python virtual environment

A Python virtual environment is a self-contained directory that contains a specific version of Python and its dependencies. It allows developers to isolate and manage different sets of dependencies for different projects, without interfering with each other. Virtual environments are particularly useful when working on multiple projects with different requirements, or when collaborating with other developers who may have different versions of Python or dependencies installed on their machines. Virtual environments can be created using command-line tools such as virtualenv or venv, or using integrated development environments (IDEs) like PyCharm or Visual Studio Code. Once a virtual environment is activated, any packages installed or scripts executed will use the dependencies within that environment, rather than the global Python installation.
