python - 类型错误 : 'int' object is not subscriptable

Question

我正在尝试创建一个简单的程序，根据命理告诉你你的幸运数字。我不断收到此错误:

File "number.py", line 12, in <module>
    sumln = (int(sumall[0])+int(sumall[1]))
TypeError: 'int' object is not subscriptable

我的脚本是:

birthday = raw_input("When is your birthday(mm/dd/yyyy)? ")
summ = (int(birthday[0])+int(birthday[1]))
sumd = (int(birthday[3])+int(birthday[4]))
sumy= (int(birthday[6])+int(birthday[7])+int(birthday[8])+int(birthday[9]))
sumall = summ + sumd + sumy
print "The sum of your numbers is", sumall
sumln = (int(sumall[0])+int(sumall[1]))
print "Your lucky number is", sumln`   

Answer 1

错误正是它所说的；当 sumall 是一个 int 并且没有任何意义时，您正在尝试使用 sumall[0]。你认为 sumall 应该是什么？
