Working with Pandas DataFrames in Python Introduction to Pandas and DataFrames Pandas is a powerful library in Python for data manipulation and analysis. It provides data structures and functions to efficiently handle structured data, including tabular data such as spreadsheets and SQL tables. At the heart of Pandas lies the DataFrame, which is a two-dimensional labeled data structure with columns of potentially different types. DataFrames are similar to Excel spreadsheets or tables in relational databases, where each column represents a variable and each row represents an observation.
