i have a text file with some content, i need to return that content in order to print it and some update
I used he absolute path to be sure the path is correct
file = opren(r'path\to\file.txt','r')
print(file.read()) works fine, it returns the whole content. But whene i try to return the content in a form of list using
print(file.readlines()) , it returns nothing; an empty list .
my debuging was like this ,i tried to
len(file.readlines()) to make sure, it is indeed return nothing, and it does. it prints 0
the key here is file pointer if you open you file you will notice the flashing sign.(that is your mouse cursor).

solution 1(bad practice) : open and close after every action
solution 2: change the file pointer
file.seek(0)# 0 will set the pointer at the start,then use
