查找列表中的n个数字的平均值

Question

除了当用户键入N结束while循环时，一切都在工作，它不会进入For语句（当您运行该程序时发生这种情况，在shell中工作正常并且在py中）。

potato = [] 
count = 0 
avg = 0 

question = input('Finding averages, continue? Y or N: ') 
while question == 'Y' and count <= 12: 
    num = int(input('Enter a number: ')) 
    potato.append(num) 
    count += 1 
    question = input('Continue? Y or N: ') 

for fries in potato: 
    avg = sum(potato)/count 
    print(fries,fries-avg) 

print('average is: ' + str(avg)) 

Answer 1

直到我将输入更改为raw_input之前，它一直在为我打破。现在退出while循环，当输入不是Y：

question = raw_input('Finding averages, continue? Y or N: ') 

Answer 2

#!/usr/bin/python 

my_list=[] 
val=int 
sum1=int 
n=int(input('Enter the limit:')) 
for i in range(0,n): 
    val=int(input('number:')) 
    my_list.append(val) 
sum1=sum(my_list) 
print sum1 
res=float(sum1/n) 
print 'The average is:',res
