你用的是python2?
如果是的话，把input改为raw_input

另外，

1. endings = ['st', 'nd', 'rd'] + 17 * ['th'] \
   
2.         + ['st', 'nd', 'rd'] +  7 * ['th'] \
   
3.         + ['st']

这句代码是干什么用的啊？

第32行
ordinal = str(day) + endings[day_number-1]

这句代码是干什么用的啊？

从1日到31日，每天序数的结尾，如1日是st，2日是nd

从下面的错误原因就可以看到是类型没有进行转换导致的。
