Showcasing how to gain access to the builtins from a simple literal, proving that eval and exec can always be exploited no matter which safeguards you put in place. (Tested in python 3.7)
"""
This code gains access to the builtins from a simple literal. As a consequence,
we can conclude that `eval` and `exec` are insecure even if the evaluated code
has no (direct) access to the builtins or globals.
Of course, there are ways to break this particular exploit - for example,

import abc
del abc.__loader__
will prevent it from working. But that only protects you against this particular
