Python 3错误(在我的打开列表中)仅返回三项

您好,我的跑马程序运行出错。本质上,我只想在最后一部分输入名称,它应该为每个名称起一个作用。用户输入XXX后,命名将停止,比赛开始。任何帮助都可以。我将向您展示该程序的运行方式。

我的错误只发生在E部分

import random

print ("Random number from 10-21 is : " )
print (random.randrange(10,21))


##get the average
def average(times):
 return sum(times) / len(times)


times = []
counter = 0

while counter < (1001):
 counter += 1
 times.append(random.randrange(10,21))

print (average(times))


## for one horse in the race
distance = 0
seconds = 1
while distance <= 10560:

 distance += (random.randrange(4,41))
 seconds += 1
print(distance)

##one horse running 1000 races 
seconds = 0
distance = 0
times = []
counter = 0

while counter < (1001):
 counter += 1
 while distance <= 10560:
  num = (random.randrange(4,41))
  distance += num
  seconds += 1
  times.append(seconds)

print("Part C, Average of horses time", average(times))
##function that adds the random distance the horse
def horse(x):
 b = random.randrange(4,41)
 x = x + b
 return x

##Part  D
number_of_ = int(input("How many horses are in the race: "))
distance = []
for i in range(number_of_):
 distance.append(0)
finishline = True
print(distance)
while finishline:
 for p in range(len(distance)):
  distance[p] = horse(distance[p])
 if max(distance) <= 10560:
  finishline = True
 else:
  finishline = False
print(distance)
print("The winner is" , max(distance))
#part E
name_of_horses = []
distance_of_horses = []
STOP = "XXX" 
names = input("Enter a name for each horse: ")
while names != STOP:
    name_of_horses.append(names)
    names = input("Enter a name for each horse: ")

for i in range(len(names)):
 distance_of_horses.append(0)
finishline = True
print(name_of_horses)
while finishline:
 for p in range(len(distance_of_horses)):
  distance_of_horses[p] = horse(distance_of_horses[p])

 if max(distance_of_horses) <= 10560:
  finishline = True
 else:
  finishline = False
print(distance_of_horses)
print("The winner is" , max(distance_of_horses))

下面提供的是程序当前返回的内容。我知道我是菜鸟,但任何帮助都可以。谢谢。

==================
Random number from 10-21 is : 
11
15.036963036963037
10567
Part C, Average of horses time 245.0
How many horses are in the race: 5
[0, 0, 0, 0, 0]
[10588, 10532, 10444, 10461, 10362]
The winner is 10588
Enter a name for each horse: dom
Enter a name for each horse: dom
Enter a name for each horse: dom

Enter a name for each horse: dom
Enter a name for each horse: dom
Enter a name for each horse: XXX
['dom', 'dom', 'dom', 'dom', 'dom', 'dom']
[10477, 10574, 10251]
The winner is 10574

1 个答案:

答案 0 :(得分:2)

问题出在第78行

for i in range(len(names)):
    distance_of_horses.append(0)

由于程序读取的名称被视为字符串(并且字符串是一个字符数组),因此会将您的字符串视为字符数组,在这种情况下,“ XXX”为3个字符,因此您的distance_of_horses当然会有3个值

经典的错误输入错误

注意:我不认为这应该在答案部分,但我还不能发表评论
