  • 流程控制之while(2)

    1. 使用while循环输出1 2 3 4 5 6     8 10
    count = 0
    while count < 10:
    count += 1
    if count == 7 or count == 9:
    continue
    print(count)
    2.求1-100的所有数的和
    num = 0
    count = 1
    while count <= 100:
    num = num+ count #num+=count
    count += 1
    print(num)
    3. 输出 1-100 内的所有奇数
    count = 0
    while count <100:
    count+=1
    if count%2==1:
    print(count)
    4. 输出 1-100 内的所有偶数
    count = 0
    while count <100:
    count+=1
    if count%2==0:
    print(count)
    5. 求1-2+3-4+5 ... 99的所有数的和
    num = 0
    count = 1
    while count <= 100:
    if count%2==0:
    num = num-count #num-=count
    elif count%2==1:
    num = num+ count #num+=count
    count += 1
    print(num)
    6.用户登陆(三次机会重试)
    name = "sean"
    pwd ="11"
    count = 0
    while count <3:
    inp_name = input('your name:')
    inp_pwd =input('your pwd:')
    if inp_name == name and inp_pwd == pwd:
    print('success')
    break
    else:
    print('try again')
    count +=1
    else:
    print('账号已锁定,请30分钟后再次尝试')
    7:猜年龄游戏:允许用户最多尝试3次,3次都没猜对的话,就直接退出,如果猜对了,打印恭喜信息并退出
    age_of_sean='18'
    count=0
    while count < 3:
    age = input('age_of_sean is:')
    if age == age_of_sean:
    print("It's good")
    break
    else:
    print('Try again')
    count+=1
    else:
    print('本轮游戏结束,下次加油!')
    8:猜年龄游戏升级版
    要求:
    允许用户最多尝试3次
    每尝试3次后,如果还没猜对,就问用户是否还想继续玩,如果回答Y或y, 就继续让其猜3次,以此往复,如果回答N或n,就退出程序
    如何猜对了,就直接退出
    age_of_sean='18'
    count=0
    while True:
    if count == 3:
    choice=input('如果继续,请输入Y或y,否则输入N或n退出: ')
    if choice == 'Y' or choice == 'y': #区分大小写
    count=0
    else:
    print('游戏结束,下次继续加油哦')
    break
    age=input('age_of_sean is: ')
    if age == age_of_sean:
    print("It's good")
    break
    count+=1
