NumPy is an amazing scientific computing library that is used by numerous other Python Data Science libraries. NumPy contains many mathematical, array and string functions that are extremely useful. Along with all the basic math functions you'll also find them for Linear Algebra, Statistics, Simulation, etc.

I cover most everything you'll learn by reading the API here. Next I'll cover SciPy, Pandas, StatsModels, MatPlotLib, Seaborn, Plotly, Scikit-learn, TensorFlow, PyTorch, Keras, Scrapy, Linear Algebra, Calculus and more. CLICK THE NOTIFICATION BELL

You're better than my university professors Derek!
Thanks for taking lot of efforts and sharing knowledge ☺️

@derekbanas

Thank you for the nice compliment :) It is my pleasure to help

VidTutorAssistant (GPT-4)

I'm really glad to hear that you're finding the videos helpful, @ArunKumar-rn7ww! Appreciate your kind words. I enjoy sharing these tutorials and it gives me joy to know that it's beneficial to others. Stick around for upcoming videos where we'll be diving deeper into Python libraries. And remember, programming is a journey, so keep learning and coding!

31:23 I've got a problem here. The comand returns error " 'DataFrame' object has no attribute 'to_numpy' ". What should I do?
Actually, how come derek writes only the name of the file without its path?

@derekbanas

If you imported pandas you shouldn't get that error. Maybe try pip install --upgrade pandas
I don't use a path because all my files are in the same directory. tell me if that doesn't help

VidTutorAssistant (GPT-4)

Hi @andrewignatov323, thanks for reaching out! You're seeing this error because the function 'to_numpy' isn't recognized on your DataFrame object. This could be due to having an older version of Pandas that doesn't have this function. You might want to try updating your Pandas library. Use `pip install pandas --upgrade` command in your terminal to update.

Regarding your second question, the reason that I'm only using the filename without its path is because the file is located in the same directory as the Python script we're running, so there's no need to include the entire path. If your file is in a different directory, you would need to specify the complete path to that file. Remember, file paths can be absolute (from the root directory) or relative to the current working directory.

Keep up the great work with your Python learning journey! 😊 Let me know if you have any more questions!
