尝试模拟 2 个骰子以了解相同结果的百分比

Question

所以，我认为它们是代码中某处的逻辑错误。无论我在输出终端中插入任何数字，输出都保持运行 0%

#dice - count doubles in user - defined number of rounds.. repeated 
import random

#simulate rolling a six sided die and return its value. 
def rollOneDie():
    #generate random numbers from 1 to 6
    thisFace = random.randrange(1,7)
    return thisFace



while True:
    nDoubles = 0
    maxRounds = input(
        "how many rounds do you want to roll?(or ENTER to quit):")
    if maxRounds == '':
        break
    try:
        maxRounds = int(maxRounds)
    except:
        print("please an integer number")
        continue

    for roundNumbers in range(0, maxRounds):
        die1 = rollOneDie()
        die2 = rollOneDie()

    if die1 == die2:
        nDoubles = nDoubles + 1

    percent = (nDoubles * 100.0) / maxRounds
    print('out of ', maxRounds,  'you rolled',
      nDoubles, 'doubles or ', percent, '%')
print('ok byeee')

Answer 1

它打印 0% 的原因是检查骰子是否相同的 if 语句在“掷”骰子的 for 循环之外，所以只有当骰子相同时 nDoubles 才增加 1上次你“滚动”它们的时间。

正确的方法是：

for roundNumbers in range(0, maxRounds):
    die1 = rollOneDie()
    die2 = rollOneDie()

    if die1 == die2:
        nDoubles = nDoubles + 1

另外，你可以这样写：

nDoubles += 1

而不是

nDoubles = nDoubles + 1
