Sure, I'll be happy to help.

The error you are getting means that you are trying to combine a string (a sequence of characters) with a float (a decimal number) using the `+` operator, which is not allowed in Python. For example, `"The average is: " + 3.0` will give you the same error, because `"The average is: "` is a string and `3.0` is a float.

To fix this error, you need to __convert the float to a string__ using the `str()` function before concatenating it with the other string. For example, `"The average is: " + str(3.0)` will work fine, because both operands are strings.

So, in your code, you need to change the last line to:

```py
print("The average is: " + str(result))
```

This way, you can print the result without getting an error.

I hope this helps you understand the error and how to fix it!
