Hi,


I am just start learning Python and I have an activity to do
RockPaperScissors game using dictionary. I have written my code and it
doesn't work at all. I am sending my code and the
requirements. Can you please have a look and point out what is wrong there.
Thank you very much.

Warm regards,
Pau

program requirements:

 The program will display an appropriate welcome message and user
instructions.

 The program must use a Python dictionary to hold data shown in the table
below:

Game Command              Value

R                                             Rock

P                                             Paper

S                                              Scissors

E                                              Exit

 The player will enter their choice of shape by entering a valid Game
Command.

 Any invalid input must generate an exception that is handled and used to
display an appropriate error message.

 For correct inputs, the computer will randomly pick a dictionary item
(other than ‘Exit’) and compare that value with the user’s, before
returning the game result.

 For the game result the program must return details of the following:

o The user’s selection

o The computer’s selection

o The winning hand

o A running total of user wins including this game and previous games

 The program will repeat the game until the user exits by entering ‘e’.

# RockPaperScissors

print ("Hello.. Welcome from Rock, Paper, Scissors Game!!\n"
       +"Game instruction:\n"
       +"You will be playing with the computer.\n"
       +"You need to choose one of your choice: Rock, Paper or Scissors.\n"
       +"Enter 'e' to exit the game.\n")
