 Hi, in this lesson, we're going to talk about that how to open a file with its default program in Python. For example, let's say that we have a JPEG image and that we want to open that image inside default program with usage of Python. What we need to do is to import OS module, then let's change our current working directory to directory in which we have our image. Our image is stored inside files directory on a C drive. And now we want to open that picture, that image in its default program. So we're going to call method start file and inside this method as an argument, we're going to put the name of our JPEG image in our case that image is miami.jpeg. Okay, let's check it if I want to open this folder. I will see that I have that picture called miami.jpeg. So we want to open our picture from a default program in Windows. Now let's press enter and our image is opened inside Windows Photo Viewer because it's default program for opening image files with usage of start file method of OS module. You could also open other files with other extensions on other default programs in Python programming language. That's all in this lesson. Thanks for watching, bye-bye.
