Python Virtual Environment

Introduction
In project management, managing dependencies for different project and environment is a difficult task.

Python virtual environment simplifies dependency management and project isolation.

Here, we try to cover about python virtual environment, its advantages and setup.

What is Python virtual environment?
It is a self container directory with set of libraries and dependencies specific to project.

Container

It helps to isolate project dependencies from different set of projects in environment which avoids confusion and also enhances efficiency.

Key Advantages

  • Dependency Isolation: Ensures each project has isolated set of libraries

-Easy Management: User can load each project with only required set of dependencies which simplifies installation and project setup process.

Laodingggg

  • Reproducible: It ensures exact dependencies are used wherever project setup is done.

  • Portable: can be easily shared across different system.

Setup and Commands

  • Creation: Use pip install virtualenv command in terminal

venv

  • Activation: Use commands virtualenv <directory> and Scripts\Activate

Creation

  • Installation: install required packages using pip

packages

  • Deactivation: Use command Scripts\deactivate to deactivate venv

Conclusion
It is an useful concept in terms of managing dependencies, different environment and projects.

By isolation of dependencies, maintaining projects becomes easier particularly to developers who work in multiple projects and also testers who develops and execute different type of test suite which requires different packages based on environment and test phase.
