What is the difference between the help() and dir() functions in Python?

help() provides an interactive help system, displaying the documentation (docstring) of objects. dir() returns a list of valid attributes of an object.

Example of using help():

help(str)

// Displays documentation for the string type.

Example of using dir():

dir(list)

// Returns a list of methods and attributes available for list objects.
