Install Python 3.12 && Pycharm 2023.3 along with system-wide 3.11 on Manjaro KDE 23.1

 Pyenv is a tool for managing multiple Python versions. Once pyenv is installed you can easily switch between one project that uses Python 3.12 and a system-wide default Python 3.11. Same approach works fine on openSUSE Tumbleweed, SparkyLinux 7.2, SparkyLinux 2024.1

$ sudo pacman -S pyenv

The following two installs are required to perform successful build Python 3.12.1 for particular user via pyenv. This build won't affect system-wide Python 3.11.6 

$ sudo pacman -S base-devel

$ sudo pacman -S tk

Now we update ~/.zshrc in the same way as  did it for ~/.bashrc in cases mentioned above .

$ echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc

$ echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >>  ~/.zshrc

$ echo 'eval "$(pyenv init --path)"' >> ~/.zshrc

$ source  ~/.zshrc

$ pyenv install 3.12.1
