機器學習之擲骰子的Python程式

首先用pip 工具安裝子產品pygal

import pygal

from random import randint

class Die():

def init(self,num_sides=6):

self.num_sides=num_sides

def roll(self):

return randint(1,self.num_sides)

die_1=Die()

die_2=Die(10)

results=[]

for roll_num in range(50000):

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

results.append(result)

print(results)

frequencies=[]

max_results=die_1.num_sides+die_2.num_sides

for value in range(2,max_results+1):

frequency=results.count(value)

frequencies.append(frequency)

print(frequencies)

hist=pygal.Bar()

hist.title=‘results of rolling two D6 dices 1000 times.’

hist.xlabels=[‘1’,‘2’,‘3’,‘4’,‘5’,‘6’,‘7’, ‘8’, ‘9’, ‘10’, ‘11’, ‘12’,‘13’, ‘14’, ‘15’, ‘16’]

hist.x_title=‘results’

hist.y_title=‘frequency of result’

hist.add(‘D6+D10’,frequencies)

hist.render_to_file(‘dice_visual.svg’)
