Question

I have code like this:

import time
from datetime import date

startyear = raw_input("start year: ")
startmonth = raw_input("start month: ")
startday = raw_input("start day: ")
endyear = raw_input("end year: ")
endmonth = raw_input("end month: ")
endday = raw_input("end day: ")

startdate = date(int(startyear), int(startmonth), int(startday))
while startdate < date(int(endyear), int(endmonth), int(endday)):
    print startdate
    startdate = startdate.replace(day=startdate.day + 1)

This code:

1. gets the start and end date by manual input
2. generate a list of dates between them

But the problem is, if I set up the date like, for example,

startdate: 2012-10-28
enddate: 2012-11-4

the output would be like:

2012-10-28
2012-10-29
2012-10-30
2012-10-31
ValueError: day is out of range for month

I want the output to be like:

2012-10-28
2012-10-29
2012-10-30
2012-10-31
2012-11-01
2012-11-02
2012-11-03
2012-11-04

So I want the dates to go through month. How can I do it?

Answer 1

Instead of startdate.replace(), you should use timedelta…

from datetime import date, timedelta
# Get input here...
while startdate < date(int(endyear), int(endmonth), int(endday)):
    print startdate
    startdate += timedelta(days=1)
