 Hi again, in this lesson we're going to talk about that how to substitute string with a string template in Python programming language. First, let's import module string to work with string templates. Then let's make a variable, let's call it city, let's call our module string and method template to make our template. Let's make template, our identifier in template will begin with dollar sign. Let's make identifier, for example city name and let's say that our city will be in Texas and now let's substitute our city name name with our new provided name. We're going to call our string and provide substitute method and we'll provide our variable with value for example Houston and as you can see our identifier will be changed with our new city name variable which is Houston, you can also change at any time your variable name let's say Austin or I don't know maybe Dallas and so on, you get the point. That's all in this lesson, thanks for watching, see you in the next lesson, bye.
