 A &#8220;line&#8221; of a text file is just what you think it is&nbsp;&mdash;&nbsp;a sequence of characters delimited by a carriage return. Of course, it can&#8217;t really be that simple, can it? Text files can use several different characters to mark the end of a line. Some use a carriage return character, others use a line feed character, and some use both characters at the end of every line. Python handles all of these cases automatically, so you can say, &#8220;Hey, I want to read this text file one line at a time&#8221; and it will Just Work.
