1.编写一个函数，求1+2+3+...+N

def sum1(n):
    sum1 = 0

    for i in range(1,n+1):
        sum1 += i
    print(sum1)
sum1(7)

2、编写一个函数，求多个数中的最大值

lst = []
str = raw_input("请输入数值，用空格隔开:")
lst1 = str.split(" ")
i = 0
while i <= len(lst1)+1:
    lst.append(int(lst1.pop()))
    i += 1
def sum(list):
    s = 0
    for x in list:
        s += x
    return s

3、编写一个函数，实现摇色子的功能，打印N个色子的点数和

import random
def sum1(n):
    sum3 = 0
    for i in range(n):
        sum2 = random.randint(1, 6)
        sum3 +=sum2
    print("骰子和:",sum3 )
sum1(5) 

5、编写一个函数，求三个数中的最大值

def max1 (a,b,c):
    if a>b and a>c:
        print("最大值是:",a)
    if b>a and b>c:
        print("最大值是:", b)
    if c>a and c>b:
        print("最大值是:", c)
max1(1,2,3

7.编写一个函数，求多个数的平均值

lst = []
str = raw_input("请输入数值，用空格隔开:")
lst1 = str.split(" ")
i = 0
while i <= len(lst1)+1:
    lst.append(int(lst1.pop()))
    i += 1
def sum(list):
    s = 0
    for x in list:
        s += x
    return s




def average(list):
    avg = 0
    avg = sum(list)/(len(list)*1.0) 
    return avg

8、编写一个函数，默认求10的阶层，也可以求其他数的阶层

def my_fun(n):
    jie =1
    for i in range(1,n+1):
        jie1 =jie*i
        jie =jie1
    print(jie1)
my_fun(10)
