How to get the list of options that Python was compiled with?

You can compile Python in various ways. I'd like to find out with which options my Python was compiled. Concrete use-case: was my Python compiled with readline? I know I can see this by doing "import readline", but I'd like to see a list of compilation setting for my Python binary. Edit: I mean the Python executable and not source code written by myself.
There is a module to see the system config import sysconfig print(sysconfig.get_config_vars()) It offers an interface to get individual variables as well. sysconfig.get_config_var('HAVE_LIBREADLINE') It is also accessible via shell: python3 -m sysconfig | less Edit: before python2.7, you have to use import distutils.sysconfig print distutils.sysconfig.get_config_vars()
