 Hi again, in this lesson we're going to talk about that how to list all files of a directory in Python programming language. What we want to do in this example is to list all files into directory images on C drive. Okay, first what we need to do is to use OS module and import from OS module walk method. Okay, now we want to call our function walk on our folder which is images on C drive and we want to loop through certain informations of our directory. First we want to look for a path of our directory. We want to look for names of our directory and of file names. So we will use for loop to loop all this and now what we want to do is to list all files inside our directory. Our directory has one file inside its folder and few files inside its subfolder. So also we want to list files inside our subfolders. Okay, so we'll use print and to print those files and we want to print all files of our directory to the screen. And after I press enter we'll see that inside our folder and its subfolders we have three pictures. First is Nebraska.jpeg, second is Austin.jpeg and the last one is Las Vegas.jpeg. So that's all in this lesson. Thanks for watching. Happy coding.
