A Gentle Introduction to Pandas Data Analysis (on Kaggle)

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...

Thanks for the video, I've learnt a lot! I tried casting different dtypes on the imported Excel spreadsheet columns and found out an interesting issue, when I summed up the numbers in the same column with float64 and int64 dtypes, I got different results (no decimal points involved). Honestly I have no idea why it's working like that! I guess it has to be something with Excel formatting...

[@PaquiCamus]

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]

Glad the video showed you something new. Pandas is a great skill to master and can be really powerful for doing things that aren’t possible to do in excel with large datasets.

Hello, I saw one of your post in the youtube forum saying that your Timestamps didn’t worked out properly, I see now that it works. Did you do anything for it to work, any report sent to youtube ? Did the Timestamp worked after you hit the 1000 subscribers or the problem was there before ?

Hey! Yes. that was really frustrating. I didn't do anything special. It took a few months but then started working. I hope you get it figured out too.

Hi folks Does anyone know what keyboard he is using? Thanks in advance

[@wiscgaloot]

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]

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.

Hi - why is the series of 'thing' in mydf dataframe an object dtype, but the 'count' is an int64 dtype? Why is 'thing' not a 'string' dtype?

[@robmulla]

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.

[@jonesPossibly]

@@robmulla hiya - thanks for the reply - at kzbin.info/www/bejne/lXbFYaiqfreXodk you can see that the series containing stings has a dtype of object, whereas the series containing the integers has a dtype of int64. I was just wondering why its object and not string?

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]

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()
