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

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.

• An Intro to Threading in Python (Real Python)
• How can I use threading in Python? on StackOverflow
• Parallelism in One Line (multiprocessing in Python, how to avoid boilerplate producer-consumer-queueing code by injecting parallelism into the code using Map, a functional programming concept)
• Multithreading vs Multiprocessing in Python on the Noteworthy blog
