It's my first time here and I'm kinda panicking. I have an assignment to code Rock, Paper, Scissors in Python. (I use Python 3.1) and for some reason the function is not running...?
Here's the code:
hscore = 0
cscore = 0
tries = 0
#computer choice
rock = ("rock")
paper = ("paper")
scissors = ("scissors")
rps = (rock, paper, scissors)
cchoice = random.choice(rps)
choice = input("\nWhat do you choose? <rock, paper, scissors>: ")
tries +=1
def humanfunction():
if choice == "rock":
if cchoice == scissors:
print("Human wins this round.")
hscore +=1
if choice == "scissors":
if cchoice == paper:
print("Human wins this round.")
hscore +=1
if choice == "paper":
if cchoice == rock:
print("Human wins this round.")
hscore +=1
if cchoice == choice:
print("Tie.")
def compfunction():
if cchoice == scissors:
if choice == "paper":
print("Computer wins this round.")
cscore +=1
if cchoice == rock:
if choice == "scissors":
print("Computer wins this round.")
cscore +=1
if cchoice == paper:
if choice == "rock":
print("Computer wins this rounud.")
cscore +=1
if cchoice == choice:
print("Tie.")
def choose():
tries = 0
while 0 == 0:
choice = input("\nWhat do you choose? <rock, paper, scissors>: ")
tries +=1
print("\nHuman choice: ", choice)
print("Computer choice: ", cchoice)
print("Finished game number", tries)
if tries == 10:
print("Limit reached!")
break
humanfunction()
compfunction()
choose()
I've been trying to solve this for days now and for some reason, when I run the code, it doesn't show up who won. Help would be appreciated <3
EDIT: here's what i get when i run the code: output
the program is actually supposed to show this: output2

Here is my take on your code.
The main reason it wasn't running is that your cscore
variable was being referenced before it was initialized, because you had setup cscore
as a global
variable, but didn't declare it as a global
variable in your function.
You also needed to import the random
library
Also instead of doing 4 if/then
statements I combined them into 1 if/then
statement
EDIT: cleaned up the code a little more
EDIT 2: no more globals, avoid globals if possible
import random
def get_human_choice():
valid_choice = False
while not valid_choice:
choice = input("\nWhat do you choose? <rock, paper, scissors>: ")
if choice == 'rock' or 'paper' or 'scissors':
valid_choice = True
return choice
def get_comp_choice():
rps = ('rock', 'paper', 'scissors')
comp_choice = random.choice(rps)
return comp_choice
def human_winner(comp_choice):
print("The computer chooses: %s" % comp_choice)
print("Human wins this round.")
def comp_winner(comp_choice):
print("The computer chooses: %s" % comp_choice)
print("Computer wins this round.")
def stats(attempts, human_score, comp_scored, tie_score):
print("Finished game number: %s" % attempts)
print('Human Score: %s' % human_score)
print('Computer Score: %s' % comp_scored)
print('Ties: %s' % tie_score)
def play_game(human_score, comp_score, tie_score):
choice = get_human_choice()
comp_choice = get_comp_choice()
if choice == 'rock':
if comp_choice == 'scissors':
human_winner(comp_choice)
human_score += 1
else:
comp_winner(comp_choice)
comp_score += 1
elif choice == 'scissors':
if comp_choice == 'paper':
human_winner(comp_choice)
human_score += 1
else:
comp_winner(comp_choice)
comp_score += 1
elif choice == 'paper':
if comp_choice == 'rock':
human_winner(comp_choice)
human_score += 1
else:
comp_winner(comp_choice)
comp_score += 1
elif choice == comp_choice:
print("Tie.")
tie_score += 1
return human_score, comp_score, tie_score
if __name__ == '__main__':
tries = 1
h_score, c_score, t_score = 0, 0, 0
while tries <= 10:
h_score, c_score, t_score = play_game(h_score, c_score, t_score)
if tries == 10:
print("\nLimit reached!\n")
stats(tries, h_score, c_score, t_score)
break
else:
tries += 1
