There are test codes written to change the tracker file content and see whether it works or not. If you just want to create a tracker file then please avoid running the code snippet.

Run this right after creating the profile-reading-tracker file



In [52]:

    
import pandas as pd

This is just a test to check whether editing a row and updating it in the file and reading it back works or not



In [58]:

    
data = pd.read_csv('profile-reading-tracker')
data.head()
