Suppress logging by cloudstorage.open() in google app engine GCS client library Python

Question

I'm using the GCS client library to write files to Google Cloud Storage in my App Engine app in Python.

Before creating a file, I need to make sure it doesn't already exist to avoid overwriting.

To do this I am checking to see if the file exists before trying to create it:

import cloudstorage as gcs

try:
    gcs_file = gcs.open(filename, 'r')
    gcs_file.close()
    return "File Exists!"
except gcs.NotFoundError as e:
    return "File Does Not Exist: " + str(e)

cloudstorage.write() is logging (either directly or indirectly) the fact that it receives a 404 error when trying to read the non-existent file. I would like to suppress this if possible.

Thanks

edit Here's what is logged:

The logging in your case was triggered by str(e). Issue was fixed in https://code.google.com/p/appengine-gcs-client/source/detail?r=172
