 Hi, let's talk about how to check if a string contains vowels by using regular expressions. Because we want to use regular expressions in Python, we need to import regular expression module and then we want to search if our string has any vowel inside it. So we're going to use search method and inside it we'll put inside square brackets vowels and next we will put comma and our string. For example let's say that our string is sky so we want to search with usage of regular expressions if word or string sky contains any of these strings or any of these characters any of these vowels. Okay and as you can see we couldn't find any vowel inside our word so with usage of regular expression we can see that this word doesn't contain any vowel. Let's use again regular expression and let's search if our new string contains again vowel. Let's make a string for example London. We could also put a lot of other characters here but I'm working with just one word to make it simple. Let's search. Okay let's press enter and as you can see now with usage of regular expression we've found that our string contains vowels. The first bounded vowel is O so this string does contain at least one vowel. That's all in this lesson. Thanks for watching. Bye bye.
