我犯了一个大错误。我在终端上发出了以下命令
sudo apt-get purge python
我没看出来它删除了什么 :(
我使用 LaTeX 排版系统，它的一些软件包现在无法正常工作。我已提出我的问题这里。
如果我丢失了 python 文件，是否需要重新安装完整的操作系统或者其他方法可以帮助我解决这个问题？

我复制了您的列表并将其与我已安装的程序（Ubuntu 19.04）进行了比较。然后，我删除了系统中“自动”生成的每个软件包。它们也将安装在您的系统上，但也会标记为“自动”。
sudo apt install asymptote feynmf fragmaster inkscape latex-cjk-all latex-cjk-thai lyx lyx-common prerex python-all python python-bs4 python-chardet python-crypto python-cycler python-dbus python-gi python-html5lib python-idna python-keyring python-lxml python-matplotlib python-pil python-pkg-resources python-pyparsing python-secretstorage python-six python-subprocess32 python-tz python-xdg qbittorrent texlive-extra-utils texlive-formats-extra texlive-full texlive-lang-other texlive-music texlive-pstricks texlive-science texlive-xetex vprerex
这些就是你必须安装的所有程序。标记为“自动”的程序将紧随其后。如果你想验证其余程序是否已安装，你可以运行
apt list python-all-dev python-asn1crypto python-backports.functools-lru-cache python-cffi-backend python-cryptography python-dateutil python-dev python-enum34 python-ipaddress python-keyrings.alt python-numpy python-olefile python-pip python-scour python-setuptools python-tk python-webencodings python-wheel texlive-latex-extra texlive-pictures
并检查其余部分是否已安装。如果没有，则以“手动”方式安装每个缺失部分。
