virtual environment

python3 -m venv venv source venv/bin/activate


venv is a module in Python used for creating virtual environments. A virtual environment is an isolated space where Python projects can have their own dependencies, preventing conflicts between different projects. It allows you to manage packages for specific projects without affecting the global Python installation or other projects.
To create a virtual environment, you can use the following command in your terminal:
Code


python -m venv <environment_name>


Replace <environment_name> with the desired name for your virtual environment (e.g., .venv, myenv). This command creates a directory containing the necessary files for the virtual environment.
To activate the virtual environment, use one of the following commands, depending on your operating system: On Windows.
Code


<environment_name>\Scripts\activate


On macOS and Linux.
Code


source <environment_name>/bin/activate


Once activated, the environment name will appear in parentheses or brackets at the beginning of your terminal prompt, indicating that you are working within the virtual environment.
To deactivate the virtual environment, simply type deactivate in the terminal.
Code


deactivate


When the virtual environment is deactivated, you will revert back to the global Python environment.
