executing scripts via command line

Nov 21st, 2008

Hello!

I'm trying to execute a simple script in the command line, and for some reason, it's not working. Shouldn't it be as simple as this?

python myscript.py

And yet when I try that, I get "Syntax Error: invalid syntax"

I've googled around, read through the docs--I have a feeling that this is probably something silly/small. Any help?

Thanks!

The syntax error is somewhere in your script. Can you post the script (or attach it) ?

I checked controller.py, and got an error message:

exec "from " + sys.argv[1] + " import *"
IndexError: list index out of range

Here's the script:

import sys
from tichu import *
exec "from " + sys.argv[1] + " import *"

def exampleFeatureFunction(hand):
    fv=[0, 0, 0]
    fv[0]=1
    if (hand[DRAGON]>0):
        fv[1]=1.0
    if (hand[PHOENIX]>0):
        fv[2]=1.0
    return fv

def alwaysSayNo(hand, model):
    return False

if __name__=="__main__":
    if (sys.argv[3]=="baseline"):
        evaluate(sys.argv[2], None, alwaysSayNo)
    elif (sys.argv[3]):
        evaluate(sys.argv[2], sys.argv[3], eval(sys.argv[4]))

There are other files (the "tichu" file it's importing from); let me know if you need to see more.
