Question

hi can you please solve this python problem for me??

Three pets live in a happy house: dog, cat and a mouse. The dog often chases the cat,
the cat likes to chase the mouse, however the mighty dog runs away when it sees the
mouse. Develop a game which can be played by two
players. The program asks the two players (player1 and player2) to choose either 1
for dog, 2 for cat, or 3 for mouse. The rules for this game are simple:
The dog prevails over the cat
The cat prevails over the mouse
The mouse prevails over the dog
So if player1 chooses a dog and player2 chooses a cat, player1 wins. If player1
chooses a dog and player2 chooses a mouse, player2 wins, and so forth. If both
players choose the same pet, then the result will be draw. The players continue
playing until either player hits enter without choosing a number (1, 2 or 3). Each time
the game is run, the result is printed on the screen (for example, Player 1 wins or
Player 2 wins).
Hint:
 Define an indefinite loop which only breaks when either player enters an
empty string (hits enter with no entry).
 Within the loop, prompt Player 1 and Player 2 to enter 1 for dog, 2 for cat or 3
for mouse
 Based on the choices made by Player 1 and Player 2, your program prints out
the appropriate message, which can either be “draw”, “Player 1 wins” or
“Player 2 wins”.
