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 + 1 print(s)
3、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----‘)
4、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----‘)
5、用户登陆（三次机会重试）
count = 0 while count < 3: user = input(‘>>>‘) pwd = input(‘>>>‘) if user == ‘alex‘ and pwd == ‘123‘: print(‘欢迎登陆‘) print(‘..........‘) break else: print(‘用户名或者密码错误‘) count = count + 1
6、求1-2+3-4+5 ... 99的所有数的和
n = 1 s = 0 # s是之前所有数的总和 while n < 100: temp = n % 2 if temp == 0: s = s - n else: s = s + n n = n + 1 print(s)
