For loop in my python program not running

Question

I am coding something were you enter a main number, then a list of numbers again. It is supposed to see if any two numbers in the list add up the the main number. I am using for() loops to compare the numbers, but they don't seem to be running.

IsDone = None
AddingList = []
MainNum = input('Enter a number:    ')
Cnt = 0

while IsDone != 'yes':
    NewItem = int(input('Enter a number:    '))
    AddingList.append(NewItem)
    IsDone = input('Are you done yet?   ')

for i in range(len(AddingList)):
    for a in range(len(AddingList)):
        if int(AddingList[i]) + int(AddingList[a]) == MainNum:
            print(AddingList[i])
            print(AddingList[a])
