I’m not surprised by anything at this point

Well well well, how the turned have tables, they have

import builtins

def HelloWorld(funcname):  
    getattr(builtins, funcname)("HelloWorld")

HelloWorld("print")

Edit, improved:

import inspect, builtins

def HelloWorld(funcname):
    caller = inspect.currentframe().f_code.co_name
    getattr(builtins, funcname)(caller)

HelloWorld("print")
