Introduction

This tutorial is designed for beginners who are interested in learning Python programming from scratch. It will guide you through the installation and basic setup of Python and Visual Studio Code, which are essential tools for coding in Python. By the end of this guide, you will be equipped to start writing your first Python scripts.

Step 1: Understanding Python

• What is Python?

  • Python is a high-level programming language known for its simplicity and readability.
  • It is widely used for web development, data analysis, artificial intelligence, and more.

• Why Learn Python?

  • Python is beginner-friendly and has a large community, making it easier to find resources and support.
  • It is versatile and applicable in various fields, including automation, data science, and web development.

Step 2: Choosing an Integrated Development Environment (IDE)

• Recommended IDE: Visual Studio Code
  • Visual Studio Code (VS Code) is a powerful, free code editor that supports Python and many other programming languages.
  • It features extensions that enhance coding efficiency, such as syntax highlighting and code completion.

Step 3: Installing Visual Studio Code

1. Go to the Visual Studio Code website.
2. Download the installer for your operating system (Windows, macOS, or Linux).
3. Run the installer and follow the prompts to complete the installation.
4. Launch Visual Studio Code after installation.

Step 4: Installing Python

1. Visit the official Python website.
2. Download the latest version of Python suitable for your operating system.
3. Run the installer:
   • On Windows, ensure you check the box that says "Add Python to PATH."
4. Follow the installation prompts to complete the setup.

Step 5: Resolving Installation Issues

• If you encounter problems during installation:
  • Ensure that your operating system meets the minimum requirements for Python.
  • Check that you have added Python to your system's PATH variable.
  • Refer to the Python documentation or community forums for troubleshooting tips.

Step 6: Running Your First Python Script

1. Open Visual Studio Code.
2. Create a new file with the .py extension (e.g., hello.py).
3. Write a simple Python script, for example:

   print("Hello, World!")
   

4. Save the file.
5. Open the terminal in Visual Studio Code and navigate to the directory where your script is saved.
6. Run the script by typing:

   python hello.py
   

7. You should see "Hello, World!" printed in the terminal.

Conclusion

You have successfully installed Python and Visual Studio Code, and you've run your first Python script! This foundational knowledge will set you up for further exploration in Python programming. Consider exploring Python tutorials and projects to deepen your understanding. Happy coding!
