pymongo datetime TypeError：必須為整數

Question

我有以下代碼：

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

我收到以下錯誤：

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

我正在嘗試將此SO問題用作指導。 我試圖只使用整個日期，而不是每個日期的年，月和日都有變量。

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

您可以像這樣使用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.

Type:      type

Answer 2

您需要為datetime.datetime函數指定年，月，日。
