Understanding the Basics of DataFrames and String Manipulation in Pandas Pandas is a powerful library used for data manipulation and analysis in Python. It provides data structures and functions designed to make working with structured data (like tabular data) as easy as possible. One common use case in pandas involves working with DataFrames, which are two-dimensional labeled data structures with columns of potentially different types. Each column can be thought of as a string that represents the name of the column.
