To facilitate a well-organized development environment, the creation of virtual environments is highly recommended. Virtual environments enable the isolation of Python projects, preventing potential conflicts between different project dependencies. The ‘venv’ module, included in the Python standard library, can be employed to create virtual environments. To establish a virtual environment, navigate to the desired project directory in the command prompt and execute the command ‘python -m venv venv’. This creates a virtual environment named ‘venv’ in the project directory.

To activate the virtual environment, the command ‘.\venv\Scripts\activate’ should be executed. Once activated, the command prompt reflects the active virtual environment in its prompt, providing a clear indication of the isolated development environment. To install packages within the virtual environment, ‘pip’ can be utilized as usual, ensuring that dependencies are contained within the project’s scope.

Furthermore, an Integrated Development Environment (IDE) can significantly enhance the development experience. There are several IDEs compatible with Python, and one popular choice is Visual Studio Code (VSCode). To integrate Python with VSCode, the Python extension must be installed. This extension equips VSCode with features like intelligent code completion, debugging capabilities, and integrated support for virtual environments.

After installing VSCode, navigate to the Extensions view by clicking on the Extensions icon in the Activity Bar on the side of the window. Search for ‘Python’ in the Extensions view search box, locate the official Python extension, and install it. Once installed, VSCode is ready for Python development.

In summary, the installation and configuration of Python 3 on Windows 10 involve downloading the latest Python version from the official website, running the installer, ensuring Python is added to the system’s PATH, and customizing the installation if necessary. Verification of a successful installation can be done through the command prompt. Additionally, configuring the development environment includes updating ‘pip’, creating virtual environments with ‘venv’, activating virtual environments, and integrating with an IDE like Visual Studio Code for a comprehensive and efficient Python development setup. This meticulous approach ensures a robust foundation for coding in Python on a Windows 10 system.
