15-6 自动生成标签 自动生成标签 ：请修改die.py和dice_visual.py，将用来设置hist.x_labels 值的列表替换为一个自动生成这种列表的循环。如果你熟悉列表解析，可尝试将 die_visual.py和dice_visual.py中的其他for 循环也替换为列表解析。 

die.py

from randomimport randint

class Die():

#标识一个骰子的类

    def __init__(self,num_sides=6,num_sidess =12):

#骰子迷人为六面

        self.num_sides = num_sides

self.num_sidess = num_sidess

def roll(self):

#返回一个位于1和骰子面数之间的随机值

        return randint(1,self.num_sides)

def rolll(self):

#返回一个位于1和12之间的随机值

        return  randint(1,self.num_sidess)

die_visual.py

from dieimport Die

import pygal

#创建一个D6

die_1 = Die()

die_2 = Die()

results = []

for roll_numin range(10000):

result = die_1.roll()+die_2.rolll()

results.append(result)

print(results)

#分析结果

frequencies=[]

max_result = die_1.num_sides + die_2.num_sidess

for valuein range(2,max_result):

frequenciey = results.count(value)

frequencies.append(frequenciey)

print(frequencies)

#对结果可视化

hist = pygal.Bar()

hist.title ="Results of rolling one D6 1000 times."

hist.x_labels = []

for aaain range(2,19):

apws = aaa

hist.x_labels.append(apws)

hist.x_title ="Resultaaaa"

hist.y_title ="Frequency of Resultbbbb"

hist.add('D6666',frequencies)

hist.render_to_file('die_visual.svg')

15-7 两个 两个D8骰子： 骰子： 请模拟同时掷两个8面骰子1000次的结果。逐渐增加掷骰子的次数，直到系统不堪重负为止。 

die.py不用改变。

die_visual.py

from dieimport Die

import pygal

#创建一个D6

die_1 = Die(8)

die_2 = Die(8)

results = []

for roll_numin range(10000):

result = die_1.roll()+die_2.roll()

results.append(result)

print(results)

#分析结果

frequencies=[]

max_result = die_1.num_sides + die_2.num_sides

for valuein range(2,max_result+1):

frequenciey = results.count(value)

frequencies.append(frequenciey)

print(frequencies)

#对结果可视化

hist = pygal.Bar()

hist.title ="Results of rolling one D6 1000 times."

hist.x_labels = []

for aaain range(2,17):

apws = aaa

hist.x_labels.append(apws)

hist.x_title ="Resultaaaa"

hist.y_title ="Frequency of Resultbbbb"

hist.add('D6666',frequencies)

hist.render_to_file('die_visual.svg')
