Save the following line into a Python file. Let’s install pandas in this virtual environment and test if it works. To confirm that the virtual environment is activated, in the command prompt window, we should see (tut_venv) appear in front of the current input line. Simply in the command prompt type activate to activate the virtual environment. In the Scripts (or bin) folder, we should see a file named “activate”. Go into the subfolder by using the cd command cd tut_venv/Scripts #For Windows Once it’s created, we should see a folder called “tut_venv” appear in the current directory. I’m going to create a new virtual environment in the venv_tut folder: cd venv_tut Instead, we use it in a Command Prompt / Powershell / Terminal.īefore creating a virtual environment, we need to first decide where to place it, therefore we navigate to the desired folder location first. Unlike other libraries, we don’t import venv inside a Python interpreter. We are going to use a Python module called venv, which is part of Python standard library and comes with the Python installation. Create A Python Virtual Environment (venv) When we create multiple virtual environments, each instance is self-isolated and doesn’t interfere with other environments, so we can have different versions of a library on our computer at the same time.
CAN I USE PYTHON AND INSTALL JUPYTER NOTEBOOK SEPARATELY PLUS
Python Virtual Environment (venv) solves this problem by creating a self-contained copy of Python plus all the libraries. For example, if project A requires pandas version 1.0.1, and project B requires pandas version 1.2.0, there’s no way to install both on a computer.
These don’t come with the standard Python installation.ĭepending on the projects we work on, sometimes our task requires a specific version of a library, but we can keep only 1 version of a library at any given time. Most of the time when we use Python, we’ll need to use some third-party libraries, like pandas, plotly, xlwings, etc.
