I am trying to follow the instructions in the python tutorial for AWS Cloud 9. When I did step 2 it said that python was already installed, but I went to do step 3 and the instructions are suddenly wrong.
1. In the AWS Cloud9 IDE, on the menu bar choose Run, Run Configurations, New Run Configuration.
2.On the [New] - Stopped tab, enter hello.py 5 9 for Command. In the code, 5 represents sys.argv[1], and 9 represents sys.argv[2].
3.Choose Run and compare your output.
These are the instructions. Firstly, I started a whole new IDE. When I went to do no.1 you don't even use that menu to start the "stopped tab" you have to click on the + sign next to the terminal your already running to get the "stopped tab" to pop up. So I finally figured that out, cool. Now to change the file name from "untitled" to "hello.py" i had to click on the "x" as if to close the file before it would change the name. Ok so i got that done, cool. Now i tried to run the code according to the instructions and this is what i got:
Hello, World!
The sum of 2 and 3 is 5.
Traceback (most recent call last):
File "/home/ec2-user/environment/hello.py", line 7, in <module>
sum = int(sys.argv[1]) + int(sys.argv[2])
IndexError: list index out of range
this is what its supposed to be according to the tutorial:
Hello, World!
The sum of 2 and 3 is 5.
The sum of 5 and 9 is 14.
So, clearly for whatever reason, this is not working correctly. So what am I supposed to do to get this to work correctly?
to try to solve this problem i looked in the knowledge base to see if it was there and it wasn't.

If "hello.py" has been successfully saved as a file, you can execute "hello.py 5 9" by clicking on "Run" at the top of the screen, then selecting "Run Configurations," and opening "New Run Configuration."
