200塊錢  20個紅包

將200塊隨機分成20份　　

基礎版本:

 1 import random 2  3  4 ret = random.sample(range(1, 200 * 100), 19) 5 ret =  ret.sort() 6 ret.insert(0, 0) 7 ret.append(200 * 100) 8 l = [] 9 10 for  i in range(10):11 　　l.append((ret[i + 1] - ret[i]) / 100)12 13 print(l)

 

 

函數版本:

import randomdef 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 lret = red_packet(100, 10)
print(ret)

 

 列表推導式版本:

import randomdef 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)

 

 

進階版:

 1 import random 2  3  4 def red_packet(money, num): 5     ret = random.sample(range(1, money * 100), num - 1) 6     ret.extend([0, money * 100])  # 改進點 7     ret =  ret.sort() 8  9     return [(ret[i + 1] - ret[i])/100 for  i in range(num)]10    11 ret = red_packet(100, 10)
12 print(ret)

 

 

產生器版

 1 import random 2  3  4 def red_packet(money, num): 5     ret = random.sample(range(1, money * 100), num - 1) 6     ret.extend([0, money * 100]) 7     ret.sort() 8      9     for i in range(num):10         yield (ret[i + 1] - ret[i]) / 10011 12 red_packet(100, 10)
