使用的是pygal函數庫 因此須要先安裝app
1 安裝庫文件dom
pip install pygal=1.7
2 建立骰子類ide
from random import randint class Die(): #表示一個骰子的類 def __init__(self, num_sides=6): #骰子默認爲6面 self.num_sides = num_sides def roll(self): #返回一個位於1和骰子面數之間的隨機數 return randint(1, self.num_sides)
3 2個不一樣面的骰子成的直方圖svg
import pygal from die import Die #建立1個D6和一個D10 die_1 = Die() die_2 = Die(10) #投擲幾回骰子,把結果存儲在列表中 results = [] for roll_num in range(50000): result=die_1.roll() + die_2.roll() results.append(result) #結果分析 frequencies = [] max_result = die_1.num_sides + die_2.num_sides for value in range(2, max_result): frequencie = results.count(value) frequencies.append(frequencie) #對結果進行可視化 hist = pygal.Bar() hist.title = "Results of rolling one D6 and one D10 50000 times" hist.x_labels = ['2','3','4','5','6','7','8','9','10','11','12','13','14','15','16'] hist.x_title = "Result" hist.y_title = "Frequency of Result" hist.add("D6 + D10", frequencies) hist.render_to_file('different_visual.svg')
