pymongo datetime TypeError: an integer is required

Question

I have the following code:

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

I get the following error:

Traceback (most recent call last):
  File "main.py", line 212, in <module>
    program.runProgram()
  File "main.py", line 61, in runProgram
    report.RcreateReport()
  File "/Users/dwstein_old/Dropbox/hkpr_reports/report.py", line 105, in RcreateReport
    x = agent_coll_obj.find({ "created_at": {"$gte" : datetime.datetime(START_DAY), 
TypeError: an integer is required

I was trying to use this SO question as a guide. I'm trying to just use the whole date as opposed to having variables for the year, month, and day for each date.

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

you can use datetime.datetime like this:

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.

您需要为datetime.datetime函数指定年，月，日。
