What's wrong with my Python code?

python
#1 
number_numbers=input('How many integers do you want?')
iteration=1
sum=0
while iteration < number_numbers+1:
  rawfeed=input('Enter' number_numbers 'th')
  sum=sum+rawfeed
  iteration=iteration+1
#2

isn’t it raw_input() in python 2.x? codecademy doesn’t support 3.x yet
also try to use +=
(I might be wrong)

#3

@alex2413 is right, are you working on your own project in python3?

here:

rawfeed=input('Enter' number_numbers 'th')

you don’t concatenate the string and variable, this will certainly result in an error

What error message is the interpreter throwing at you?
