issue with if else statement

[spalisetty06]

Hello,
I have tried to program something simple as I am a beginner. But it always executes else part, I don't know why. Please correct my code.

import random
Player1 = ["Rock", "Paper", "Scissor"]
Player2 = ["Rock", "Paper", "Scissor"]
Player1 = random.choice(Player1)
Player2 = random.choice(Player2)
print("Player1 and Player2 are ",Player1, Player2)
choice = input("Please select your choice by entering Y or N ")
while choice!='N':
    if Player1 == "Rock" and Player2 == "Paper":
        print("Player2 is the winner")
        choice = input("Please select your choice by entering Y or N ")
    elif Player1 == "Rock" and Player2 == "Scissor":
        print("Player1 is the winner")
        choice = input("Please select your choice by entering Y or N ")
    else:
        print("No loser")
        choice = input("Please select your choice by entering Y or N ")
