Essentially we have a object type which we will put the data into, each user's data will go into one object containing 'name, age, startdate'. then we will populate each object and store them to a list in the order they were read from the file. import csv # We need a default object for each person class Person: def __init__(self, Name, Age ...

To read a CSV file as a pandas DataFrame, you'll need to use pd.read_csv, which has sep=',' as the default..

@MahsanNourani The file pointer can be moved to anywhere in the file, file.seek(0) will move it back to the start for example and then you can re-read from start. You'll have to keep the file open obviously to perform seek operation.
