 Let's talk how to check if a string contains a number by using regular expressions. Because we want to use regular expressions, we need to import regular expression module. Then we want to search if our string contains any number. So we're going to call search method of regular expression module and we want to make a pattern. Our pattern is going to use numbers from 0 to 9 and let's define a string to check if this string contains any of those numbers. For example, let's say Beverly Hills 82010, and let's check if our string contains any of number, any number. Okay, let's press enter and as you can see, we found it first number that is 9 and we don't need to check anymore because we find at least one number here. We could also do that, search and matching this pattern by using simple form for numbers. We could just type that we want to check for a currency of numbers from 0 to 9. We don't need to write all these numbers and let's use same string again to check the currency of any number inside our string. Okay, let's press enter and again, we're going to get the same result because this string contains numbers. First number is number 9. That's all in this lesson. Thanks for watching. Bye bye.
