In this video you will learn the basics of how to use pandas in python for data science. Rob Mulla, kaggle grandmaster, will walk through the tutorial in a kaggle notebook. This pandas python tutorial for data science is great for anyone new to learning this technology. Pandas is a MUST for anyone getting into data science with python. Python is the #1 coding language for data science and has been growing over the years as an essential tool, with Pandas being the main data wrangling module. In this video we discuss the basics of how to use pandas including...

Honestly I have no idea why it's working like that! I guess it has to be something with Excel formatting...

I watched the whole video and I am so amazed at how easy is to do data analysis nowadays. I am the generation that used: Lotus to Excel, due to their limitation we needed to combine Statistical Packages(R, SAS), Graphing(Grapher), and 3D surface mapping (Surffer) plus Visual Basic. Now I have decided to learn Python plus others to go back to some old data for recalibration that was impossible deal with due to memory overloading. Panda is very powerful. Thank you very much for sharing your knowledge.

@robmulla Жыл бұрын

I'm not sure, if "thing" is a string it will show as "object" if you count on it it will produce a number integer.. but I'm not sure exactly what you are asking.

For the last few weeks I've been struggling to learn how to do with Python what I do in 10 minutes with Excel. And a few months ago I spent half a day figuring out most of the steps to do the same analysis in Matlab. Dataframes are ridiculously difficult to deal with I'm learning it because several colleagues said that if I'm looking for a new systems engineering job, I should know Python. Numpy is easy. Pandas dataframes are obscure and clunky.

@robmulla Жыл бұрын

Interesting to hear you actually find numpy easier to work with than dataframes. I find the opposite because dataframes have an index and column names. It might just take some time and then it will click for you, or maybe you will find something else that works better for your use case. Hope the video was helpful and good luck on your journey.

Yes! It's actually really easy. Just click the three dots in the top right corner of the kaggle notebook and then click "download code" you then can open it in google colab. You would also need to download and link the data. Why do you prefer colab over a kaggle notebook? They are very similar.

@robmulla 2 жыл бұрын

Hey Carolina. This message usually comes up when you are trying to edit a subset of a previously defined dataframe. The best fix is to add `.copy()` after subsetting and renaming a dataframe. So before you might have: df_small = df.query('thing > 10') Change to: df_small = df.query('thing > 10').copy()
