在Ubuntu下安装Python常用方法如下：
sudo apt update，安装Python 3sudo apt install python3，安装完成后可通过python3 --version验证安装。sudo apt install software-properties-common，再添加PPAsudo add-apt-repository ppa:deadsnakes/ppa，更新列表后安装所需版本，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，然后下载源码wget https://www.python.org/ftp/python/版本号/Python-版本号.tgz，解压后配置编译./configure --enable-optimizations，make -j(nproc)，最后安装sudo make altinstall。
