For anyone who was following this, here is the finished, non floating
point, program, after all the kind advice received has been incorporated
into it (hopefully I have the leap year logic right...):
# *** (7) MAIN BODY -- The Buck Starts Here! ***************
def isLeapYear(y):
if y % 4 == 0:
if y % 100 == 0 and y % 400 == 1:
answer = False
return answer
answer = True
return answer
answer = False
return answer
print "This program finds all leap years between any two
dates.";print;print
start = end = None
while start == None:
try:
start = int(raw_input("Enter yyyy for beginning year : "))
end = int(raw_input("Enter yyyy for ending year : "))
except ValueError:
print;print "YEAR must be a integer number -- TRY AGAIN!"
start = end = None
if 1 <= start < end:
print; print
for y in range(start, end + 1):
answer = isLeapYear(y)
if answer == True:
print y, "--leap year!"
print "Done!"
*** EXECUTION ***
>>>
This program finds all leap years between any two dates.
Enter yyyy for beginning year : 1900
Enter yyyy for ending year : 2000
1900 --leap year!
1904 --leap year!
1908 --leap year!
1912 --leap year!
1916 --leap year!
1920 --leap year!
1924 --leap year!
1928 --leap year!
1932 --leap year!
1936 --leap year!
1940 --leap year!
1944 --leap year!
1948 --leap year!
1952 --leap year!
1956 --leap year!
1960 --leap year!
1964 --leap year!
1968 --leap year!
1972 --leap year!
1976 --leap year!
1980 --leap year!
1984 --leap year!
1988 --leap year!
