How to install dnf in amazon linux 2?

Hi. How about installing dnf not via yum but via rpm. I found the Japanese article which installs dnf to AL2. Hope this article will help you.(please translate it) https://qiita.com/deracio/items/db6a95be6bc5f795a968

For DNF I have not been able to get it work on Amazon Linux 2 however, I have been able to install python3.9 on it. You can follow the steps below and revert.

1. sudo yum update
2. sudo yum upgradew
3. get https://www.python.org/ftp/python/3.9.15/Python-3.9.15.tgz
4. ls -la
5. tar xzf Python-3.9.15.tgz
6. ls -la
7. cd Python-3.9.15/
8. sudo ./configure --enable-optimizations
9. sudo make altinstall

1). check python versions and their directories whereis python3

2). test python3.9 by using it python3.9

3). Set python3 version variable alternatives --set python /usr/bin/python3.9

4). Check the python3.9 version python3 -V

or python3 --version
