这是我的代码，用于试图弄清访问18+网站的人的年龄（https://www.reddit.com/r/beginnerprojects/comments/3hrbpo/project_verifying_a_users_age/），我有两个问题。1）我不知道如何将列表网站添加到我的else字符串中。2）我想知道是否可以为currentDate导入当前年份，这样就不必手动将其输入。再次感谢您，感谢您的草率代码，我还是Python的新手！

import datetime


websites = ["www.youtube.com", "www.quora.com",    "www.twitter.com"]



while True:
    currentDate = 2015
    print("WARNING: THIS WEBSITE IS FOR 18 YEARS OR UP")
    userAge = int(raw_input("What is the year of your birth? "))
    if userAge + 18 <= currentDate:
        print "Welcome!"
        break
    elif userAge + 18 > currentDate:
        print ("We're sorry, but this website isn't for you, try some of these websites: ")
        continue

干得好：

您希望date.today（）获得当前日期
您想使用string.format（）和string.join（）将列表连接在一起并将其内容插入输出中
无需该elif子句-else处理“其他”条件（因为您elif与您相反if）

代码：

from datetime import date

websites = ["www.youtube.com", "www.quora.com",    "www.twitter.com"]
while True:
    print("WARNING: THIS WEBSITE IS FOR 18 YEARS OR UP")
    userAge = int(raw_input("What is the year of your birth? "))
    if userAge + 18 <= date.today().year:
        print "Welcome!"
        break
    else:
        print ("We're sorry, but this website isn't for you, try some of these websites: {}".format(",".join(websites))
        continue
