20 sum()函数及自定义函数复习（学习啊）

 1 def func(lst):
 2     sum = 0
 3     avg = 0
 4     for i in range(len(lst)):
 5         sum += lst[i]
 6         avg = sum/len(lst)
 7     return (sum,avg)
 8     # print(sum,avg)
 9 
10 l = [1,2,3,4,5]
11 print(func(l))
12 
13 2）进阶版
14 def getMaxMinAvgoflist(list):
15     Max = max(list)
16     Min = min(list)
17     sum = 0.0
18     for i in range(len(list)):
19         sum += list[i]
20         Avg = 1.0*sum/len(list)
21     print('max:{},min:{},ave:{}'.format(Max,Min,Avg))
22  # return  (Max,Min,Avg)  # 函数的返回值为元组
23 
24 l = []
25 geshu = int(input('请输入你需要的个数:'))
26 for i in range(geshu):
27     temp = input('请输入%d个数:'%(i+1))
28     temp = float(temp)
29     l.append(temp)
30 
31 getMaxMinAvgoflist(l)
