Just so you know, those functions are also attributes of strings:

  >>> s = "foo"
  >>> s.upper()
  FOO

For documentation, rely on the __doc__ strings:

  >>> print s.upper.__doc__
  S.upper() -> string

  Return a copy of the ...

Or, use help():

  >>> help(s.upper)

(press q to close the resulting screen)

What do you mean by "cancel"?  Did you delete it?
