In an earlier video, we saw how we can't use the plus operator between an integer and a string because they're different data types. But what happens when we try to operate with an integer and a float instead, let's find out. Error-free, Python has no problem performing this operation. But what's up with that, aren't integer and a float two different data types? They sure are but there's a lot happening under the hood here. Behind the scenes the computer is busy automatically converting our integer seven into a float seven. This lets Python then add together the values to return results that is also a float. We call this process, implicit conversion. The interpreter automatically converts one data type into another. We've called this out before, but it's worth highlighting again that Python operations aren't just restricted to numbers. You can also use the plus operator to add together strings. This lets you do things like create sentences from individual words. Just don't forget to add spaces to each words. Otherwise, the computer will run them all together. So what if you really want to combine a string and a number, is it possible? It sure is but only with an explicit conversion. In Python, to convert between one data type and another, we call a function with the name of the type we're converting to. Let's see how this works. Now, things are getting a little bit more complex. Let's take a moment to unpack this to make sure it all makes sense. In this script, we're first calculating the area of a triangle, and when printing it we're adding it to a string. To do this, we need to call the STR function to convert a number into a string. Let's execute it and check out what happens. Our number got converted to a string and print it together with the message. We've learned a little bit about variables, values, expressions, and conversions. Next up, we've got a practice quiz to help you solidify your knowledge. As always, take your time and review the content if you need. You've totally got this. I'll see you in the next video once you're finished.
