How to install dnf in amazon linux 2?

Question

Yum only supports python 3.7 packages. 
I need 3.9.16-1.amzn2023.0.3, it's available to install only through dnf as far as I am aware.

YUM is pointed to 3.7, DNF --> 3.9

Kindly provide support to use DNF or please let me know how to install python3-tkinter.x86_64 for python 3.9. 
Which is available in the link below.

Answer

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)

Answer

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
