How To Find Difference Between Two Dates In Terms Of Day By Getting Date As User Input

I need to find the difference between two dates in terms of days by getting date as a user input. I tried to get date using raw_input but I'm getting an error. I'm using 2.7 versio

Solution 1:

You'll need to parse those dates into something a little more meaningful. Use the datetime.datetime.strptime() method:

from datetime import datetime

day1 = raw_input("enter the date in this format (yyyy:mm:dd)")
day2 = raw_input("enter the date in this format (yyyy:mm:dd)")
day1 = datetime.strptime(day1, '%Y:%m:%d').date()
day2 = datetime.strptime(day2, '%Y:%m:%d').date()
diff = day2 - day1
print diff.days

The datetime.datetime.date() method returns just the date portion of the resulting datetime object.

Solution 2:

If you are expecting the input in the form "yyyy:mm:dd", you cannot simply cast it to int.

Besides strptime, you can parse the input by yourself.

day1 = [int(i) for i in raw_input('...').split(':')]
d1 = datetime.date(*day1) 
day2 = [int(i) for i in raw_input('...').split(':')]
d2 = datetime.date(*day2) 
diff = d2 - d1
print diff.days

Thanks to @JF Sebastian, even simpler way using lambda by defining:

str2date = lambda s: datetime.date(*map(int, s.split(':')))

Simply call:

date = str2date(raw_input('...'))

Solution 3:

from datetime import date
import datetime

date1= datetime.date.today()
date_1=print(date1.strftime("The date of order: %d/%m/%Y"))

year = int(input('Enter a year: '))
month = int(input('Enter a month: '))
day = int(input('Enter a day: '))

date2 = datetime.date(year, month, day)
date_2= print(date2.strftime("Payment due date: %d/%m/%Y"))
difference=(date2-date1).days

print("The number of days for payment is: ", difference)

Its a program that allows a the user to find the difference between today's date and the input date from the user, in DAYS
