移动一个字符串从一个列表到另一个

Question

每当我运行程序时，它要么错误

Traceback (most recent call last): 
    File "C:\Users\mrosales\Downloads\Rock Paper Sissor Tornament.py", line 46, in <module> 
    Temp = ClassList[Random2] 
IndexError: list index out of range 

Traceback (most recent call last): 
    File "C:\Users\mrosales\Downloads\Rock Paper Sissor Tornament.py", line 60, in <module> 
    Temp = ClassList[Random2] 
IndexError: list index out of range 

我的代码是关于从一个列表移动串到另一个形成tornamnet的一套游戏大作

import random 
import time 
Temp = (" ") 
ClassList = ['Noah','Simone','Ji Ho','Thanh','Nathanial','Soo','Mickel','Tuan'] 
Match1 = [], Match2 = [], Match3 = [] ,Match4 = [] 
Random1 = random.randrange(0,len(ClassList)) 
Random2 = random.randrange(0,len(ClassList)) 
while Random1 == Random2: 
    Random1 = random.randrange(0,len(ClassList)) 

time.sleep(1) 
Temp = ClassList[Random1] 
Match1.append(Temp) 
del ClassList[Random1] 
Temp = ClassList[Random2] 
del ClassList[Random2] 
Match1.append(Temp) 

print(Match1) 
Random1 = random.randrange(0,len(ClassList)) 
Random2 = random.randrange(0,len(ClassList)) 
while Random1 == Random2: 
    Random1 = random.randrange(0,len(ClassList)) 

time.sleep(1) 
Temp = ClassList[Random1] 
Match2.append(Temp) 
del ClassList[Random1] 
Temp = ClassList[Random2] 
del ClassList[Random2] 
Match2.append(Temp) 

print(Match2) 
Random1 = random.randrange(0,len(ClassList)) 
Random2 = random.randrange(0,len(ClassList)) 
while Random1 == Random2: 
    Random1 = random.randrange(0,len(ClassList)) 

time.sleep(1) 
Temp = ClassList[Random1] 
Match3.append(Temp) 
del ClassList[Random1] 
Temp = ClassList[Random2] 
del ClassList[Random2] 
Match3.append(Temp) 

print(Match3) 
Random1 = random.randrange(0,len(ClassList)) 
Random2 = random.randrange(0,len(ClassList)) 
while Random1 == Random2: 
    Random1 = random.randrange(0,len(ClassList)) 

time.sleep(1) 
Temp = ClassList[Random1] 
Match4.append(Temp) 
del ClassList[Random1] 
Temp = ClassList[Random2] 
del ClassList[Random2] 
Match4.append(Temp) 

print(Match4) 
Random1 = random.randrange(0,len(ClassList)) 
Random2 = random.randrange(0,len(ClassList)) 
while Random1 == Random2: 
    Random1 = random.randrange(0,len(ClassList)) 

print ("The current match ups are...") 
print (Temp) 
time.sleep(1) 
print (Match1, Match2, Match3, Match4) 

任何人能发现我可能已经放置，如果他们愿意的话，纠正错误？

Answer 1

从我所收集你的代码是试图做的，我相信下面的代码将实现它。它比较短，但是基本上可以做到没有崩溃的情况。

import random 

ClassList = ['Noah', 'Simone', 'Ji Ho', 'Thanh', 'Nathanial', 'Soo', 'Mickel', 'Tuan'] 

# Randomise list order 
random.shuffle(ClassList) 

# Remove last 2 elements from list and add to new match lists 
Match1 = [ClassList.pop(), ClassList.pop()] 
Match2 = [ClassList.pop(), ClassList.pop()] 
Match3 = [ClassList.pop(), ClassList.pop()] 
Match4 = [ClassList.pop(), ClassList.pop()] 

print(Match1, Match2, Match3, Match4) 

请注意，如果您多次运行此操作，您将看到它确实会给出不同的“匹配装置”。

解决方案1：
del ClassList[Random1]后第二Temp分配。

解决方案2：
Random2 = random.randrange(0,len(ClassList)-1)将解决您的问题，然后您不需要Random1 != Random2您的情况。

更重要的是：
应该清理一下你的代码...

temp = classList.pop(random1) 

相当于

temp = classList[random1] 
del classList[random1] 

使用照顾重复代码的功能：

def get_random(): 
    random_index = random.randrange(0,len(classList)) 
    return classList.pop(random_index) 

match1 = [get_ramdom(), get_random()] 

不要根据01不要使用大写变量名

Answer 3

，你通过它迭代要修改你的类列表。当它抛出错误时，你的班级中没有人会选择len（ClassList）0。

如果我明白你正在尝试做的，你可以只创建另一个列表，并为您遍历原来的列表来跟踪谁一直匹配的追加名字给它。或甚至更好地使用random.shuffle

import random 
import time 
classlist = ['Noah','Simone','Ji Ho','Thanh','Nathanial','Soo','Mickel','Tuan'] 
from random import shuffle 

def get_random(classlist): 
    shuffle(classlist) 
    while classlist: 
    yield classlist.pop() 

matches = [] 
match = [] 

for player in get_random(classlist): 
    if len(match) <= 1: 
     #print "Adding %s" %player 
     match.append(player) 
     if len(match) == 2: 
      matches.append(match) 
      #print "Match %s is full" %len(matches) 
      match = [] 

for x in range(0,len(matches)): 
    print "Match %s: %s" %(x,matches[x])
