使用pygal模拟掷骰子

• pygal的安装
  • 　　通过pycharm 直接安装
  • Die class

    from random import randint
    
    
    class Die:
        """表示一个骰子的类"""
    
        def __init__(self, num_sides=6):
            self.num_sides = num_sides
    
        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)
    

    　　

  • 代码如下：

    import pygal
    from die import Die
    
    count = 50000
    die1Count = 6
    die2Count = 6
    die1 = Die(die1Count)
    die2 = Die(die2Count)
    results = []
    for roll_num in range(count):
        result = die1.roll() + die2.roll()
        results.append(result)
    
    frequencies = []
    max_result = die1.num_sides + die2.num_sides
    for value in range(2, max_result+1):
        frequency = results.count(value)
        frequencies.append(frequency)
    
    # 可视化结果
    hist = pygal.Bar()
    
    hist.title = "Result of rolling  D"+str(die1Count) + " + D"+str(die2Count)+" dice "+str(count)+" times"
    labels =[]
    for l in range(2, max_result+1):
        labels.append(str(l))
    hist.x_labels = labels
    hist.x_title = "Result"
    hist.y_title = "Frequency of Result"
    hist.add('D'+str(die1Count) + '+ D'+str(die2Count), frequencies)
    hist.render_to_file('dice_visual'+str(count)+'.svg')
