问题描述

我必须为我的比赛班制作这个游戏，我不知道如何打破这个循环.看，我必须与计算机"对战，滚动更大的数字，看看谁的分数更高.但我不知道如何从我的回合中断"，并过渡到计算机回合.我需要Q"(退出)来表示计算机开始转动，但我不知道该怎么做.

I have to make this game for my comp class, and I can't figure out how how break out of this loop. See, I have to play against the "computer," by rolling bigger numbers, and seeing who has the bigger score. But I can't figure out how to "break" from my turn, and transition to the computers turn. I need "Q" (quit) to signal the beginning of the computers turn, but I don't know how to do it.

ans=(R)
while True:
    print('Your score is so far '+str(myScore)+'.')
    print("Would you like to roll or quit?")
    ans=input("Roll...")
    if ans=='R':
        R=random.randint(1, 8)
        print("You rolled a "+str(R)+".")
        myScore=R+myScore
    if ans=='Q':
        print("Now I'll see if I can break your score...")
        break

推荐答案

一些变化意味着只有 R 或 r 会滚​​动.任何其他字符都会退出

A couple of changes mean that only an R or r will roll. Any other character will quit

import random

while True:
    print('Your score so far is {}.'.format(myScore))
    print("Would you like to roll or quit?")
    ans = input("Roll...")
    if ans.lower() == 'r':
        R = np.random.randint(1, 8)
        print("You rolled a {}.".format(R))
        myScore = R + myScore
    else:
        print("Now I'll see if I can break your score...")
        break
