 Hi again. In this lesson, we're going to talk about that how to work with Python in interactive mode in Command Prompt. Okay, let's make a simple file, a simple function. Let's call it, for example, get the city. And let's provide as an argument city name. And what we want to do is to print that city name. Okay, now let's save our file as, for example, cityname.py. This file is stored inside Python 3632 folder. Let's save it. And now let's go to the command prompt. Let's find our file inside directory Python 3632. Okay, let's find it. Okay, here we have it cityname.py. Now we want to work with this file in interactive mode. So we're going to use command py minus i minus i. With minus i, we're telling to Python that we want to work in interactive mode with our city name file. Okay. Now we have here a function getCity. And if we want to call it, we need to provide its name. So inside our function as an argument, we're going to provide a name. Let's call our function in interactive mode and let's provide city name, for example, Chicago. Okay. And let's press enter and we're going to get printed result Chicago. So with calling command py and minus i and putting the name of your file, you're going to work with that file in interactive mode, which means that you can change and add some new things to your code and work with your code inside this file further. That's all in this lesson. Thanks for watching. Bye-bye.
