Stuck on this for ages. Please could really use help! Code is made using python

Create a program using Python IDLE or VS Code that allows you to build a burger. The program needs to ask the user how many patties the burger will have. The cost of a single patty is $5.50, a double is $6.50 and triple patty is $7.50. Additionally you will want to ask the user if they want cheese, which will cost $1 more. Burgers come with lettuce, pickles and onions. The program will also need to ask the user how many burgers they wish to build. Finally the program needs to print out the cost of one burger and then the total. When putting together this program, remember to start with your decomposition. What does the program need to do? What are the steps? Additionally figure out what the inputs and outputs are. When run the program's output should look like the following: Enter how many patties (single, double, triple): double Do you want cheese on your burger? (yes or no): yes How many burgers do you wish to purchase: 3 The cost for one burger is: $ 7.5 The total cost for all of your burgers is: 22.5
