Python_程序实现发红包

发红包

200块钱  20个红包

将200块随机分成20份　　

基础版本:

 import random

 ret = random.sample(range(1, 200 * 100), 19)
 ret =  ret.sort()
 ret.insert(0, 0)
 ret.append(200 * 100)
 l = []

 for  i in range(10):
 　　l.append((ret[i + 1] - ret[i]) / 100)

 print(l)

函数版本:

import random

def red_packet(money, num):
    ret = random.sample(range(1, money * 100), num - 1)
    ret =  ret.sort()
    ret.insert(0, 0)
    ret.append(money * 100)

    for  i in range(num):
　　    l.append((ret[i + 1] - ret[i]) / 100)

    return l

ret = red_packet(100, 10)
print(ret)

列表推导式版本:

import random

def red_packet(money, num):
    ret = random.sample(range(1, money * 100), num - 1)
    ret =  ret.sort()
    ret.insert(0, 0)
    ret.append(money * 100)

    return [(ret[i + 1] - ret[i]) / 100 for  i in range(num)]

ret = red_packet(100, 10)
print(ret)

进阶版:

 import random

 def red_packet(money, num):
     ret = random.sample(range(1, money * 100), num - 1)
     ret.extend([0, money * 100])  # 改进点
     ret =  ret.sort()

     return [(ret[i + 1] - ret[i])/100 for  i in range(num)]

 ret = red_packet(100, 10)
12 print(ret)

生成器版

 import random

 def red_packet(money, num):
     ret = random.sample(range(1, money * 100), num - 1)
     ret.extend([0, money * 100])
     ret.sort()

     for i in range(num):
         yield (ret[i + 1] - ret[i]) / 100

 red_packet(100, 10)
