+# create a rock paper scissors game
+# The rock, paper, scissors game is a hand game in which each player chooses one of the three tools and these will be compared to see who wins.
+# The winner of the game is based in three simple rules: #
+# Rock wins against scissors.
+# Scissors win against paper.
+# Paper wins against rock.
+# If both players choose the same tool, the game ends in a tie.
+# The game will be implemented in the following way:
+# The computer will randomly choose one of the three tools.
+# The user will enter their name.
+# The user will choose one of the three tools.
+# A message indicating who won the game will be displayed.
+# The game will be implemented using the following steps:
+# Import the random module.
+# Define a list of the three tools: rock, paper, and scissors.
+# Define a variable that will store the name of the user.
+# Define a variable that will store the name of the computer.
+# Define a variable that will store the tool chosen by the user.
+# Define a variable that will store the tool chosen by the computer.
+# Define a variable that will store the result of the game.
+# Define a function that will print the message indicating who won the game.
+# The player can choose one of the three options rock, paper, or scissors and should be warned if they enter an invalid option.
+#At each round, the player must enter one of the options in the list and be informed if they won, lost, or tied with the opponent.
+#By the end of each round, the player can choose whether to play again.
+#Display the player's score at the end of the game.
+#The minigame must handle user inputs, putting them in lowercase and informing the user if the option is invalid.
