I am trying to compile Python 3 on Centos7 and I am getting "ModuleNotFoundError: No module named '_ctypes'"

I'm not sure that you are asking on the right mailing list. Anyway.

Red Hat provides precompiled Python 3.6 for Centos 7: https://www.softwarecollections.org/en/scls/rhscl/rh-python36/

About your error, you likely miss some header files, like libffi-devel:

sudo yum install -y libffi-devel

That issue has been reported some times before as well at bpo. Maybe providing a proper error message for the missing libffi headers would be good, as the current one is quite cryptic.

Victor, Thanks a bunch! Issue closed! It saved my day! The FIX: "sudo yum install -y libffi-devel", fixed the 3.7.3 compile error! Have a great day!
