Q:

What user do python scripts run as in windows? 

I'm trying to have python delete some directories and I get access errors on them.  I think its that the python user account doesn't have rights? 
WindowsError: [Error 5] Access is denied: 'path'

is what I get when I run the script. 
I've tried  
shutil.rmtree  
os.remove  
os.rmdir

they all return the same error. 

A:

We've had issues removing files and directories on Windows, even if we had just copied them, if they were set to 'readonly'.  shutil.rmtree() offers you sort of exception handlers to handle this situation.  You call it and provide an exception handler like this:
import errno, os, stat, shutil

def handleRemoveReadonly(func, path, exc):
  excvalue = exc[1]
  if func in (os.rmdir, os.remove) and excvalue.errno == errno. EACCES:
      os.chmod(path, stat. S_IRWXU| stat. S_IRWXG| stat. S_IRWXO) # 0777
      func(path)
  else:
      raise

shutil.rmtree(filename, ignore_errors=False, onerror=handleRemoveReadonly)

You might want to try that.

I've never used Python, but I would assume it runs as whatever user executes the script.
