测试题目摘自

一、使用while循环输入1-10，其中不包括7

1 number = 02 while number<10:3     number +=14     if number == 7:5         continue6     print(number)

二、求1-100的所有数的和

1 count = 12 sum = 03 flag =True4 while flag:5     sum = sum + count6     count += 17     if count > 100:8         break9 print('1-100的总和是：',sum)

三、输出1-100内的所有奇数

1 odd = 12 while odd <=100:3     print(odd)4     odd += 2

四、输出1-100内的所有偶数

1 even = 02 while even <=100:3     even += 24     if even > 100:5         continue6     print(even)

五、求1-2+3-4+5...99的所有数的和

1 odd = 1 2 even = 2 3 odd_sum = 0 4 even_sum = 0 5 while odd < 100: 6     odd_sum = odd_sum + odd 7     odd += 2 8 while even < 100: 9     even_sum = even_sum + even10     even += 211 print('odd_sum:',odd_sum,'even_sum:',even_sum)12 count_sum = odd_sum - even_sum13 print("1-2+3-4+5...99的所有数的和是:",count_sum)

六、用户登陆（三次机会重试）

count_number = 3name = 'admin'password = 'admin'flag = Truewhile flag:    user_name = input("请输入你的用户名:")    user_password = input("请输入你的登录密码:")    if user_name==name and user_password==password:        print('用户名与登录密码输入正确，用户登录成功')        break    if count_number == 3:        print('用户名或登录密码输入不一致，你还有两次机会')    elif count_number == 2:        print('用户名或登录密码输入不一致，你还有一次机会')    else:        print('用户名或登录密码输入不一致，你的机会已经用完，请过5分钟后再试')    count_number -= 1    if count_number < 1:        break
