7/29/2023 0 Comments Python virtualenvYour new virtual environment has its own pip to install libraries, its own libraries folder, where new libraries are added, and its own Python interpreter for the Python version you used to activate the environment. To break this down, when you activate a virtual environment for your project, your project becomes its own self contained application, independent of the system installed Python and its modules. Python's official documentation says: "A virtual environment is a Python environment such that the Python interpreter, libraries and scripts installed into it are isolated from those installed in other virtual environments, and (by default) any libraries installed in a “system” Python, i.e., one which is installed as part of your operating system" ![]() This tutorial will cover everything you need to know about virtual environments and how to set one up with Virtualenv. ![]() And to get around this, we can use virtual environments. This is a scenario you can run into when building software with Python. When you go back to run your app A, you get all sorts of errors, and your app does not run. Then you switch to project B on your local machine, and you install the same packageX but version 2.0, which has some breaking changes between version 1.0 and 2.0. As a result, you will need to isolate your Python development environment for that particular project.Ĭonsider this scenario: you are working on app A, using your system installed Python and you pip install packageX version 1.0 to your global Python library. But in complex software development projects, like building a Python library, an API, or software development kit, often you will be working with multiple files, multiple packages, and dependencies. This works fine for simple Python scripting projects. ![]() This is a common approach for a lot of beginners and many people transitioning from working with Python for data analytics. py file or notebook, and run your Python program in the terminal. When developing software with Python, a basic approach is to install Python on your machine, install all your required libraries via the terminal, write all your code in a single.
