Backstory (if you need one)

You're in charge of keeping track of the results of a foot race, but you didn't write down the finishers in any particular order, and your notes might also contain a few corrections. Write a program where you can enter your records, that will then print out the full results in order.

User interaction:

• Ask the user how many runners were in the race


• Based on how many runners there were, create a list that is exactly the right size to hold that many names
  
  


• Repeatedly ask the user
  
  




• Which place they would like to edit


• What the name of the runner who finished in that place is


• If they enter "-1" for the place to edit, they are done editing


• If the user wishes to edit a place they have already edited, just replace the previous name with the new name. No need to do anything special about this situation.
  
  




• Once they are finished editing, print out the results of the race




• See sample runs below for the required format


• If they never stated who finished in one of the places, state that this name is missing




• See section on "None" below
  
  






• You must write and use at least one function:
  
  
  
  
  • This extra function should handle printing the race results at the end. You'll need to pass in your list of runner names as a parameter. No return value is needed for this function.
    
    
    
    
    • You are certainly encouraged to decompose into more functions as you see opportunities, but that one is a requirement.
    
    
    
    
    
    
    • You should include a comment above each function explaining
    
    
    
    
    • What this function is used for
    
    
    • What information the user is expected to supply as parameters to the function
    
    
    • What the return value (if there is one) will mean to whoever called the function
    
    
    • You should include type hints for all function parameters and return types
      
      
    
    
    
    
    
    
  
  
  
  

"None"

• We showed a few examples of creating lists with the right capacity but no actual data stored yet. There's a special value built into Python named None (with no quotation marks) that we use to mark these blank spots.




• You can compare list positions to the value None using the is operator, like



if myList[i] is None:



• If this is giving you trouble, contact the professor or a Tutor Lab TA ASAP rather than trying to go it alone and getting frustrated.
  
  

Things you are not required to deal with:

• Assume that the user will not try to edit any non-existent places (so if they say there are 4 runners, they will not try to edit the 7th place runner)


Things you are required to handle


• Your list must be sized exactly right. If you just block off a list of size 1000 when there are only 5 runners, you'll lose points.


• For no extra credit but also no penalty, you can just put a "th" after each place number
  
  


• For up to 2 points extra credit, you must get number suffixes correct based on:




• Numbers ending in a '1' except numbers ending in '11' must have a suffix of "st", such as "1st"


• Numbers ending in a '2' except numbers ending in '12' must have a suffix of "nd", such as "2nd"


• Numbers ending in a '3' except numbers ending in '13' must have a suffix of "rd", such as "3rd"


• All other numbers will have a suffix of "th", such as "5th"
  
  




• 
  Plan this out before you start coding.
  
  
  
  • When you do start coding this up, tackle it one little piece at a time, and test as you go.
  
  
  
  
  • Perhaps just start by asking the user what place to edit and what the name is until they enter -1 (not bothering to actually store anything yet).
  
  
  • Once you have that part working properly, add in actually storing the names and repeating the runner names back to the user at the end.
  
  
  • Once you have that working, add in getting the number suffixes correct, detecting missing runners, etc.

  Basic Point Breakdown:

  
  




• 
  

  4pts: Collecting number of runners and allocating a blank list of correct size
  5pts: Correctly looping during input and storing names using correct index
  2pt: Stop editing when user enters "-1"
  5pts: Output race results in order as a separate method
  2pt: State that a racer is missing (rather than just printing "None")
  2pt: formatting, coding style, comments
  2pt extra credit: Number suffixes
