format()to convert a value to a formatted representation
frozenset()to return a new frozenset object
getattr()to return the value of the named attribute of object
globals()to return a dictionary representing the current global symbol table

iter()to return an iterator object
len()to return the length or the item number of an object
list()to return a list object
locals()to update and return a dictionary representing the current local symbol table

str()to return a str version of object
sum()to return the total of iterable from left to right
super()to return a proxy object that delegates method calls to a parent or sibling class of type.
tuple()to return a tuple
type()to return the type of an object
vars()to return the __dict__ attribute for a module, class, instance, or any othe object with a __dict__ attribute
