R and Python Cheat Sheets 05/01/2016
In winter of 2015, I was looking for simple, fast, professional looking R and Python cheat sheets since my work involved switching back and forth between multiple languages (R, Python, Java) as well as other non-programming/data science duties.
However, many online cheatsheets that I found were either too lengthy or too slow to scan or too boring/uncolorful. Therefore, we have created R and Python cheat sheets. We hope these cheatsheets are not only useful for ourselves, but for other R and Python users as well.

By now, you’ll already know the Pandas library is one of the most preferred tools for data manipulation and analysis, and you’ll have explored the fast, flexible, and expressive Pandas data structures, maybe with the help of DataCamp’s Pandas Basics cheat sheet.
Yet, there is still much functionality that is built into this package to explore, especially when you get hands-on with the data: you’ll need to reshape or rearrange your data, iterate over DataFrames, visualize your data, and much more. And this might be even more difficult than “just” mastering the basics.
That’s why today’s post introduces a new, more advanced Pandas cheat sheet.
It’s a quick guide through the functionalities that Pandas can offer you when you get into more advanced data wrangling with Python.
