練習使用本章介紹的兩個庫：嘗試使用matplotlib通過視覺化來模擬擲骰子的情況，並嘗試使用Pygal通過視覺化來模擬隨機漫步的情況

下面僅列出相關程式，匯入的類為書中所寫的類

from die import Die
import matplotlib.pyplot as plt 
import matplotlib.patches as mpatches


die_1 = Die()
die_2 = Die(10)

results = []
for roll_num in range(50000):
    #result = die_1.roll()
    result = die_1.roll() + die_2.roll()
    results.append(result)

frequencies =[]
#max_results = die_1.num_sides 
max_results = die_1.num_sides + die_2.num_sides
X_Range = list(set(results))
for value in X_Range:
    frequency = results.count(value)
    frequencies.append(frequency)

plt.bar(X_Range,frequencies,color = 'Pink',align='center',label = 'D6+D6')
plt.xticks(X_Range)


plt.xlabel("Results",fontsize = 8)
plt.ylabel("Frequencies", fontsize = 8)

#圖例
pink_patch = mpatches.Patch(color='Pink', label='D6+D6')
plt.legend(handles=[pink_patch])

plt.show()

 

用Pygal實現隨機漫步的程式為：

import pygal
from random_walk import RandomWalk

rw = RandomWalk(1000)
rw.fill_walk()

xy_chart = pygal.XY(stroke = False)  #stroke=False散點不連線
xy_chart.title = 'RandomWalk'
pygal.Line(include_x_axis = False,include_y_axis = False)

#把生成的值變成座標
xy_list = []
for (x,y) in zip(rw.x_values,rw.y_values):
    xy_list.append((x,y))

xy_chart.add('data', xy_list)

xy_chart.render_to_file('RandomWalk.svg')
 

相信解法多種多樣，看完了基礎的就直接學後面的了，其中pygal想換顏色和隱藏座標軸還沒實現，如有大神知道，希望能告知~拜謝！
