Day 30 - Enhanced Rock, Paper, Scissors with Custom Functions

We will begin with the code from Day 15 - the basic Rock, Paper, Scissors game. We will make it more playable, and re-playable using loops and custom functions.

Starter Code

import random

print("~"*60)
print("Rock, Paper Scissors!".center(60))
print("~"*60)
print("\n")

# Computer's Guess
liChoices = ["r","p","s"]
strCC = random.choice(liChoices)

# User-friendly version
if (strCC == "r"):
    strCCp = "rock"
elif (strCC == "p"):
    strCCp = "paper"
else:
    strCCp = "scissors"

# User's Choice
while True:
    strUC = input("Choose (r)ock, (p)aper, or (s)cissors: ").lower()

    if (strUC == "r" or strUC == "rock"):
        strUC = "r"
        strUCp = "rock"
        break

        break
    else:
        print("\nThat isn't a valid choice.\nEnter r, p or s.\n")

print(f"You entered {strUCp}")
print(f"The computer chose {strCCp}")

if (strCC == strUC):
    print("It's a TIE!")
else:
    if strUC == "r":

        else:
