Chapter 2: Setting Up the Environment
2.3 Working with Virtual Environments in Python
When working on Python projects, it's a good practice to create a virtual environment. A virtual environment is a self-contained directory that contains a Python installation for a particular version of Python, plus a number of additional packages. Creating a virtual environment has several benefits.
First, it allows you to work on multiple projects with different dependencies without interfering with each other. Second, it ensures that you have a consistent set of packages for a particular project, which can help with reproducibility. Third, it can help you avoid conflicts between different versions of packages that you might have installed globally on your system.
To create a virtual environment, you can use a tool called virtualenv, which is available for Python 2 and Python 3. Virtualenv allows you to create a new virtual environment with a specific version of Python, and then activate that environment when you want to work on that project.
Once you've activated the virtual environment, any packages you install will be installed into that environment, rather than globally on your system. This helps to keep your system clean and avoid conflicts between packages.
Creating a virtual environment allows you to work on multiple projects that have different dependencies without conflicts between them. You can create a new virtual environment using the venv
module that comes with Python:
python3 -m venv myenv
To activate the virtual environment:
- On Windows:
myenv\Scripts\activate
- On Unix or MacOS:
source myenv/bin/activate
