How to check if system is installed with latest python version (python3.10)?
问题
I am using following shell command to find the latest python is installed
$ python3 -c 'import sys; print(sys.version_info)'
sys.version_info(major=3, minor=8, micro=10, releaselevel='final', serial=0)
But this command is returning the default python version (3.8) that was pointing to python3, instead of higher python version installed (3.10).

你可以使用以下命令来查找已安装的所有Python版本（适用于具有默认路径安装Python的Red Hat和Debian衍生版本）：
ls /usr/bin/python* | grep -o '[0-9]\+\.[0-9]\+' | tr -d '.' | sort -n
要找到最新的版本，可以使用以下命令：
ls /usr/bin/python* | grep -o '[0-9]\+\.[0-9]\+' | tr -d '.' | sort -n | tail -n 1
如果要检查特定版本是否已安装，可以使用以下命令，例如，检查是否安装了Python 3.10：
test $(ls /usr/bin/python* | grep -o '[0-9]\+\.[0-9]\+' | tr -d '.' | sort -n | tail -n 1) -eq 310 && echo "Python version 3.10 is installed in this host." || echo "A version of python different than 3.10 is installed."
英文:
You can find out all your versions installed with (works with Red Hat and Debian derivatives with default path installations of python)
ls /usr/bin/python* | grep -o '[0-9]\+\.[0-9]\+' | tr -d '.' | sort -n
the latest with
ls /usr/bin/python* | grep -o '[0-9]\+\.[0-9]\+' | tr -d '.' | sort -n | tail -n 1
and to check for specific version
test $(ls /usr/bin/python* | grep -o '[0-9]\+\.[0-9]\+' | tr -d '.' | sort -n | tail -n 1) -eq 310 && echo "Python version 3.10 is installed in this host." || echo "A version of python different than 3.10 is installed."
