Python编程 从入门到实践 练习9-13、练习9-14_pythone 9-14

9-13 使用OrderedDict

# 打印编程词汇的含义
# 再添加5个python术语
from collections import OrderedDict

python_lists = OrderedDict()
python_lists['append'] = '将元素添加到列表末尾'
python_lists['insert'] = '可在列表的任何位置添加新元素'
python_lists['pop'] = '删除列表末尾的元素'


	
# 用循环遍历字典
for word, mean in python_lists.items():
	print(word + ":" + mean)

9-14 骰子

from random import randint

class Die():

	def __init__(self, sides = 6):
		self.sides = sides
	
	def roll_die(self):
		"""打印位于1和骰子面数之间的随机数"""
		x = randint(1, self.sides)
		print(x)

six_die = Die()
for number in range(1,11):
	six_die.roll_die()
ten_die = Die(10)
for number in range(1,11):
	ten_die.roll_die()
twenty_die = Die(20)
for number in range(1,11):
	twenty_die.roll_die()
