Implement the basic algorithm
After we learned some basic hardware controls in the last chapter, let's make up our basic software lessons.
Enter the year to determine the leap year
A leap year is a noun in the Gregorian calendar. Common year: a year that is divisible by 4 but not by 100 is a common leap year. (2004 is a leap year, 1999 is not); Century years: leap years are those divisible by 400.
The code is as follows :(can be placed in main.py):
def is_leap_year(year):
if (year % 4) == 0 and (year % 100) != 0 or (year % 400) == 0: print("{0} is leap year".format(year)) else: print("{0} not is leap year".format(year))
first in the interpreter using runfile main.py and then run it in the repl
is_leap_year(int(input("input a leap year ")))
