Hi @Justin Kinney (https://teamtreehouse.com/justinkinney),
when you define a function with an argument list, the caller of this function then can pass in the needed arguments between the parentheses. Let's say somebody uses your function. Therefore you should declare the function with an argument. You can handle that argument(s) then within the logic of your function. 
Example:
```python
import random
def random_num(number):       
    return random.randint(1, number)  #This takes the given argument and uses it as a parameter
```
the return just says, that you return something back to the function when it get's called. You could for example pass the value to a variable if you wanted. 
python
variable = random_num(5) #calls the function and assigns the return value to the variable

which would call your function with 5, so that your function returns random.randint(1, 5) and assigns it to the variable. 
Got it? Maybe I explained it a little too complicated. If you still need help just asked :-)
