    <p>I am trying to write a Python program and I am having a hard time getting my score. I have written it as a value returning function and every time I run the program it seems to skip the step where it retrieves the score unless I include an else statement which it will automatcially jump the the else statement. I will attach the full code below. Thank you very much for any help, I'm greatful! This is also my first time posting in this forum I apologize if I screw something up. </p> <pre><code>#constants Rock = 1 Paper = 2 Scissors = 3 #Define the main function def main(): #set control loop keep_going = 'Y' #set counter to zero computer_wins = 0 player_wins = 0 tie_score = 0 #call display message display_message() while keep_going == 'y' or keep_going == 'Y': play_game() #prompt user to keep going keep_going = input('would you like to play again? (Y for Yes): ') print('The computer won', computer_wins, 'times') print('The player won', player_wins, 'times') print('There were', tie_score, 'tie scores') def play_game(): #get random input computer = get_random() #get the players input play = get_play() #validate input if play == '1' or play == '2' or play == '3': play == True else: play == False print('Error: Invalid Entry') play = input('Please enter 1 for Rock, 2 for Paper, or 3 for Scissors: ') if play == computer: print('Tie Score, Please try again') tie_score += 1 else: get_score(computer, play) print('The computer chose:', computer) print('The player chose: ', play) #define display message def display_message(): print('Welcome to Rock Paper Scissors, a game of chance to see who will') print('outsmart the other. This game is Man VS Computer.') print('The program will select a random integer and then ask you for an integer') print('1 for Rock 2 for paper or 3 for Scissors. The program will then tell') print('you who won the game.') print('GOOD LUCK!') print print def get_random(): import random #generate random int computer = random.randint(1, 3) return computer def get_play(): #prompt user to enter an integer 1, 2, or 3 play = input('Select 1 for Rock, 2 for Paper, or 3 for Scissors: ') return play def get_score(computer, play): if computer == 1 and play == 2: score = 'player wins' print('Paper covers Rock, Player Wins') #player wins player_wins += 1 elif computer == 1 and play == 3: score = 'computer wins' print('Scissors cut Paper, Computer Wins') #computer wins computer_wins += 1 elif computer == 2 and play == 1: score = 'computer wins' print('Paper covers Rock, Computer Wins') #computer wins computer_wins += 1 elif computer == 2 and play == 3: score = 'player wins' print('Scissors cut Paper, Player Wins') #player wins player_wins += 1 elif computer == 3 and play == 1: score = 'player wins' print('Rock smashes Scissors, Player Wins') #player wins player_wins += 1 elif computer == 3 and play == 2: score = 'computer wins' print('Scissors cut Paper, Computer Wins') #computer wins computer_wins += 1 #call main function main() </code></pre>

    2. COWhat do you mean by "value returning function"? The `get_score` function doesn't return anything.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
