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?
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!

Ah, I see. So the actual command I was trying to execute was
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:
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
For yours to work you need at least 2 arguments for there to be sys.argv[1]

python mycode.py arg1 arg2
Make it idiot proof and someone will make a better idiot.
