Question

我对编码很新，请原谅任何基本错误。我一直在研究这段使用Python日历模块生成开始日期的代码。一切都很顺利，直到我意识到我还需要一个结束日期。我尝试手动将1添加到开始日期，并且我意识到当我打印输出时，一旦它到达月底就不会起作用。这是我得到的错误输出。显然，12月没有32天。开课日期是2015-12-31。截止日期为2015-12-32。我一直在阅读日历模块上的文档，但我还没有看到任何关于如何使其正常工作的内容（这对我来说很有意义）。这就是我到目前为止所做的：

import requests
import json 
import calendar

cal = calendar.Calendar()
for year in range(2015,2016):
    for month in range(1,13):
        monthdays = [d for d in cal.itermonthdays(year,month) if d != 0]
        for day in monthdays:
            str_year = str(year)
            if month < 10:
                str_month = "0" + str(month)
                # print(str_month)
            else:
                str_month = str(month)
                # print(str_month)
            if day < 10:
                str_StartDay = "0" + str(day)
                int_EndDay = day + 1
                if int_EndDay < 10:
                    str_EndDay = "0" + str(int_EndDay)
                else:
                    str_EndDay = str(int_EndDay)
            else:
                str_StartDay = str(day)
                int_EndDay = day + 1
                str_EndDay = str(int_EndDay)
                # print(str_day)
            _STARTDATE = str_year + "-" + str_month + "-" + str_StartDay
            _ENDDATE = str_year + "-" + str_month + "-" + str_EndDay
            # print(_DATE)
            #fun_Phase1(_DATE)
            print("Start date is " + _STARTDATE)
            print("End date is " + _ENDDATE)

提前致谢。

谢谢克劳斯D.你指出了我正确的方向。我最终使用datetime来解决这个问题。这是代码。希望这能节省一些时间。

import requests
import json 
import calendar
import datetime

cal = calendar.Calendar()
for year in range(2015,2016):
    for month in range(1,13):
        monthdays = [d for d in cal.itermonthdays(year,month) if d != 0]
        for day in monthdays:
            str_year = str(year)
            int_year = int(year)
            if month < 10:
                str_month = "0" + str(month)
                int_month = int(month)
                # print(str_month)
            else:
                str_month = str(month)
                int_month = int(month)
                # print(str_month)
            if day < 10:
                str_StartDay = "0" + str(day)
                int_day = int(day)
            else:
                str_StartDay = str(day)
                int_day = int(day)
                # print(str_day)
            _MYDATE = datetime.date(int_year,int_month,int_day)
            str_MYDATE = str(_MYDATE)
            print(str_MYDATE)
            _MYDATEPLUSONE = _MYDATE + datetime.timedelta(days=1)
            str_MYDATEPLUSONE = str(_MYDATEPLUSONE)
            print(str_MYDATEPLUSONE)
            print("Start date is " + str_MYDATE)
            print("End date is " + str_MYDATEPLUSONE)
