If you want to print the list after each append, then print the list 
after each append:

def getNumbers(num):
     myList=[]
     for number in range(0, num, 2):
         myList.append(number)
         print mylist


If you want to print the list once, at the end, then print it once, at 
the end, *outside* the loop:

def getNumbers(num):
     myList=[]
     for number in range(0, num, 2):
         myList.append(number)
     print mylist
