Working with Pandas DataFrame
A DataFrame is the core data structure in Pandas, providing a two-dimensional table for storing data. It is similar to a spreadsheet or SQL table and consists of rows and columns, where each column can be of a different data type (e.g., integer, float, string).DataFrames are extremely versatile and essential for data manipulation and analysis tasks. You can create, manipulate, and analyze data stored in DataFrames with a variety of operations that are both powerful and easy to use.

Working with Text Data in Pandas
Text data, also known as string data, is one of the most common data types encountered in data analysis. In Pandas, strings are represented as object dtype, which is typically used for text or mixed types. Pandas provides a variety of functions to efficiently handle and manipulate text data, whether you're cleaning, transforming, or extracting meaningful information.This chapter will guide you through the various tools and techniques that Pandas provides for working with text data. We’ll explore string manipulation methods, cleaning operations, and more advanced use cases like extracting specific patterns using regular expressions.
