Python Environments Explained: Virtualenv
Imagine that each Python project is like a snake’s egg: an isolated ecosystem, with everything it needs to grow. If the eggs shared the same liquid, one could contaminate the others. Virtual environments work the same way: each .venv encapsulates the project’s dependencies, avoiding conflicts and ensuring everything runs independently.
Check Virtual Environment
which python⚠️ If no path is shown, Python is probably not installed on the system.
If the result is something like /usr/bin/python, it means the system’s default environment is being used.
On machines shared by multiple collaborators, check if the project has its own virtual environment and activate it to ensure local dependencies are used correctly. Look for files with something like .venv/bin/activate:
ls -a | grep "bin/activate"Create Virtual Environment
If the project is new or was cloned from a repository, it is necessary to create a virtual environment:
python3 -m venv .venvActivate Environment
source .venv/bin/activateDeactivate Environment
When you need to deactivate it, just run the following command:
deactivate⚠️ In some cases, the environment prefix in the prompt or even the output of the which python command may indicate the wrong virtual environment. A solution to this problem is simply to activate the desired environment again.
Conclusion
Just as a snake guards its clutch ensuring each egg is self-sufficient, virtual environments protect your projects from version conflicts and dependency errors. Explore more advanced tools like venv (for lightweight environments) or virtualenv/poetry (for more complex needs), always keeping the philosophy of the "isolated nest".
