[Tutor] What's the invalid syntax?

[Nathan Pinno]

Hey all,
 
What's the invalid syntax in the following code? I tried figuring it out by
myself, and I couldn't.
 
# This program finds the date of Easter Sunday between the years 1900 &
2099.
# By Nathan Pinno
# Inspired by Programming and Problem Solving with Java, 1st ed., question
3, page 207.
def date():
    int year
    year = int(raw_input("Year please: "))
    if (year < 1900 || year > 2099):
        print year, " is invalid. Please enter a year between 1900 & 2099."
    else:
        if (year == 1954 || year == 1981 || year == 2049 || year == 2076): #
For the years when the calculation would be 1 week late.
            int a, b, c, d, e, f
            a = year % 19
            b = year % 4
            c = year % 7
            d = (19 * a + 24) % 30
            e = (2 * b + 4 * c + 6 * d + 5) % 7
            f = (22 + d + e) - 7
            if (f < 31): # To see if the date is in March or April.
                print "Easter Sunday is March ", f, "."
            else:
                print "Easter Sunday is April ", (f-31), "."
        else: # For all other years.
            int a, b, c, d, e, f
            a = year % 19
            b = year % 4
            c = year % 7
            d = (19 * a + 24) % 30
            e = (2 * b + 4 * c + 6 * d + 5) % 7
            f = (22 + d + e)
            if (f < 31): # Same as above.
               print "Easter Sunday is March ", f, "."
            else:
               print "Easter Sunday is April ", (f-31), "."
date()
            
The editor highlights the word year in the line:
 
int year
 
after I hit okay when this message pops up:
 
Invalid syntax.
 
Thanks in advance,
Nathan Pinno
