陷入无线循环，help！

7-5题用while循环怎么写（Python)

，输入值后一直无限出一个值

age永远不等于'quit'啊，当然死循环。循环内部你都把q转换成整型了啊

while 1:
    age = input('how old are you')
    if age != 'quit':
        break
    else:
        if int(age)<3:
            print('you are free')
        elif int(age)>=3 and int(age) <= 12:
            print('10$')
        else:
            print('15$')
