sudo apt update，安裝Python 3sudo apt install python3，安裝完成后可通過python3 --version驗證安裝。sudo apt install software-properties-common，再添加PPAsudo add-apt-repository ppa:deadsnakes/ppa，更新列表后安裝所需版本，如sudo apt install python3.11。sudo apt install build-essential zlib1g-dev libssl-dev libreadline-dev libsqlite3-dev wget curl llvm libncurses5-dev libncursesw5-dev xz-utils tk-dev libffi-dev liblzma-dev python-openssl git，然后下載源碼wget https://www.python.org/ftp/python/版本號/Python-版本號.tgz，解壓后配置編譯./configure --enable-optimizations，make -j(nproc)，最后安裝sudo make altinstall。
