One practice I follow is declaring strings, _especially_ those used more
than once, at the top:
import random #Allows for a random input.
ROCK = "Rock" # Defined once
PAPER = "Paper" # Defined once
SCISSORS = "Scissors" # Defined once
options = [ROCK, PAPER, SCISSORS] #Tells the computer what its options are.
playerchoices = []
repeat = True
while repeat == True:
rand_choice = random.randint(1,3)
choice = options[rand_choice-1] #defines player options and selection
while True:
player_choice = input("Welcome to Rock, Paper, Scissors. To begin,
choose Rock, Paper, or Scissors. ")
if player_choice == ROCK:
break
if player_choice == PAPER:
break
if player_choice == SCISSORS:
...
The advantage of this approach is misspellings generate compilation errors,
which are easier to catch and fix.
