我正在尝试将“摇滚，纸，剪刀”作为我的第二个程序。我一直遇到错误，

"Traceback (most recent call last):
  File "/home/cabox/workspace/main.py", line 118, in <module>
  File "/home/cabox/workspace/main.py", line 48, in Rock_Paper_Scissors
    else:
NameError: name 'rps_choice' is not defined"

这是代码。

import time
import random

def Rock_Paper_Scissors():
  print("Welcome to the "Rock, Paper, Scissors" game!")

  time.sleep(2)

      if rps_choice.upper() == "ROCK":
        print("Great! You chose", rps_choice.upper(), end='')
        print("! The computer picked...")
        return rps_choice.upper()
      if rps_choice.upper() == "PAPER":
        print("Great! You chose", rps_choice.upper(), end='')

  print(rps_random, end='')

  time.sleep(2)

    rps_input()
  else:

        time.sleep(2)

        time.sleep(2)

      if rps_random == "PAPER":

        time.sleep(2)

        print("You WIN.")

  time.sleep(2)

  def RPS_Reset_Quit():
    rq = input("Restart or quit? (R/Q): ")
    if rq.lower() == "r":
      print("n")

    if rq.lower() == "q":
      print("Quiting...")

      time.sleep(2)

      quit()
    else:
      print("Sorry, please say either R or Q.")

      time.sleep(2)

      RPS_Reset_Quit()
  RPS_Reset_Quit()

Rock_Paper_Scissors()

正如您所看到的，我的变量 ,rps_choice没有定义，即使它是从rps_input()函数中定义和返回的。我真的不知道为什么会这样。

回答

rps_choice = rps_input()
