本文介绍了一个使用Python实现的随机数生成器，它能够模拟不同面数的骰子投掷。代码中定义了一个名为Die的类，通过实例化这个类可以创建任意面数的骰子，并进行多次投掷实验，展示随机数的分布情况。

from random import randint

class Die():
	def __init__(self,sides=6):
		# initialize the die.
		self.sides = sides

	def roll_die(self):
		# return a number between 1 and the number of sides.
		return randint(1,self.sides)

d6 = Die()

results = []
for roll_num in range(10):
	result = d6.roll_die()
	results.append(result)
print("10 rolls of a 6-sided die: ")
print(results)

d10 = Die(sides=10)

results = []
for roll_num in range(10):
	result = d10.roll_die()
	results.append(result)
print("\n10 rolls of a 10-sided die: ")
print(results)

d20 = Die(sides=20)

results = []
for roll_num in range(10):
	result = d20.roll_die()
	results.append(result)
print("\n10 rolls of a 20-sided die: ")
print(results)
