Developer work on a different project at the same time at the same machine. And every project has different dependencies, for this reason, we need to create such an environment in which every project should be separated from another one. To complete this idea, a virtual environment concept is developed it means you can create an environment in which you will get an isolated python installed environment.

When you create a virtual environment you will get all the files/folders when you install python globally e.g pip etc. So, in that environment you will be allowed to create a project that will be separated from another project, you can set its own version to mix up with other versions of another environment.

Why need of Virtual Environment

Actually, there are some reasons you have to build your project in a virtual environment that points I want to share with you.

1. If you want to work on another project on the same machine, then you have to think about VE.

2. You also need when you want to work on different versions of Python

3. Other reasons, if your python project version is 2.0 without virtual environment and you have launched that project also on the hand of users. When other releases come e.g 3.0 then it may be some issue with your previous project because there may be some functions, module stop working because the new update is released. And you know when a new update has released some functions or models are changed to another one. Then your project will be affected by releasing a new update. So, you have to build your project in a virtual environment to avoid such kinds of difficulties.

We have written a complete guide on the need for a virtual environment you can read that tutorial from starting to end.
