Passing a variable to a query in google-drive-api files().list function

I'm trying to create a function which takes in a directory name as a parameter and returns the ID of the directory. The ultimate goal is to list the files in said directory using the returned file ID, however I can't seem to figure out the syntax for passing the directory name in as a variable.

I can only manage to do something of the following, where I need to explicitly type in the name of the directory. Please note that I am using v3 of the google drive api.

def get_folder_id():

    folder_ID = ""

    while True:
        response = drive_service.files().list(
            q="name='folder1'", fields="nextPageToken, files(id,name)").execute()

        files = response.get('files', [])

        for item in files:
            print ("Found file: %s, %s" % (item['name'], item['id']))
            folder_ID = item['id']

        page_token = response.get('nextPageToken', None)

        if page_token == None:
            break

    return folder_ID

How can I pass the folder name as a parameter and still include it in the q query?

I've tried variants such as:

response = drive_service.files().list(
            q='"name="' + "'" + f_name + "'" + '"', fields="nextPageToken, files(id,name)").execute()

In an attempt to include the single quotes around the request, but this doesn't work either

• You want to retrieve the folder ID from the folder name using Drive API v3 with Python.

If my understanding is correct, how about using the following search query? Please modify as follows.

From:

q='"name="' + "'" + f_name + "'" + '"'

To:

q="name='" + f_name + "' and mimeType='application/vnd.google-apps.folder' and trashed=false"

• In this modification, the search query was modified.
  • mimeType='application/vnd.google-apps.folder' means the folder.
  • trashed=false means files outside of the trash box.

By above search query, the folders which has the folder name of f_name are retrieved.

Reference:

• Search for Files
