This Commands Will Install Multiple Python-3.11.x Into Ubuntu 24.04 LTS

How To Install Python Ubuntu 24.04 LTS

# !/bin/sh
# Install Python 3 on Ubuntu From Source

sudo -i
apt update && apt upgrade -y
apt install build-essential zlib1g-dev libncurses5-dev libgdbm-dev libnss3-dev libssl-dev libreadline-dev libffi-dev libsqlite3-dev wget libbz2-dev
apt install build-essential checkinstall
apt autoremove
apt install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev libffi-dev zlib1g-dev
cd /opt
wget https://www.python.org/ftp/python/3.11.0/Python-3.11.0.tgz
tar xzf Python-3.11.0.tgz
rm -f Python-3.11.0.tgz
cd Python-3.11.0

./configure --enable-optimizations
make altinstall
apt install python3-pip
cd
nano ~/.bashrc
# Add into the bottom 
alias python=python3
alias pip=pip3
# Save & Exit ctrl+s and ctrl+x

alias python=python3
alias pip=pip3
source ~/.bashrc
sudo apt update
sudo apt upgrade -y
python --version
pip --version

# Install Python using PPA
sudo apt install software-properties-common
sudo add-apt-repository ppa:deadsnakes/ppa
sudo apt update
sudo apt install python3.12

# Switch Python version
update-alternatives --config python3

# install Python using SNAP
snap install python38 --classic
python3 --version

How does this upgrade to 3.9 when it explicitly states 3.10?

> wget https://www.python.org/ftp/python/3.10.7/Python-3.10.7.tgz
> tar xzf Python-3.10.7.tgz
> rm -f Python-3.10.7.tgz
> cd Python-3.10.7

That being said changing the 10.7 to 9.9 resolves the problems.

@coderhard Thanks
just update

i did here every thing in this gist but problem is i can't switch 1 python version to another version python so i found some error like cd /opt download python update version into this and after i install into this folder but everything goes well when i use switch command showing update-alternatives: error: no alternatives for python3....... so i linked /usr/bin/python3 python3 /opt/python3.10. 1 then its work. so i am facing another problem now my python version not showing LoL so i am trying to solve it...
Happy error hunting

If Python version switching is working and you can select multiple version python your setup it ready to go!
