"""
help([object])
Invoke the built-in help system. (This function is intended for interactive 
use.) If no argument is given, the interactive help system starts on the 
interpreter console. If the argument is a string, then the string is looked 
up as the name of a module, function, class, method, keyword, or 
documentation topic, and a help page is printed on the console. If the 
argument is any other kind of object, a help page on the object is 
generated.
