About Course

This course is designed to provide you with the essential tools and skills to perform data analysis using Python in the powerful and versatile environment of Visual Studio Code (VS Code). Through hands-on learning and real-world examples, you will gain a deep understanding of key Python libraries such as Pandas, NumPy, Matplotlib, and Seaborn for data manipulation, visualization, and statistical analysis.

You will begin by setting up and customizing your VS Code environment for optimal data analysis, then move on to explore how to import, clean, and preprocess datasets. As you progress, you will learn techniques for data exploration, data transformation, and feature engineering. The course also covers visualizing data with informative plots and graphs, as well as conducting statistical analysis to draw meaningful insights.

By the end of this course, you will be equipped with the skills to handle real-world datasets, perform robust data analysis, and build data-driven applications using Python within the VS Code environment. Whether you’re looking to advance your data science career or gain deeper insights into your data, this course will provide the foundation you need to succeed.

Key Topics Covered:

  • Introduction to VS Code and Python setup
  • Data import and preprocessing using Pandas
  • NumPy for numerical data manipulation
  • Data visualization with Matplotlib and Seaborn
  • Statistical analysis and hypothesis testing
  • Handling missing data and data cleaning techniques
  • Best practices for Python code in VS Code for data analysis
