In the real-world, data is anything but clean, which is why Python libraries like Pandas are so valuable.If data manipulation is setting your data analysis workflow behind then this course is the key to taking your power back.Own your data, don't let your data own you!When data manipulation and preparation accounts for up to 80% of your work as a data scientist, learning data munging techniques that take raw data to a final product for analysis as efficiently as possible is essential for success.Data analysis with Python library Pandas makes it easier for you to achieve better results, increase your productivity, spend more time problem-solving and less time data-wrangling, and communicate your insights more effectively.This course prepares you to do just that!With Pandas DataFrame, prepare to learn advanced data manipulation, preparation, sorting, blending, and data cleaning approaches to turn chaotic bits of data into a final pre-analysis product. This is exactly why Pandas is the most popular Python library in data science and why data scientists at Google, Facebook, JP Morgan, and nearly every other major company that analyzes data use Pandas.If you want to learn how to efficiently utilize Pandas to manipulate, transform, pivot, stack, merge and aggregate your data for preparation of visualization, statistical analysis, or machine learning, then this course is for you.Here's what you can expect when you enrolled with your instructor, Ph.D. Samuel Hinton:Learn common and advanced Pandas data manipulation techniques to take raw data to a final product for analysis as efficiently as possible.Achieve better results by spending more time problem-solving and less time data-wrangling.Learn how to shape and manipulate data to make statistical analysis and machine learning as simple as possible.Utilize the latest version of Python and the industry-standard Pandas library.Performing data analysis with Python's Pandas library can help you do a lot, but it does have its downsides. And this course helps you beat them head-on:1. Pandas has a steep learning curve: As you dive deeper into the Pandas library, the learning slope becomes steeper and steeper. This course guides beginners and intermediate users smoothly into every aspect of Pandas.2. Inadequate documentation: Without proper documentation, it's difficult to learn a new library. When it comes to advanced functions, Pandas documentation is rarely helpful. This course helps you grasp advanced Pandas techniques easily and saves you time in searching for help.After this course, you will feel comfortable delving into complex and heterogeneous datasets knowing with absolute confidence that you can produce a useful result for the next stage of data analysis.Here's a closer look at the curriculum:Loading and creating Pandas DataFramesDisplaying your data with basic plots, and 1D, 2D and multidimensional visualizations.Performing basic DataFrame manipulations: indexing, labeling, ordering slicing, filtering and more.Performing advanced Pandas DataFrame manipulations: multiIndexing, stacking, hierarchical indexing, pivoting, melting and more.Carrying out DataFrame grouping: aggregation, imputation, and more.Mastering time series manipulations: reindexing, resampling, rolling functions, method chaining and filtering, and more.Merging Pandas DataFramesLastly, this course is packed with a cheatsheet and practical exercises that are based on real-life examples. So not only will you learn the theory, but you will also get some hands-on practice with Pandas too.
