 Hi again, in this video we are going to talk about that how to count number of occurrence of a character in a string in Python programming language. First let's make a string, let's call it maybe Canadian cities and let's put few cities inside our string. Let's add Toronto, Montreal and Vancouver. Now if we want to check occurrence of some of those characters, we'll use method count and we'll put as an argument the letter which we want to check its number of occurrence in this string. So for example let's choose letter O and let's count number of currency. Number of currency is 5 so we have 1, 2, 3, 4, 5 times letter O. Let's check for example what will happen if we want to check number of currency of some letter that don't exist in our string. For example letter X we will get that number of currency of letter X is 0. Okay and for practice we could maybe choose just another one letter, I don't know maybe letter R and the number of occurrence of our letter R R number 3. That's all in this video. Thanks for watching. See you in some next video. Bye-bye.
