IF/ELSE Control flow in Python to work out price of courier service from 4 choices

I cannot seem to understand how to use if/else in the following question:

● You need to design a program for a courier company to calculate the cost                         of sending a parcel. ● Ask the user to enter the price of the package they would like to purchase. ● Ask the user to enter the total distance of the delivery in kilometers. ● Now, add on the delivery costs to get the final cost of the product. There are                               four categories to factor in when determining a parcel’s final cost, each with                        two options based on the customer’s delivery preferences. (Use an if else                      statement based on the choice they make) ○ Delivery via air ($0.36 per km) or via freight ($0.25 per km) ○ Full insurance ($50.00) or limited insurance ($25.00) ○ Gift option ($15.00) or not ($0.00) ○ Priority delivery ($100.00) or standard delivery ($20.00) ● Write code to work out the total cost of the package based on the options                             selected in each category.

Can anyone help? Thank you.
