Question

我有以下代码：

init()

我收到以下错误：

from datetime import datetime as dt
import time
import datetime

TODAY_DATE = datetime.date.today()
THREE_MONTH = datetime.timedelta(weeks=12)
FOUR_MONTH = datetime.timedelta(weeks=16)
START_DAY = TODAY_DATE - FOUR_MONTH
END_DAY = TODAY_DATE - THREE_MONTH 

x = agent_coll_obj.find({ "created_at": {"$gte" : datetime.datetime(START_DAY), 
                                             "$lt": datetime.datetime(END_DAY) }})
print x

我试图以此SO question为指导。我试图只使用整个日期而不是每个日期的年，月和日变量。

Answer 1

from datetime import datetime as dt
import time
import datetime

TODAY_DATE = datetime.date.today()
THREE_MONTH = datetime.timedelta(weeks=12)
FOUR_MONTH = datetime.timedelta(weeks=16)
START_DAY = TODAY_DATE - FOUR_MONTH
END_DAY = TODAY_DATE - THREE_MONTH 

x = agent_coll_obj.find({ "created_at": {"$gte" : START_DAY, 
                                         "$lt": END_DAY }})
print x

您可以像这样使用datetime.datetime：

In [2]: datetime.datetime?
Docstring:
datetime(year, month, day[, hour[, minute[, second[, microsecond[,tzinfo]]]]])

The year, month and day arguments are required. tzinfo may be None, or an
instance of a tzinfo subclass. The remaining arguments may be ints or longs.
File:      /usr/local/opt/pyenv/versions/2.7.8/lib/python2.7/lib-dynload  /datetime.so
Type:      type

Answer 2

datetime.datetime函数需要specify年，月，日。

pymongo datetime TypeError：需要一个整数
