In Linux:

1. Select the version that you're looking for: https://www.python.org/downloads/
2. From the appropriate version's page, copy the download link. (eg. https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tgz)
3. Go to the directory you want to download the compressed package to and run wget "https://www.python.org/ftp/python/3.8.3/Python-3.8.3.tgz"
4. In that same directory, run tar -zxvf Python-3.8.3.tgz to extract Python
5. cd into the directory where Python has been extracted to
6. Run ./configure
7. Run make
8. Run make install
9. Run python --version to check that the installation was successful

Python should now be installed at the desired version.
