how to read data from google drive using Colaboratory (google)

问题

I'm new to Colaboratory and would like setup a small project which is stored on my google drive. On my google drive, I create a folder 'TheProject', where I created two folders: 'code' and 'data'. I the folder 'code' I created a new colab notebook and I have several data sets in 'data' folder.

QUESTION

How to read data into colab notebook from a folder on the google drive? For example:

data = pd.read_excel('SOME_PATH/TheProject/data/my_data.xlsx')

where SOME_PATH should indicate how to get to the main folder 'TheProject' and read data from 'data' folder.

Right click on your file on Google Drive and get its sharable link. from that link you'll extract the file id.

! pip install pydrive
# these classes allow you to request the Google drive API
from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive 
from google.colab import auth 
from oauth2client.client import GoogleCredentials

# 1. Authenticate and create the PyDrive client.
auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)
file_id = '<your_file_id>'
downloaded = drive.CreateFile({'id': file_id})
# allows you to temporarily load your file in the notebook VM

# assume the file is called file.csv and it's located at the root of your drive
downloaded.GetContentFile('file.csv')

Once you hit these commands you will be prompted a link that asks you to grant permission to Google Drive. It'll give you a token that you must type in a text box.

Now you're ready to load your file:

data = pd.read_csv('file.csv')
