check whether a folder exists with name using python

How to check whether a folder exists in google drive with name using python?

I have tried with the following code:

import requests
import json

access_token = 'token'

url = 'https://www.googleapis.com/drive/v3/files'

headers = {
'Authorization': 'Bearer' + access_token
 }

response = requests.get(url, headers=headers)
print(response.text)

You may see this sample code on how to check if destination folder exists and return its ID.

def get_folder_id(drive, parent_folder_id, folder_name):
    """ 
        Check if destination folder exists and return it's ID
    """

    # Auto-iterate through all files in the parent folder.
    file_list = GoogleDriveFileList()
    try:
        file_list = drive.ListFile(
            {'q': "'{0}' in parents and trashed=false".format(parent_folder_id)}
        ).GetList()
    # Exit if the parent folder doesn't exist
    except googleapiclient.errors.HttpError as err:
        # Parse error message
        message = ast.literal_eval(err.content)['error']['message']
        if message == 'File not found: ':
            print(message + folder_name)
            exit(1)
        # Exit with stacktrace in case of other error
        else:
            raise

    # Find the the destination folder in the parent folder's files
    for file1 in file_list:
        if file1['title'] == folder_name:
            print('title: %s, id: %s' % (file1['title'], file1['id']))
            return file1['id']

Also from this tutorial, you can check if folder exists and if not, then create one with the given name.

  • You want to know whether a folder is existing in Google Drive using the folder name.
  • You want to achieve it using the access token and requests.get().

If my understanding is correct, how about this modification? Please think of this as just one of several answers.

Modification points:

  • You can search the folder using the query for filtering the file of drive.files.list.
    • In your case, the query is as follows.
      • name='filename' and mimeType='application/vnd.google-apps.folder'
    • If you don't want to search in the trash box, please add and trashed=false to the query.
  • In order to confirm whether the folder is existing, in this case, it checks the property of files. This property is an array. If the folder is existing, the array has elements.

Modified script:

import requests
import json

foldername = '#####' # Put folder name here.

access_token = 'token'
url = 'https://www.googleapis.com/drive/v3/files'
headers = {'Authorization': 'Bearer ' + access_token}  # Modified
query = {'q': "name='" + foldername + "' and mimeType='application/vnd.google-apps.folder'"}  # Added
response = requests.get(url, headers=headers, params=query)  # Modified
obj = response.json()  # Added
if obj['files']:  # Added
    print('Existing.')  # Folder is existing.
else:
    print('Not existing.')  # Folder is not existing.

If I misunderstood your question, please tell me. I would like to modify it.
