Pandas

Pandas is an open-source library for data manipulation and analysis in Python. It was created by Wes McKinney in 2008 and was initially released in 2011. Pandas is designed to handle tabular, heterogeneous, and time-series data, making it a powerful tool for data wrangling, cleaning, transformation, and analysis.

Pandas provides two primary data structures for data manipulation: Series and DataFrame. A Series is a one-dimensional labeled array that can hold any data type. A DataFrame, on the other hand, is a two-dimensional labeled data structure, consisting of rows and columns, similar to a spreadsheet or a SQL table.

One of the key features of Pandas is its ability to handle missing or incomplete data. Pandas provides several methods for handling missing data, such as filling in missing values with interpolation, dropping missing values, or replacing missing values with a default value.

Pandas also provides a rich set of functions for data manipulation and analysis, such as grouping data, applying functions to data, merging data, and pivoting data. These functions can be used to perform a wide range of tasks, from basic data cleaning and filtering to more complex data transformations and analysis.

Pandas is widely used in data science, machine learning, and data analysis. It has become the de facto standard for data manipulation in Python, and it is often used in conjunction with other Python libraries, such as NumPy, SciPy, and Matplotlib.

Some of the key features of Pandas include:

1. Data cleaning and transformation: Pandas provides a wide range of functions for cleaning and transforming data, such as handling missing values, converting data types, and applying functions to data.
