Create a Python virtual environment (quick)

When working with Python, it’s best practice to use a separate virtual environment for each project to avoid dependency conflicts. Tools like PyCharm create virtual environments automatically, but you can just as easily do it via the command line:

1. cd to your project root and create a new virtual environment

   Running this command will create a .venv folder (a common name, but you can customize it if needed):
   

   python3 -m venv .venv
   

2. Activate the virtual environment
   

   source .venv/bin/activate
   

3. Once activated, your console should look like this:
   

   (.venv) <user>@<computer> <FolderName>
   

You can leave the virtual environment by executing deactivate.
