About:
Virtualenv is a command-line tool that creates lightweight, self-contained Python environments. It isolates dependencies for different projects, preventing version conflicts between packages. This allows developers to manage project-specific libraries without affecting the global Python installation.
Key Features:
  • Isolated dependency management
  • Support for multiple Python versions
  • Extensible via plugins
  • Fast environment creation
  • Consistent environments across systems
Use Cases:
  • Developing Python applications with specific dependency requirements
  • Testing packages against different Python versions
  • Maintaining separate environments for production and development
Alternatives:
  • venv – Built-in Python module, more limited features but no installation required
  • conda – Broader ecosystem management including non-Python dependencies, heavier weight
