我正在Win 10下使用Msys2 Portable。我似乎有2个python 3.8安装
$ pacman -Sl | grep "python " | grep "installed"
mingw64 mingw-w64-x86_64-python 3.8.2-2 [installed]
msys python 3.8.2-1 [installed]
它们实际上是两个单独的python系统，还是它们是两个软件包，而这两个软件包都需要python才能工作？
如果它们是分开的，它们可以互相干扰吗？删除其中任何一个是否安全（我的意思是使用numpy，pandas和许多其他软件包）？哪一个是最好的保留？
对我来说，奇怪的是，即使版本都是3.8.2，可用的版本也不完全相同。
PS1：这是python2的补充，适用于相同的问题。
$ pacman -Sl | grep "python2 " | grep "installed"
mingw64 mingw-w64-x86_64-python2 2.7.18-1 [installed: 2.7.17-2]
msys python2 2.7.18-1 [installed: 2.7.17-1]
PS2：这两个python可能是this "play"主要字符的升级，python 3.8（之前的3.8.1）已升级为mingw-w64-x86_64-python 3.8.2-2，python 3.7则已升级为python。
根据下面的输出，显示了与其他软件包的关系，看起来它们是独立的python系统。
