Updating Python 3.7 to 3.8 on Raspberry Pi

Question

I recently updated my Raspberry Pi with sudo apt update and sudo apt full-upgrade to the system. Even if Python 3.8 is out, when I run python3 in terminal, it shows me version 3.7, instead of 3.8.

Why is this the case?

Answer 1

Why? Just because it takes a while for distributions to integrate new versions.

Here's what I did to install Python 3.8.5 on my rpi:

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
version=3.8.5
wget https://www.python.org/ftp/python/$version/Python-$version.tgz
tar zxf Python-$version.tgz
cd Python-$version
./configure --enable-optimizations
make -j4
sudo make altinstall

Installs Python into /usr/local/bin

Answer 2

This is worth sharing, someone made a bash script.
