if ( Selection < 0) and (Selection > 3) condition behaves differently for input =4. Why?

def PrintBlue():
    print (" You chose Blue!\r\n")

def PrintRed():
    print (" You chose Red!\r\n")

def PrintOrange():
    print (" You chose Orange!\r\n")

def PrintYellow():
    print (" You chose Yellow!\r\n")

#Let's create a dictionary with unique key

ColorSelect = {
    0:PrintBlue,
    1:PrintRed,
    2:PrintOrange,
    3:PrintYellow
    }

Selection = 0

while (Selection != 4):
    print ("0.Blue")
    print ("1.Red")
    print ("2.Orange")
    print ("3.Yellow")
    try:
        Selection = int(input("Select a color option: "))
        x=0
        if ( Selection < 0) and (Selection > 3):
            raise KeyError(" Enter a number >=0 and <4)")
        else:
            ColorSelect[Selection]() # Run the function inside dictionary as well
    except KeyError:
        pass

Above is my python code. I am using 2.7 version. but after running I got different result for input =4. While I am expecting same result for Selection<0 or >3.Here is result look like:

0.Blue 1.Red 2.Orange 3.Yellow Select a color option: 5 0.Blue 1.Red 2.Orange 3.Yellow Select a color option: 4

Notice after I enter input =4 , python exits from run time.When I enter 0,1,2,3,5,6,7, every time it ask again to enter value again, but when I enter 4 it exits.
