题目 模拟投掷两颗色子1000次，统计两颗色子点数，用柱状图表示他们的分布, 代码如下： from random import randint import pygal class Die ( ) : def __init__ ( self , num_sides = 6 ) : self . num_sides = num_sides def roll ( self ) : return randint ( 1 , self . num_sides ) die1 = Die ( ) die2 = Die ( ) results = [ ] frequencies = [ ] for roll_num in range ( 1000 ) : result = die1 . roll ( ) + die2 . roll ( ) results . append ( result ) for value in range ( 2 , die1 . num_sides + die2 . num_sides + 1 ) : frequency = results . count ( value ) frequencies . append ( frequency ) hist = pygal . Bar ( ) hist . title = 'result of rolling two
