  1. 使用while循环输出1 2 3 4 5 6 8 9 10

    count = 1
    while count < 11:
        if count == 7:
            count += 1
            continue
        else:
            print(count)
            count += 1
    
  2. 求1-100的所有数的和

    sum1 = 0
    count = 1
    while count < 101:
        sum1 = sum1 + count
        count += 1
    print(sum1) #5050
    
  3. 输出 1-100 内的所有奇数

n = 1
sum1 = 0
while n <= 50:
    count = 2 * n - 1
    sum1 += count
    n += 1
print(sum1)  #2500
  1. 输出 1-100 内的所有偶数

    n = 1
    sum1 = 0
    while n <= 50:
        count = 2 * n
        sum1 += count
        n += 1
    print(sum1) #2550
    
  2. 求1-2+3-4+5 ... 99的所有数的和

    n = 1
    sum1 = 0
    while n < 50:
        count0 = 2 * n - 1
        count1 = 2 * n
        sum0 = count0 - count1
        sum1 += sum0
        n += 1
    print(sum1)
    
  3. 用户登陆(三次机会重试)

username = 'egon'
password = '123'
count = 0
while True:
    if count == 3:
        print('输错三次,用户锁定!')
        break
    user_name = input('请输入用户名:').strip()
    user_pwd = input('请输入密码:').strip()
    if username == user_name and user_pwd == password:
        print('登录成功!')
        break
    else:
        print('用户名或密码错误!')
        count += 1

7:猜年龄游戏
要求:
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

egon_age = '18'
count = 0
while True:
    if count == 3:
        break
    inp_age = input('请输入猜测年龄:').strip()
    if inp_age == egon_age:
        print('恭喜你猜对了!')
        break
    else:
        print('猜错啦')
        count += 1

8:猜年龄游戏升级版(选做题)
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

egon_age = '18'
count = 0
while True:
    if count == 3:
        info = input('请文是否还想继续猜呢(y or n):').strip()
        info = info.lower()
        if info == 'n':
            break
        elif info != 'n' and info != 'y':
            print('请输入正确的的字母!')
            continue
        else:
            count = 0
    inp_age = input('请输入猜测年龄:').strip()
    if inp_age == egon_age:
        print('恭喜你猜对了!')
        break
    else:
        print('猜错啦')
        count += 1
