python--pygal

创建一个Die的类

from random import randint
import random
class Die():
    def __init__(self,num_sides=6):
        self.num_sides=num_sides
        
    def roll(self):
        return random.randint(1,self.num_sides)

将类进行实例化

from D6 import Die

die = Die()
results = []
for roll_num in range(100):
    result = die.roll()
    results.append(result)
    
#print(results)

frequencies = []
for value in range(1,die.num_sides+1):
    frequencie = results.count(value)
    frequencies.append(frequencie)
    
print(frequencies)

import pygal

hist = pygal.Bar()
hist.title = '一个色子投掷一百次的结果'
hist.x_labels =list('123456')
hist.x_title = '结果'
hist.y_title = '次数'

hist.add('D6',frequencies)

hist.render_to_file('D6_visual.svg')

实现列表可视化，保存为svg形式的文件

同时丢三个色子

from D6 import Die

die1 = Die()
die2 = Die()
die3 = Die()

results = []
for roll_num in range(100000):
    result = die1.roll() + die2.roll() + die3.roll()
    results.append(result)
    
frequencies = []
max_result = die1.num_sides + die2.num_sides +die3.num_sides
for value in range(3,max_result+1):
    frequencie = results.count(value)
    frequencies.append(frequencie)
    
import pygal

hist = pygal.Bar()
hist.title = '三个色子投掷十万次的结果'
hist.x_labels =list(range(3,19))
hist.x_title = '结果'
hist.y_title = '次数'

hist.add('D63',frequencies)

hist.render_to_file('D63_visual.svg')
