I'm having a tough time using a subprocess.call to run s3cmd

here is where I'm stuck:

subprocess.call(["python", "s3cmd","sync", "C:\filepath", "S3://bucketpath"])


other lines have worked fine such as:

subprocess.call(["python", "s3cmd", "ls" "S3://bucktpath"])

Thanks for your help!!

I'm really stuck on this.
