如何退出 while 循环 - 当 counterPosition >=100 开始新游戏时

Question

编写代码来模拟一个玩家的游戏，并计算完成游戏所需的掷骰子次数。应允许用户指定模拟的游戏数量，并且代码应计算每个游戏的平均掷骰子数。

import random
def diceRoll():
    return random.randint (1,6)
userInput = int(input("How many games would you like to play snakes and ladders?"))
totalDiceRolls = 0
for i in range(userInput):
counterPosition = 0
while (counterPosition < 100):
    totalDiceRolls += 1
    currentDiceRoll = diceRoll()
    counterPosition += currentDiceRoll
    if counterPosition == 1:
        counterPosition = counterPosition + 37
    if counterPosition == 4:
        counterPosition = counterPosition + 10
    if counterPosition == 9:
        counterPosition = counterPosition + 22
    if counterPosition == 21:
        counterPosition = counterPosition + 21
    if counterPosition == 28:
        counterPosition = counterPosition + 56
    if counterPosition == 51:
        counterPosition = counterPosition + 16
    if counterPosition == 72:
        counterPosition = counterPosition + 19
    if counterPosition == 80:
        counterPosition = counterPosition + 19
    if counterPosition == 17:
        counterPosition = counterPosition - 10
    if counterPosition == 54:
        counterPosition = counterPosition - 20
    if counterPosition == 63:
        counterPosition = counterPosition - 4
    if counterPosition == 64:
        counterPosition = counterPosition - 4
    if counterPosition == 87:
        counterPosition = counterPosition - 51
    if counterPosition == 92:
        counterPosition = counterPosition - 19
    if counterPosition == 95:
        counterPosition = counterPosition - 20
    if counterPosition == 98:
        counterPosition = counterPosition - 19
    if counterPosition >= 100:

avgRolls = totalDiceRolls / userInput
print("The average number of rolls per game is", avgRolls)

您更改了之前问题/答案的代码中的所有内容，现在它不起作用。

你在里面有循环while playGame():，但你while移到外面，但你没有移动其余的元素。

以前playGame():返回的掷骰子数，您可以将其添加到totalDiceRolls

totalDiceRolls += playGame()

但是现在playGame()返回None并且您会收到错误：

TypeError: unsupported operand type(s) for +=: 'int' and 'NoneType'

工作代码 - 无需playGame()

import random
def diceRoll():
    return random.randint (1,6)
userInput = int(input("How many games would you like to play snakes and ladders?"))
totalDiceRolls = 0
for i in range(userInput):
    counterPosition = 0 #setting counterposition and diceroll to 0
    while (counterPosition < 100):
        totalDiceRolls += 1
        currentDiceRoll = diceRoll()
        print("The currentDiceroll is", currentDiceRoll)
        counterPosition += currentDiceRoll
        if counterPosition == 1: #all the if statements show what happens if the one player lands on a snake or a ladder
            counterPosition = counterPosition + 37
        if counterPosition == 4:
            counterPosition = counterPosition + 10
        if counterPosition == 9:
            counterPosition = counterPosition + 22
        if counterPosition == 21:
            counterPosition = counterPosition + 21
        if counterPosition == 28:
            counterPosition = counterPosition + 56
        if counterPosition == 51:
            counterPosition = counterPosition + 16
        if counterPosition == 72:
            counterPosition = counterPosition + 19
        if counterPosition == 80:
            counterPosition = counterPosition + 19
        if counterPosition == 17:
            counterPosition = counterPosition - 10
        if counterPosition == 54:
            counterPosition = counterPosition - 20
        if counterPosition == 63:
            counterPosition = counterPosition - 4
        if counterPosition == 64:
            counterPosition = counterPosition - 4
        if counterPosition == 87:
            counterPosition = counterPosition - 51
        if counterPosition == 92:
            counterPosition = counterPosition - 19
        if counterPosition == 95:
            counterPosition = counterPosition - 20
        if counterPosition == 98:
            counterPosition = counterPosition - 19
        if counterPosition >= 100:
            print ("Congratulations end of game")
avgRolls = totalDiceRolls / userInput
print("The average number of rolls per game is", avgRolls)
