User input for a recursive function

[SpartanIE]

I'm trying to design a function that accepts a list of numbers as an argument. I can get the program working when i put a list into the programme but I can't figure out how to allow a user to enter a series. What i've got so far is below. Any help would be appreciated.

def main():

    list= [2, 4, 6, 8, 9, 12, 6, 10, 9, 6, 7 ]   

    my_sum = sum(list)

    # Display the sum
    print "The sum of numbers in the list is", my_sum

def sum(list):
    if list == []:
        return 0
     else:
        return list [0] + sum (list[1:])


main()

Your sum is correct, just do not use sum as function name. You just need to make user input function, look code snippets section for examples.

Avoid using names like list and sum since they are internal to Python. Something like this will work:

mylist = []
prompt = "%d) enter an integer (-99 to stop): "
for k in range(1000):
    x = int(raw_input(prompt % (k+1)))
    if x == -99:
        break
    mylist.append(x)

print(mylist)  # test

'''
1) enter an integer (-99 to stop): 4
2) enter an integer (-99 to stop): 66
3) enter an integer (-99 to stop): 7
4) enter an integer (-99 to stop): 12
5) enter an integer (-99 to stop): -99
[4, 66, 7, 12]

'''

Sorry, the code areas are still rather goofy in the 'new improved' DaniWeb

For fun here is recursive function producing sum of numbers without remembering the numbers:

def my_sum():
    n = raw_input('Next number or empty to finish: ')
    return (float(n) + my_sum()) if n else 0

s = my_sum()
print "The sum of numbers is", s
