5 函数求最大 、小、个数的练习

 1 def findmax(*l):
 2     if l == []:
 3         return
 4     else:
 5         Max = l[0]
 6         for i in l:
 7             if i > Max:
 8                 Max = i
 9         return Max
10 
11 def findmin(*l):
12     if l == []:
13         return
14     else:
15         Min = l[0]
16         for i in l:
17             if i < Min:
18                 Min = i
19         return Min
20 
21 def findlen(*l):
22     a = len(l)
23     return a
24 
25 x = input('请输入数字，并用空格隔开:').split()   #.split()用于分隔关对字符串进行切片操作
26 last = []
27 for i in x:
28     last.append(int(i))
29 print('max:',findmax(*last))
30 print('min:',findmin(*last))
31 print('max:',findlen(*last))
