John Granieri: Pandas - a bit more in depth

Pandas is a very convenient, yet powerful, data handling and analysis library written in Python and Cython. I'll review the basic functions and then spend the majority of my time on the intermediate to advanced features of the library, along with some of the related tools for handling larger scale data analysis problems with Pandas.

John Granieri works @ SIG, a proprietary trading firm located just outside Philadelphia, PA, working on research computing for automated trading systems. He holds a Ph.D. in Computer Science from University of Pennsylvania where he studied and worked on interactive 3D animation systems. He's been using Python in various forms and for various roles in automation for almost 20 years.

    This would be great but unfortunately I have a work commitment. Will you be posting notes? If so, where?

    I wasn't able to attend this event, but I enjoy Pandas, and use it with iPython Notebooks and Python.

    Most of my tasks involve manipulation of csv or fixed length text files, into DataFrames, then filtering/exporting the data into Excel for further analysis and filtering.

    I've also incorporated writing the data to MongoDB so I can use MongoDB queries and workflows to analyze the data.

    I was sorry to miss this presentation. Are there any notes from the presentation?

    Hey everyone, for those looking for notes from the presentation - John will be sending me a .zip of the notebooks and data from his talk. I'll post a link here and send it around on the mailing list as well.

    John was a great speaker and came very well prepared--I appreciated his clear, informative demo. A great presentation all around.

    Very interesting tutorial and examples of how Pandas can be used for analytics to build upon other key numeric and scientific packages and to handle data frame processing that one would otherwise do in R.

    Not the greatest speaker, but otherwise a useful display of Pandas capabilities with a lot of good tips on how to get things done.

    Wish I could have made it, but I'm out of town.
