High:
Start off with a blank array then get the user to enter numbers until they enter nothing.
Note: You will have use input without casting to an int as you need to check if they entered a blank string. You can always cast the number later (see below):
number=input("Enter an number of blank to finish:"
if number="": #do something
number=int(number) # turn number into an integer after we check for blank.
Numbers= []
To add an item to an array do:
Numbers.append(5)
