Or the "old school" (lower overhead, if it matters) method...
或者“老派”（较低的开销，如果重要的话）方法......
import time
time.localtime(time.time())[2]
time.localtime() returns a tuple containing all of the elements of a timestamp.
time.localtime() 返回一个包含时间戳所有元素的元组。

This is similar to the answer by programmersbook. It uses datetime.daterather than datetime.datetime.
这类似于程序员手册的答案。它使用datetime.date而不是datetime.datetime.
>>> import datetime
>>> datetime.date.today().day
8
