Installing Python

Start by installing Python for your operating system. Make sure that pip is installed as well.

Linux

On debian-based Linux distributions, you should install the following

sudo apt install python3-pip

Most likely, you also want install

sudo apt install python-is-python3

This allows you to use python and pip in lieu of python3 and pip3.

Windows

On Windows, download and install Python from python.org. Make sure to select pip to be installed as well and that Python will be available through your operating systems PATH variable. You might need to select these from advanced options during the installation.

If you already have a working installation of Python, but still require pip, follow the instructions for installing pip.

Usually, Python will be available as py in the Windows terminal. If you do not want to add the relevant directories to your PATH variable, it should be possible to run py whenever python is executed here and py -m name when a Python program (like pip) is executed. That means, for example, instead of writing

pip install --user --upgrade pip

you should be able to write

py -m pip install --user --upgrade pip

on Windows, even without adding the relevant directories to your PATH.

Installing Packages

When installing packages, always make sure to upgrade pip first.

pip install --user --upgrade pip

When pip is up to date, install the packages you desire (for example, numpy, pandas and jupyterlab).

pip install --user --upgrade numpy pandas jupyterlab
