求解答!这种该怎么写

import random,sys
age=random.randint(1,100)
print(age)
con = 'y'
while con=='y':
    i=1
    while i<=4:
        guess = eval(input("请猜年龄："))
        if guess == age:
            print('猜对了，给你微信hhh')
            sys.exit()
        else:
            print('猜错了:')
        i+=1
    print('四次机会用完，是否继续（y/n)：')
    con = input()
print('可惜了，拜拜')
