2.奇数和

x = 1
heji = 0
while True:
    if x < 100 :
        heji += x
        print(heji)
        x += 2

3.猜年龄

x = 0
z = 19
while True:
    if x < 3:
        y = int(input('请输入年龄:'))
        x += 1
        if y < z:
            print('猜小了')
            print(f'你还有{3 - x}次机会')
        elif y > z:
            print('猜大了')
            print(f'你还有{3 - x}次机会')
        else:
            print('猜对了')
            break
    elif x == 3:
        xuanzhe = input('您是否还继续(yes/no?)')
        if xuanzhe not in ['Y','N','y','n','yes','no']:
            continue
        if xuanzhe in ['Y','y','yes']:
            x = 0
        else:
            break
