Perchè sono i file sono iteratori e sono più efficienti

"The xreadlines() method of file objects, introduced in Python 2.1, is
no longer necessary because files now behave as their own iterator.
xreadlines() was originally introduced as a faster way to loop over
all the lines in a file, but now you can simply write for line in
file_obj. File objects also have a new read-only encoding attribute
that gives the encoding used by the file; Unicode strings written to
the file will be automatically converted to bytes using the given
encoding."
