-  We are dealing with **scoping** here which is an important concept for programmers to understand. Why did we bother to create the variable `output` in the main part of the program, and **initialise** it as a blank string, when we could have just created it within the `take_picture()` function? The answer is that if we only created it within the `take_picture()` function, once the function finished executing, the variable would no longer exist. By declaring that we are talking about the `global` version of the `output` variable, we are telling the program that we want to use the variable `output` which we created in the main part of the program, and to save the generated filename. We need to save the filename to be used again because it is not just used in the `take_picture()` function, but in other places within the program.

This means that once the function exits, the variable `output` with the location of the saved picture will still exist. We need to have a permanent record where the picture was saved because it is used in other places within the program.
