I guess it's special to me because of the struggle it took to get here. My degree isn't in Computer Science, but I really wanted to get into programming and I thought it'd be too difficult to get my foot in the door. But the job I've just got is at a tier 1 investment bank as a Developer, so now I'll get to do something I enjoy for a job, get paid really well for it, and live/work in a beautiful part of London. Not a bad place to start!

Love the tutorials Corey they help so much in learning Python. Just thought I would update this video because the syntax is off around 8:00. The context manager "with open('new_names', 'w') as new_file:" will return a CSV file with a blank row in-between each row. The quick fix is to add "with open('new_names', 'w', newline='') as new_file:" and the issue goes away.

First of all Corey, I will like to say that you're an amazing teaching. You've inspired lots of people especially someone like me that is pretty new to Python. Your videos are awesome. Just keep up the good work we really do appreciate you. Thank you! With that been said, Corey, I have been searching and googling almost everywhere like stack overflow and many other python communities to see if I can at least find maybe an examples on how to work on or handle large files in python -- files ranging from 100 GB and up. Unfortunately, I haven't seen anything that actually explains the concept clear enough. So, I was wondering maybe if possible if you will consider making a video just for that purpose. Basically, the program should be able to read, chunk and write the file(s) or segments into a folder based on numbers of lines or size specified by the user. Please I will really appreciate it if you can help. Thanks in advance!

Hi Nikki, I haven't really tried this yet so I don't clearly understand but, I wanted to know why this happens when writing the data. In the video the newline parameter was not passed but did not skip any lines. In what situation would it be skipped and what is the reasoning?
@nikluz38075 жыл бұрын
tinnick great question. I am actually not 100% sure to be perfectly honest as I am not an expert. The only logical explanation I can come up with is that the csv module has been updated since the video and the newline parameter was introduced in one of the updates. Modules are constantly being updated, as well as their default behavior. It’s just part of programming. Sometimes this can even break your already perfect application, leaving you to read through updated documentation to see what has changed. I hope this helps you.
