Simplify data analysis with Pandas DataFrames. Pandas is a Python library that enables you to work with series and tabular data, including initialization, and population. For this course, learners do not need prior experience working with Pandas, but should be familiar with Python3, and Jupyter Notebooks. Topics include the following: Define your own index for a Pandas series object; load data from a CSV (comma separated values) file, to create a Pandas DataFrame; Add and remove data from your Pandas DataFrame; Analyze a portion of your DataFrame; Examine how to reshape or reorient data, and to create a pivot table. Finally, represent multidimensional data in two-dimensional DataFrames, with multi or hierarchical indexes.

WHAT YOU WILL LEARN

  • Understand the various applications of pandas and why it is a building block in the field of data science
    Install pandas and create a pandas series
    Work with pandas series by accessing elements using the default and a custom index
    Define a pandas dataframe and describe how data can be stored and accessed in these data structures
    Initialize and populate a simple pandas dataframe
    Load data into a dataframe from a csv file
    Edit individual cells and entire rows and columns in a pandas dataframe
  • Access specific rows and columns of a pandas dataframe using the index and labels
    Access parts of a pandas dataframe based on specific conditions
    Describe the concept of a hierarchical index or multi-index and how it can be useful
    Re-orient a dataframe as a pivot table to better visualize data
    Apply a multi-index to a dataframe and reshape it using the stack and melt operations
    Work with pandas for basic tabular data manipulation
