 Hi, let's talk about that how to check if a string contains vowels. Let's make a simple string, for example, Germany, and let's check if this string contains any vowel. Okay, let's check these characters inside our string. Let's use variable C for characters and let's check them inside our string. And our character C will be one of the vowels. So let's make our character to check the occurrences of any vowel inside our string Germany. And we want to find if our string contains any vowel, so we're going to use function any, which will return to us true if our searching string contains any vowel. Okay, let's press enter and of course, as you can see, our string contains few vowels, so the returning value is true. You can also make a simple string, let's call it my string, let's say Paris, Berlin, and you can use the same technique to check if your string contains at least one vowel. Let's say C in my string, C in vowels, you do not need to use checking for vowels, you could also use this technique to look up for other letters, for example, letter A, letter S, letter N and so on. And of course, we can find all these letters inside our string. That's all in this lesson, thanks for watching, bye-bye.
