Sweepstake發電機

Question

即時通訊新手和我正在撕裂我的頭髮在這個循環的問題。我想隨機將一個國家分配給一個人參加抽獎比賽的名單。一旦一個國家被分配了，那麼它應該不再被分配到循環的進一步迭代中。循環應該經歷整個人員列表（比國家列表短）。是的，我知道代碼可能更簡單，但這只是我放棄的一點。請指教！

import random 
filez = open ('C:/Users/Andy/Desktop/countrys.txt', 'r') 
countries = filez.readlines() 

filez2 = open ('C:/Users/Andy/Desktop/names.txt', 'r') 
people = filez2.readlines() 

def chop (x): #gets rid of wierd added bits 
    for i in range(0, len(x)): 
     x[i] = x[i] [:-1] 
    return x 

chop(countries) 
chop(people) 

def assign (y): 
    used = [] 
    for person in range(0, len(y)): 
     num = random.randint(0, len(countries))  
     if num not in used: 
      print (people[person] + " gets " + countries[num]) 
      used.append(num) 
     else: 
      num = random.randint(0, len(countries)) 
      print (people[person] + " gets " + countries[num]) 
      used.append(num) 


assign(people) 

Answer 1

一個可能的解決辦法是：

random.shuffle(countries) 
assignments = list(zip(people, countries)) 

，這將給你的元組(person, country)名單。
