Thanks for the tip. I'll do that here and in future games.
In addition to using constants to parameterize the strings, the whole
game can be made simpler and easier to change when you realize that the
if/else block has a regular construction. Here's a sketch of one way to
take advantage of this structure (untested). You should be able to fill
in the elided code. Use lower case to check the input so a mistake in
capitalization doesn't reject the input. That's a simple courtesy to
the user.
import random #Allows for a random input.
ROCK = 'rock'
PAPER = 'paper'
SCISSORS = 'scissors'
TIE = 'Tie'
ULOSE = 'You Lose'
UWIN = 'You Win'
GAME = {
(ROCK, ROCK): TIE,
(ROCK, PAPER): ULOSE,
# ...
}
OPTIONS = (ROCK, PAPER, SCISSORS)
PROMPT = (f'Welcome to the {ROCK}, {PAPER}, {SCISSORS} game. ' +
'Choose one of the three')
# skipping some code
player_choice = input(PROMPT)
player_choice = player_choice.lower()
if player_choice not in OPTIONS:
print(f'{player_choice} is not an allowed input')
continue
result = GAME[(player_choice, choice)]
print(result)
# ...
