Question

Need help writing this code in python.

Chapter 4: Use functions to organize the program Update the program so it uses functions to organize the code so it's easier to reuse and maintain. Console Baseball Team Mana MENU OPTIONS 1 - Calculate batting average 2 - Exit program Menu option: 1 Calculate batting average. . . Official number f at bats : 10 Number of hits: 3 Batting average: 0.3 Menu option: 1 Calculate batting average.. . Official number of at bats: 11 Number of hits 4 Batting average: 0.364 Menu option: 3 Not a valid option. Please try again MENU OPTIONS 1 - Calculate batting average 2 - Exit program Menu option:2 Bye! Specifications Use a function to store the code that displays the menu. . Use a function to store the code that calculates the batting average . Use a main function to store the rest of the code Assume the user will enter valid data. f the user enters an invalid menu option, display an error message and display the menu again, so the user can clearly see the valid menu options.

This what I have so far.

def display_menu():
print("======================================================================")
print(" Baseball Team Manager")
print("MENU OPTIONS")
print("1 - Calculate batting average")
print("2 - Exit program")
print("=====================================================================")
  

def convert_bat():
option = int(input("Menu option: "))
while option!=2:
if option ==1:
print("Calculate batting average...")
num_at_bats = int(input("Enter official number of at bats: "))
num_hits = int(input("Enter number of hits: "))
average = num_hits/num_at_bats
print("batting average: ", average)
elif option !=1 and option !=2:
print("Not a valid option. Please try again.")
convert_bat()
def main():
display_menu()
convert_bat()
convert_bat()
  
main()

Answer 1

Screenshot of the code:

#Function to store the code that displays the menu. def display_menu(): # The Display menu. p r int ("====================================================================== ") print(" Baseball Team Manager") print ("MENU OPTIONS") print("1 - Calculate batting average") print ("2 - Exit program") print("=====================================================================") #Function to store the code that calculates the batting average. def convert bat(): #Print the required statement. print("Calculate batting average...") #Prompt the user to enter the number of at bats. num_at_bats = int (input ("Enter official number of at bats: ")) #Prompt the user to enter the number of hits num_hits = int(input ("Enter number of hits: ")) #Calculate the average. average = num_hits/num_at_bats #Print the average. print ("Batting average: %.3f" % average)

#The main function to store the rest of the code. def main(): #The menu is displayed again. while True: #First the menu is displayed. display_menu () #Prompt the user to enter the option 1 or 2. ch = int(input ("Menu Option : ")) #If option is 1, call the function convert bat () if (ch == 1): convert_bat () #If the option is 2, print Bye and exit the function. elif (ch == 2): print ("Bye !") break else: #Error message is displayed if the user enters an invalid menu option. print ("Not a valid option. Please try again.") main()

Sample Output:

= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = Baseball Team Manager MENU OPTIONS 1 - Calculate batting average 2 - Exit program ===================================================================== Menu Option : 1 Calculate batting average... Enter official number of at bats: 10 Enter number of hits: 3 Batting average: 0.300 ========== ============ =========== =========== =========== =========== ==== Baseball Team Manager MENU OPTIONS 1 - Calculate batting average 2 - Exit program ===================================================================== Menu Option : 1 Calculate batting average...
