Answer 1

Considering: I just started learning Python

I'd suggest something like this, which handle input errors:

inflow = raw_input("Type numbers (e.g. '1 3 5') ") #in py3 input()
#inflow = '1 2 34 5'

try:

    result = sum(nums)
    print(result)

except ValueError:
    print("Not a valid input")
