STEP 5: Let's use the function parameter variable in our function! We can pass in party theme information!

• Change the parameter variable name from my_var to theme.
• Change the string in .set_background() to the variable theme.

We now have a function using one parameter. Every time we call this function, we must provide an argument for the parameter! If we don't, we will get a syntax error. Click Next to call draw_card() with a custom value!
