【问题描述】：

我有以下代码：

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

我收到以下错误：

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

我试图以此 SO question 作为指导。我试图只使用整个日期，而不是为每个日期设置年、月和日的变量。

datetime.datetime函数需要specify年月日。

【解决方案2】：

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

你可以像这样使用 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.

Type:      type
