Enter a year at will from the keyboard with Python and work out how many days it is. For example, if you enter 20 19, you must first judge whether it is a leap year.

#? Century leap year: the century leap year can be divisible by 400.

#? Ordinary leap year: a year divisible by 4 but not by 100 is an ordinary leap year.

#? There are 366 days in leap years and only 365 days in other years.

What if? Int (year)? %? 400? ==? 0:

Return? real

Elif? Int (year)? %? 100? ! =0? And then what? Int (year)? %? 4? ==? 0:

Return? real

Otherwise:

Return? wrong

def？ Calculate the number of days in a year (year):

Leap? =? Leap year or non-leap year

What if? Leap:

How many days? =? 366

Run? =? "yes"

Otherwise:

How many days? =? 365

Run? =? "no"

Print("{} year {} is a leap year with {} days. " . Format (year,? Run? Day))

What if? __name__？ ==? " __main__ "

Print ("Enter year:")

n？ =? Enter ()

Calculate_days_of_year(n) Run the above code and enter 20 19 to get the following results:
