How to upload csv file (and use it) from google drive into google colaboratory

Question

Wanted to try out python, and google colaboratory seemed the easiest option.I have some files in my google drive, and wanted to upload them into google colaboratory. so here is the code that i am using:

!pip install -U -q PyDrive

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)

# 2. Create & upload a file text file.
uploaded = drive.CreateFile({'xyz.csv': 'C:/Users/abc/Google Drive/def/xyz.csv'})
uploaded.Upload()
print('Uploaded file with title {}'.format(uploaded.get('title')))

import pandas as pd
xyz = pd.read_csv('Untitled.csv')

Basically, for user "abc", i wanted to upload the file xyz.csv from the folder "def". I can upload the file, but when i ask for the title it says the title is "Untitled". when i ask for the Id of the file that was uploaded, it changes everytime, so i can not use the Id.

How do i read the file??? and set a proper file name???

xyz = pd.read_csv('Untitled.csv') doesnt work
xyz = pd.read_csv('Untitled') doesnt work
xyz = pd.read_csv('xyz.csv') doesnt work

Here are some other links that i found..

To read a csv file from my google drive into colaboratory, I needed to do the following steps:

1) I first needed to authorize colaboratory to access my google drive with PyDrive. I used their code example for that. (pasted below)

2) I also needed to log into my drive.google.com to find the target id of the file i wanted to download. I found this by right clicking on the file and copying the shared link for the ID. The id looks something like this: '1BH-rffqv_1auzO7tdubfaOwXzf278vJK'

3) Then I ran downloaded.GetContentFile('myName.csv') - putting in the name i wanted (in your case it is xyz.csv)

This seems to work for me!

I used the code they provided in their example:

# Code to read csv file into colaboratory:
!pip install -U -q PyDrive
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)

#2. Get the file
downloaded = drive.CreateFile({'id':'1BH-rffqv_1auzO7tdubfaOwXzf278vJK'}) # replace the id with id of file you want to access
downloaded.GetContentFile('xyz.csv')  

#3. Read file as panda dataframe
import pandas as pd
xyz = pd.read_csv('xyz.csv')
