 Hi everyone. In this video, we're going to talk about that how to process a file in Python language. Processing a file consists of these three steps. So every time when you're working with files in Python, you need to follow these three steps. First step is to open a file for reading or writing. And you can do that by using open function. We're going to cover that in some other video. Then after opening a file, you can use that file to read from it or to write something to it. And you can do that by using few functions. First function is read with which you can read just few characters or all characters. Then you can use read line function with which you can read a line of the text from the file or you can read lines. That means that this function is going to read this all file line by line. And finally, if you want to write to the file, you're going to use write function. We're going to discuss about these functions later in some other videos. After reading from the file or writing to the file, we need to close the file. And in order to do that, we're going to use close function. So anytime when we're working with files, we need to open a file, read that file or write to that file and finally close that file. In all these situations, we're going to use these functions. That's all in this tutorial. Don't forget to subscribe to my channel. See you in the next video. Happy coding!
