Python for Data Science

Course Overview

Python for Data Science is a specialized course that focuses on leveraging the Python programming language for various aspects of data analysis, manipulation, visualization, and machine learning. Python's extensive ecosystem of libraries makes it a powerful tool for professionals aiming to extract meaningful insights from data and build predictive models.

Learn software skills with real experts, either in live classes with videos or without videos, whichever suits you best.


This course covers the fundamental Python libraries used in data science, such as NumPy for numerical computing, Pandas for data manipulation, Matplotlib and Seaborn for data visualization, and Scikit-learn for machine learning. Participants will learn to clean and preprocess data, perform exploratory data analysis, and apply statistical methods. The course also delves into machine learning techniques, enabling participants to build and evaluate predictive models using Python.


Course Objectives

The objectives of the Python for Data Science course include:

  1. Building a Foundation: Establishing a solid understanding of Python programming fundamentals and its role in data science.
  2. Data Manipulation: Learning to use Pandas for efficient data cleaning, transformation, and manipulation.
