry.

If you want to save each line to the variable, you can use a sequence Like this:

try:
    #First of all, let's open the file
    file = open('file_name.txt')

    #Create a sequence, where we can write down all line from the file
    each_lines = []

    #Iterate the file and write down each line
    for each_line in file:
        each_lines.append(each_line)

    #Now, you can do all you want to do with each line...
except IOError:
    print('This is a problem with your file')

I use exceptional handling because I want to get errors, which occurs in runtime... If it's didn't occur, the program will continue... You can use an alternative of try/except statment, OS standart library, like this:

import os

if os.path.exists('file_name.txt'):
    #First of all, let's open the file
    file = open('file_name.txt')

    #Create a sequence, where we can write down all line from the file
    each_lines = []

    #Iterate the file and write down each line
    for each_line in file:
        each_lines.append(each_line)

    #Now, you can do all you want to do with each line...
else:
    print('Your file isn\'t exist')
