 Hi again, in this lesson, we're going to talk about that how to iterate through the alphabet in Python programming language. We can iterate through the lower case or through the upper case alphabet letters in Python programming language. First, let's make one example with simple iteration using lower case letters. Let's import lower case letters from string module. So we'll say from string import ascii lower case. And let's make one loop and let's use i in our loop to iterate through all the ascii lower case letters. So we'll want to iterate all our alphabet lower case letters. And let's do some simple thing. For example, let's print all those letters. You can use this iteration through the alphabet to do some other things into your program. But I'll make simple example with just printing that letters. Let's print those letters and we will iterate it through the lower case alphabet letters. Let's do the same but with upper case letters. So our code will be same except that we'll import ascii upper case. And we'll also use same for loop and we will change lower case to upper case. And let's again, let's just print those letters. You can do with that iteration something else. It doesn't matter for now. And that's it. That's all for this lesson. Thanks for watching. Happy coding!
