Pandas is a Python library that provides high-performance, easy-to-use data structures and data analysis tools. It is a fundamental building block for data analysis in Python, offering flexible and efficient ways to work with structured data.
- Data Structures: Pandas introduces two primary data structures:
- Series: A one-dimensional labeled array capable of holding any data type.
- DataFrame: A two-dimensional labeled data structure with columns that can hold different data types.
- Data Manipulation: Pandas offers a rich set of functions for data manipulation, including:
- Selection: Selecting specific rows or columns based on labels or indices.
- Filtering: Filtering data based on conditions.
- Aggregation: Calculating summary statistics (e.g., mean, median, standard deviation).
- Grouping: Grouping data by categories and performing aggregations.
- Joining and Merging: Combining data from multiple DataFrames.
- Data Cleaning: Pandas provides tools for cleaning and preparing data, such as handling missing values, removing duplicates, and converting data types.
- Data Visualization: While Pandas itself does not have extensive visualization capabilities, it integrates well with libraries like Matplotlib and Seaborn for creating informative plots.
