Wiki: Python

This page is devoted to the Python programming language, including references to tutorials and particular, use of Python in programming robot control systems.

Upgrading to a Newer Version of Python#

To upgrade to a newer version of Python, e.g., 3.8.5:

sudo apt update

sudo apt-get install -y build-essential tk-dev libncurses5-dev libncursesw5-dev libreadline6-dev libdb5.3-dev libgdbm-dev libsqlite3-dev libssl-dev libbz2-dev libexpat1-dev liblzma-dev zlib1g-dev libffi-dev

wget https://www.python.org/ftp/python/3.8.5/Python-3.8.5.tgz

tar zxf Python-3.8.5.tgz
cd Python-3.8.5
./configure --enable-optimizations
make -j4
sudo make install

sudo make altinstall

if you don't want it to be the default.

Replace "3.8.5" above with whatever version you want to install. You can browse the directory at: https://www.python.org/ftp/python

Libraries#

gpiozero, a simple interface to everyday GPIO components used with Raspberry Pi. Installed on Raspbian by default; to install on other OS use: pip3 install gpiozero
igraph is a collection of network analysis tools with the emphasis on efficiency, portability and ease of use
- python-igraph
- iGraph Getting Started
NetworkX is a Python package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks. Also see networkx on github.
