# I cant understand what is it even asking me, why is it this complicated?

Recently I’ve started to learn python, I don’t have any background and I am totally new to it.

The first lessons very pretty easy to pick up, but with the number rising, I find the course to be quite complicated to pick up. At some point, I saw a function with called customer_greetcustomer_customer can I have the smallest idea, why would they have to make it this complicated, when they could easily and simply call it greetcustomer.

Anyways, I am stuck here: https://www.codecademy.com/courses/learn-python-3/lessons/intro-to-functions/exercises/returns

``````def calculate_age(current_year, birth_year):
age = current_year - birth_year
``````

I kinda get it, but I have no freaking idea what it is asking me to do with:

``````The function **calculate_age** in **script.py** creates a variable called **age** that is the difference between the current year, and a birth year, both of which are inputs of the function. Add a line to return **age**.
``````

What exactly it is asking me to do when saying Add a line to return age. Why cant they write it in a more simpler way to pick it up.

I would appreciate if someone, could explain what exactly are they saying with that, in a simpler way?

Hello @py6023654760, welcome to the forums! The code you currently have is correct, except you are missing the `return` statement. This basically just returns data to the program, and this allows you to store the data in variables, etc.
See below:

``````def a_function():
return 5
``````

You can now store this data in a variable:

``````some_var = a_function()
``````

The value of `some_var` is now 5, because that was the data `return`ed by the function.

I hope this helps!

Hello, thank you for the qucik answer.

Now it makes sense, I really could not get what it meant with “add a line…”.

So now, when I do this, it works.

``````def calculate_age(current_year, birth_year):
age = current_year - birth_year
return age
``````

Can’t believe it was that simple.
