Default Versions of Python in CentOS

Depending on when you’re reading this or what version you’re using, the version that you have installed by default or the version that’s available in the CentOS repo might be different.

For CentOS 7:

• Python 2.7.5 is installed by default. That version has reached its EOL years ago, so you should upgrade ASAP.
• Python 3.6.8 is the latest version available in the CentOS 7 repos. 3.6 reached its EOL in Dec 2021, so you should upgrade ASAP.

For CentOS 8:

• Python isn’t installed by default.
• Python 3.9.6 is the latest version available in the CentOS 8 repos. The EOL of Python 3.9.6 is Oct 2025, so you can use that version. To install it, just run yum install python39 and that’s it. If you want to install Python 3.10 or 3.11, follow the tutorial below.
