有大佬帮一下吗，都是一位数还行，有两位的我就不会了/(ㄒoㄒ)/~~

-----------------------------------------这下面是我写的处理不了一位数以上的----------------------------------

shuzhi=[]
sum=0
shuzhi.extend(input("请输入n个数值:"))
chang=len(shuzhi)
shuzhi=[int(x) for x in shuzhi]
for i in range(chang):
    print(shuzhi[i],end=",")
    sum=sum+shuzhi[i]
print('的平均值=',sum/chang)
 

python 字符串有个split()函数，用来分割字符串的。举个例子来说，str="1,2,12,2",那么str.split(",")的结果是"1","2","12","2".所以你只要吧切割字符串的部分换成split就可以了

谢谢
