Hello friends and welcome back. In this part I will tell you about how to use next matter and is a TTY. It returns a Boolean value. If it it will show true if the file is connected to TT via light device and false if it is not. And next, it returns the next nine from the last offset means it is used when the file is used as a traitor. The method is called repeatedly.

This method returns the next input line or raises top iteration at elf when the file is open for reading behavior is undefined when opened for writing. Open idle Create a file let's check it just gonna do to TTY like device or not False, as I told it will show false if the file is not connected to TTY like device. Now, I'm going to perform next how to use next method. Open File, all right, line F dot next No x except dark clothes. Oh indentation problem. see nothing is printed here.

It may be dead file maybe empty. Let's check it So Till now I completed our next method as a divine method, read read line, right. So, for tillow keep learning, keep growing. Love Python and happy coding
