greetings Niclas, and welcome to Python! while i'll let the others comment
on your code specifically, i can give some overall suggestions/guidance.

you're trying to create an overall price calculator correct? while it's
straightforward providing a base price, the complexity in your app (and
real life) is the set of options that customers can choose from.

in your situation, i think it would be more "Pythonic" to maintain the
extras as a vector of options and prices. you then loop through those,
prompting the user to enter Yes or No, and add either the cost or zero,
respectively. that will help keep your code less complex as well. you would
just be maintaining a running total until the user is done with all their
selections.

good luck!
