4.2. Example of integer arithmetic

The code

 
#!/usr/bin/env python
days = int(raw_input("Enter days: "))
months = days / 30
days = days % 30
print "Months = %d Days = %d" % (months, days)

The output

 
$ ./integer.py
Enter days: 265
Months = 8 Days = 25

In the first line I am taking the input of days, then getting the months and days and at last printing them. You can do it in a easy way

 
#!/usr/bin/env python
days = int(raw_input("Enter days: "))
print "Months = %d Days = %d" % (divmod(days, 30))

The divmod(num1, num2) function returns two values , first is the division of num1 and num2 and in second the modulo of num1 and num2.
