How to read all of the files in a specific directory in google drive using python?

Question

I'm trying to go through all of the files in a folder to read and analyze them in python. There are a large number of these files and I would like to iterate through each file in the folder without having to hardcode the file names in.

drive = GoogleDrive(gauth)
file_list = drive.ListFile({'q': "'1fasSmc7insM4cQOoCik0vmEvYLN6Z5XZ' in parents and trashed=false"}).GetList()

Answer 1

To search in the root directory, you can use:

file_list = drive.ListFile({'q': "'root' in parents and trashed=false"}).GetList()

This gives you a list of all files in the root.

To have a list of all files in a sub-directory, you can replace 'root' with the folder id.

folder_id = '****'
file_list = drive.ListFile({'q': "'folder_id' in parents and trashed=false"}).GetList()

Answer 2

I have a code that I am actively using.

folder_id = '********'
file_list = drive.ListFile({'q': "'{}' in parents and trashed=false".format(folder_id)}).GetList()
