executing scripts via command line

[payne_99]

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) ?

Ah, I see. So the actual command I was trying to execute was

python controller.py

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

Traceback (most recent call last):
File "C:\Users\p\controller.py", line 3, in <module>
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.

Your problem is that sys.argv is what you supply on the command line after starting the script. So you would go

python mycode.py arg1 arg2

For yours to work you need at least 2 arguments for there to be sys.argv[1]
