How to read CSV files with Python #1 - Without using python libraries

CSVs are plain text files that use specific structures to store data. Even though they are very simple to read, sometimes dealing with CSVs can be annoying and full of errors.

In this tutorial, we are going to learn about reading CSV files using Python without the use of any libraries. We are also going to look at some advantages and disadvantages of the method.

Just started learning python recently, this is my first programming language. This video helped me a lot, thanks :) Subscribed and will keep following, cheers!

Cool stuff, although you should have closed the file with "csv_file.close()" because that leaves the handle open. Other option would have been to use the "with" statement as context manager.

Hi Lenin, regarding data cleaning > lets say we have a csv file and we are using pandas and dataframes to read the data in this csv file and then clean it. So the columns have currency amounts as $120, 000 and so on in one column. Also some fields have $0 where there is no amount entered. How do i clean these two things(the prefix $ from each amount and the useless $0 figures) from the entire csv file? am trying out with dataframe.replace and dataframe.drop kind of methods but getting mixed results. What would be the best way to do this in your own work experience? hope you will take the time to answer this.. thanks... madhur

Your code does not work if there is a comma in the text itself other the than comma that separates columns as .split(', ') will consider comma in the text as delimiter too.
