1. Leap year (need to be optimized, can only be cycled once)

year = Int (input ("Please enter the number of years:"))ifYear% 4:    Print("not a leap year")#It can't be divisible by 4.Else:    ifYear% 400:        ifYear% 100:            Print("Leap Year")#That can be divisible by 4, but not divisible by 100.        Else:            Print("not a leap year")#Divisible by 4 and divisible by 100, but not evenly divisible .    Else:        Print("Leap Year")#Divisible by 4 can be divisible by 400.    

Elementary Turtle's Code:

temp = input ('Please enter a year:') while  nottemp.isdigit (): Temp= Input ("Sorry, your input is wrong, please enter an integer:") Year=Int (temp)ifyear/400 = = Int (year/400):    Print(temp +'is a leap year! ')Else:    if(YEAR/4 = = Int (YEAR/4)) and(year/100! = Int (year/100)):        Print(temp +'is a leap year! ')    Else:        Print(temp +'not a leap year! ')
