What is the purpose of a virtual environment in software development?

A virtual environment in Python development is designed to isolate project dependencies. It allows:

• Installing necessary libraries and package versions without affecting global system settings.
• Avoiding conflicts between different projects that may require different versions of the same libraries.
• Ensuring reproducibility of development and deployment environments.

Example of creating and activating a virtual environment:

python -m venv myenv
source myenv/bin/activate  # for Linux/Mac
myenv\Scripts\activate   # for Windows

After activation, packages can be installed via pip, and they will be local to this environment.
