How to uninstall Python if it just throws an error when uninstalling and installing?

Question

Windows

Hello! Recently I wanted to reinstall Python. But when I deleted it, I made a very big mistake... I deleted all the folders manually. Now, even when uninstalling in the Python installer, it gives an error and closes (the same with the installation) - when I wanted to uninstall through the Windows control panel, it was transferred to the Python installer. Tell me what to do?

Answer 1

1) Clean up environment variables.
2) Look, maybe there are folders left, or python (or installation) hangs in processes.
3) Run the installation on behalf of ̶sh̶a̶m̶a̶n̶a̶ Admin.

But when I deleted it, I made a very big mistake...

Firstly, it's not a big mistake, and secondly, it's not like a mistake. If you demolish the folder with Python, then nothing terrible will happen. If the installer does not work after that, most likely either a left-handed truncated assembly of Windows, or a problem in the system itself.
