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")Perl time:
sub AUTOLOAD { our $AUTOLOAD=~s/.*:://; no strict; local $_=$_[0] and *STDOUT->$_($AUTOLOAD) } HelloWorld("print");Pro: You can Give HelloWorld any (syntactically valid) name you like and (as long as the parameter is
"print", anyway) its name will be printed, no pre-declaration required.Con: The specified function inside the quotes has to be a method associated with a file descriptor.
