What is Pandas?
Pandas is a data analysis and data manipulation library for Python. It lets you work with tabular data as rows and columns, and while it feels as visual as using Excel, its real strength is that you can automate everything with Python code.
For example, say you have a shop's daily sales CSV file. With Pandas you can calculate total sales, group data by product, find missing values, and output clean data for a report.
- Series = one-dimensional data, like a single column
- DataFrame = two-dimensional data, like a table with rows and columns
- Index = a label that identifies each row
Info
Don't think of Pandas as just an Excel replacement. Its real value is turning the cleaning and reporting work you'd do manually in Excel into a repeatable Python workflow.
