how to run a python file in interpreter

Question

Hi I have never used python and I am trying to run session_eval_main.py file that processes 3 text files and outputs the result. but when I try to run it in the interpreter I get the following error:

Traceback <most recent call last>: File "<stdin>", line 1, in <module> NameError: name 'session_eval_main' is not defined

Can anyone help me here.

Thanks

I think you want to be using python session_eval_main.py in a command prompt or similar... It looks like you're trying to type the name of the script into IDLE or some other editor... — Jon Clements

Just do this:

python session_eval_main.py

I'm assuming that you are referring to this script. If this assumption is true, then you can add flags:

Usage: $ python session_eval_main.py --qrel_file=qrels --mapping_file=topics_sessions --run_file=runs --dup_file=dups --per_session=0 --cutoff=10 --write_to_file=0

If you need help with what each flag does, run this:

$ python session_eval_main.py --help

make sure you open python and not IDLE. IDLE is a document editor. you want to open the python command line. To use the code jh314 posted above, simply open command prompt and enter that in.
Also, make sure that session_eval_main.py is in your current directory when you run it.
