Question

写下2个六面骰子的滚动模拟。你的程序应该有一个Roll（）函数，它返回掷骰子的总和。你可以假设六个方面中的每一个都同样可能被滚动（也就是说，骰子是“公平的”）。运行模拟1000次并报告每次总和发生的频率。

到目前为止我有这个，但我的程序似乎不会加总。我可能完全错了。请帮忙。我认为我的主要问题在于我的印刷声明。我需要输出打印2次显示总和的次数，3的总和，4的总和，直到12。

def Roll():
    for i in range(1000):
        one = 0
        two = 0
        three = 0
        four = 0
        five = 0
        six = 0
        dice1= float(0)
        dice2= float(0)

        dice1 = random.randint(1,6)
        if dice1 == 1:    
            one = one + 1
            count= 1
            return count
        elif dice1 == 2:
            two = two + 1
            count= 1
            return count
        elif dice1 == 3:
            three = three + 1
            count= 1
            return count
        elif dice1 == 4:
            four = four + 1
            count= 1
            return count
        elif dice1 == 5:
            five = five + 1
            count= 1
            return count
        else:
            six = six + 1
            count= 1
            return count

        dice2 = random.randint(1,6)
        if dice2 == 1:    
            one = one + 1
        elif dice2 == 2:
            two = two + 1
        elif dice2 == 3:
            three = three + 1
        elif dice2 == 4:
            four = four + 1
        elif dice2 == 5:
            five = five + 1
        else:
            six = six + 1

        total = one + two + three + four + five + six

        print("2", dice1 + dice2)   
        print("3", dice1 + dice2)
        print("4", dice1 + dice2)
        print("5", dice1 + dice2)
        print("6", dice1 + dice2)    
        print("7", dice1 + dice2)
        print("8", dice1 + dice2)   
        print("9", dice1 + dice2)
        print("10", dice1 + dice2)
        print("11", dice1 + dice2)
        print("12", dice1 + dice2)

我已经回答了你的一位朋友，他的任务相同：

import random
from collections import defaultdict

def main():
    dice = int(input("Enter the number of dice: "))
    sides = int(input("Enter the number of sides: "))
    rolls = int(input("Enter the number of rolls to simulate: "))
    result = roll(dice, sides, rolls)
    maxH = 0
    for i in range(dice, dice * sides + 1):
        if result[i] / rolls > maxH: maxH = result[i] / rolls
    for i in range(dice, dice * sides + 1):
        print('{:2d}{:10d}{:8.2%} {}'.format(i, result[i], result[i] / rolls, '#' * int(result[i] / rolls / maxH * 40)))


def roll(dice, sides, rolls):
    d = defaultdict(int)
    for _ in range(rolls):
        d[sum(random.randint(1, sides) for _ in range(dice))] += 1
    return d

main()

您可以取出对您有用的部分。这还应该包括后续问题，例如：“我如何整齐地打印”和“如何绘制直方图”。

示例：

Enter the number of dice: 2
Enter the number of sides: 6
Enter the number of rolls to simulate: 1000
 2        28   2.80% ######
 3        59   5.90% #############
 4        84   8.40% ###################
 5        96   9.60% ######################
 6       155  15.50% ####################################
 7       170  17.00% ########################################
 8       147  14.70% ##################################
 9       102  10.20% #######################
10        80   8.00% ##################
11        50   5.00% ###########
12        29   2.90% ######

Answer 2

这是一个快速而肮脏的方法

from collections import Counter
import random

def roll():
  return random.randint(1,6) + random.randint(1,6)

counter = Counter( roll() for _ in range(1000) )

for num, cnt in counter.iteritems():
  print '%2d: %.3f' % (num, cnt / 1000.0)

导致

 2: 0.022
 3: 0.063
 4: 0.072
 5: 0.104
 6: 0.154
 7: 0.174
 8: 0.141
 9: 0.112
10: 0.077
11: 0.057
12: 0.024
