Python3 练习题

创建一个程序，程序提示用户在while循环中输入数值，并根据输入的数值逐步构建一个列表。用户结束输入（按Enter键）时，打印出输入的数值本身、输入数值个数、输入数值和、中间值、最小值、最大值及平均值。

运行实例：

simple counter

input integer:5

input integer:55

input integer:fe

invalid literal for int() with base 10: 'fe'

input integer:100

input integer:40

input integer:

numbers: [5, 55, 100, 40]

count= 4 total= 200 zjz= 77.5 min= 5 max= 100 avg= 50.0

 

print("simple counter")
count=0
total=0
clist=[]
while True:
   line=input("input integer:")
   if line:
      try:
         number=int(line)
         clist.append(number)
         count+=1
         total+=number
      except ValueError as err:
         print(err)
         continue
   else:
      break

if count:
   print("numbers:",clist)
   clist.sort()
   if len(clist)%2!=0:
      zjz=clist[len(clist)//2+1]
   else:
      zjz=(clist[len(clist)//2]+clist[len(clist)//2+1])/2
   #print("count=",count,"total=",total,"min=",clist[0],"max=",clist[len(clist)-1],"avg=",total/count)
   print("count=",count,"total=",total,"zjz=",zjz,"min=",min(clist),"max=",max(clist),"avg=",total/count)
