If you’re looking to code in Ranchi or are interested in python training, Emancipation Edutech offers comprehensive courses to get you started. 1. Introduction to the Libraries What is NumPy? NumPy, short for Numerical Python, is a foundational library for scientific computing in Python. It provides support for large, multi-dimensional arrays and matrices, along with a collection of mathematical functions to operate on these arrays. What is Pandas? Pandas is an open-source data manipulation and analysis library built on top of NumPy. It provides data structures like DataFrames and Series, which are essential for handling structured data seamlessly. What is Scikit-Learn? Scikit-Learn is a powerful machine learning library for Python. It offers simple and efficient tools for data mining, data analysis, and machine learning. Built on NumPy, SciPy, and matplotlib, it is designed to interoperate with other numerical and scientific libraries in Python. 2. Purpose and Core Functionality NumPy: The Backbone of Numerical Computing NumPy is primarily used for numerical operations on arrays and matrices. Its core functionality includes: Example: Pandas: Data Manipulation Made Easy Pandas is designed for data manipulation and analysis.
