Hello, thank you for writing this code. I'd like to leverage your code to automate the installation of the Ansible Control Node latest version (ie 2.8). The host OS will be RHEL 7.7 vs. Debian. Question - it appears for Python to run a GCC is required - is this true?

Yes, the CPython (the python we use) interpreter is written in C.
