How to Create and Use Python Virtual Environments (venv) on Ubuntu
Looking to manage Python dependencies without messing up your Ubuntu system? 🐍📦
In this DelftStack tutorial, we show you how to create, activate, and deactivate a Python virtual environment (venv) on Ubuntu. Virtual environments are crucial for developers because they allow you to keep project-specific libraries isolated from the global Python installation. We'll guide you through installing the necessary python3-venv package, creating your first environment, and verifying that it's active.
🔹 What You'll Learn in This Video:
✅ Installing the python3-venv package using apt.
✅ Creating a new virtual environment with python3 -m venv.
✅ Activating the environment using the source command.
✅ Recognizing the active state (looking for the parenthesis prompt).
✅ Deactivating the environment to return to the system Python.
💻 Commands Used in This Tutorial:
• Update package list: sudo apt update
• Install venv tool: sudo apt install python3-venv -y
• Create virtual environment: python3 -m venv my_env
• Activate environment: source my_env/bin/activate
• Deactivate environment: deactivate
