python while循环语句及练习题

#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')


#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')


#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')


#求1-100的所有数的和

n = 1
s = 0
while n < 101 :
    s = s + n
    n = n + 1

print(s)


#求1-2+3-4+5...99的所有数的和

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