初创博客及初识python！

day9作业：

1.

 

 

# 使用while循环输入 1 2 3 4 5 6    8 9 10

n=1
while n < 11:
    if n ==7:
        pass
    else:
        print(n)
    n=n+1
print("-----end-----")

 

2.

# 输出 1-100 内的所有偶数

n = 1
while n < 101:
    temp = n % 2
    if temp == 0:
        print(n)
    else:
        pass
    n = n + 1
print("------end------")

 

3.

# 求 1-100 的所有数的和：

n = 1
s = 0
while n < 101:
    n = n + 1
    s = s + n
print(s)

 

4.

# 求 1-2+3-4+5……99的所有数的总和：

n = 1
s = 0     
while n < 100:
    temp = n % 2
    if temp == 0:
        s = s - n
    n = n + 1
print(s)

 

5.

 

# 输出 1-100 内的所有奇数 n = 1 while n < 101: temp = n % 2 if temp == 0: pass else: print(n) n = n + 1 print("------end------")
