Question

In this project, you will use functions and dictionaries to track basketball players and their respective points, then display statistics of points made.

You will need three functions as follows:

• def freeThrowMade(playerDictionary, playerName) - this function will add 1 point to the player's total score
• def twoPointMade(playerDictionary, playerName) - this function will add 2 points to the player's total score
• def threePointMade(playerDictionary, playerName) - this function will add 3 points to the player's total score

Each of these functions has two parameters, a dictionary and a string, and will return the dictionary.

You program should have a menu as follows:

• (1) Add Free Throw
• (2) Add Two Pointer
• (3) Add Three Pointer
• (4) Display Statistics
• (5) Exit

You should display the following when the user chooses statistics:

• Each player and their respective score
• Number of players
• Total of all scores
• Average score per player

You should create a rough-sketch of the flow of this program, before you start coding. Consider the following:

• Display the menu
• Prompt the user for the menu choice
• If adding points throw
  • prompt the user for the player name and then call the appropriate function
• else if displaying statistics
  • show the total, average, max, and min scores
• else if exit the program
  • display exit message
• else display error message

You should also create a rough-sketch of each function before you start coding. Consider the following for the free throw function:

• Determine if the player is already in the dictionary (hint: consider the get() function)
• If the player is in the dictionary
  • update their score. Get the current score, determine the new score, and update the dictionary
• else
  • add the player and score to the dictionary

Your program should continue to prompt the user until menu choice 5 is entered. If the user enters an invalid menu choice, display Invalid menu choice

Code as text:

# this function will add 1 point to players total score

def freeThrowMade(playerDictionary, playerName):

if playerDictionary.get(playerName) == None:

playerDictionary[playerName] = 1

else:

playerDictionary[playerName] += 1

return playerDictionary

# this function will add 2 points to players total score

def twoPointMade(playerDictionary, playerName):

if playerDictionary.get(playerName) == None:

playerDictionary[playerName] = 2

else:

return playerDictionary

# this function will add 3 points to players total score

def threePointMade(playerDictionary, playerName):

if playerDictionary.get(playerName) == None:

else:

return playerDictionary

# main driver

def main():

# display menu

print("****Menu****")

while True:

freeThrowMade(playerDictionary, playerName)

elif choice == 2: #add 2 points

twoPointMade(playerDictionary, playerName)

elif choice == 3: #add 3 points

playerName = input("Enter player name: ")

threePointMade(playerDictionary, playerName)

elif choice == 4: #display statistics

playerCount = 0

totalScore = 0

print("\n****Displaying Statistics****\n")

# print each player name and score

for name in playerDictionary:

print("%10s %3d" %(name, playerDictionary[name]))

playerCount += 1

totalScore += playerDictionary[name]

print("Number of players: ", playerCount)

print("Total of all scores: ", totalScore)

print("Average score per player: %.2f" % (totalScore/playerCount))

elif choice == 5: # exit

print("Exiting!!")

break

else: # invalid choice

print("Invalid menu choice.")
