学习python：练习5.简单红包程序
# 简单的拼手气红包import random
from time import sleep
# 所有涉及金额的浮点数都需要用 round 方法保留2位小数，避免出现最终结果多出0.01
amount = round(float(input('请设置红包的金额 \> ')),2)
num = int(input('请设置红包的数量 \> '))
hb_dict = {}
xing = '赵钱孙李周吴郑王'
ming = '一二三四五六七八九十'
while num:
xingming = random.choice(xing)+random.choice(ming)+random.choice(ming)
if xingming in hb_dict.keys():
xingming = random.choice(xing)+random.choice(ming)+random.choice(ming)
num -= 1
if num == 0:
print('%s抢到红包%.2f元 红包抢完了!' % (xingming,amount))
hb_dict = xingming
amount -= amount
elif num > 0:
hb = round(random.uniform(0.01,amount)/num,2)
hb_dict = xingming
# 算法: 在0.01到红包总金额之间随机一个浮点数 / 红包剩余个数
print('%s抢到红包%.2f元 剩余%d个!' % (xingming,hb,num))
amount = round((amount - hb),2)
sleep(1)
# 转置字典中的 key / value
# hb_dict2 = {value:key for key,value in hb_dict.items()}
max_hb = max(hb_dict.items())
print('%s运气最佳 抢得%.2f元!!' % (max_hb,max_hb))
