Previously, we've learned about data types, specifically strings (like "Hello") and integers (like 42).

Let's see if you remember which type the value 2077 belongs to?

Let's look at the + symbol again. We know it adds integers: 5 + 10 gives 15.

But what do you think + does if you use it between two strings? For example:

"Hello" + " " + "World"

What might the result look like?

When you use + with strings, Python joins them together, end-to-end. This joining process is called concatenation.

So, "Hello" + " " + "World" results in the single string "Hello World".

Is the operation 100 + 50 an example of concatenation? Why or why not?
