Where to Declare Functions

You've probably noticed that a variable needs to be declared before it's used. For example, the following doesn't work:

print(my_name)
my_name = 'Lane Wagner'
# NameError: 'my_name' is not defined

It needs to be:

my_name = 'Lane Wagner'
print(my_name)
# Lane Wagner

Code executes in order from top to bottom, so a variable needs to be created before it can be used. That means that if you define a function, you can't call that function until after it has been defined.

Assignment

There's a bug! It looks like we are trying to call a function before it was defined! Run the code and read the printed error, then fix it.

You don't need to add any new functions or pass any inputs. Calling a function with empty parentheses is perfectly valid. Pay attention to where main() is being called.
