while循环语句习题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,求1 - 100的所有数的和
n = 1
s = 0
while n < 101: s = s + n n = n + 1print(s)
3,输出 1 - 100内的所有奇数
n = 1
while 1 < 101:
temp = n % 2
if temp == 0:
pass
else:
print(n)
n = n + 1
while语句简单例子
print("---end---")
4,输出 1 - 100内的所有偶数
n = 1
while 1 < 101:
temp = n % 2
if temp == 0:
print(n)
else:
pass
n = n + 1
print("---end---")
5,求1-2+99的所有数的和
s = 0
n = 1
while n < 101:
temple = n % 2
if temple == 0:
s = s - n
else:
s = s + n
n = n + 1
print(s)
6,⽤户登陆(三次机会重试)
count = 0
while count < 3:
user = input(">>>")
pwd = input(">>>")
if user == "321" and pwd == "123": print("欢迎登陆")
