def SagePromptTransformer():
    r"""
    Strip the sage:/....: prompts of Sage.

    EXAMPLES::

        sage: from sage.repl.interpreter import SagePromptTransformer
        sage: spt = SagePromptTransformer()
        sage: spt.push("sage: 2 + 2")
        '2 + 2'
        sage: spt.push('')
        ''
        sage: spt.push("....: 2+2")
        '2+2'

    This should strip multiple prompts: see :trac:`16297`::

        sage: spt.push("sage:   sage: 2+2")
        '2+2'
        sage: spt.push("   sage: ....: 2+2")
        '2+2'

    The prompt contains a trailing space. Extra spaces between the
    last prompt and the remainder should not be stripped::

        sage: spt.push("   sage: ....:    2+2")
        '   2+2'

    We test that the input transformer is enabled on the Sage command
    line::

        sage: from sage.repl.interpreter import get_test_shell
        sage: shell = get_test_shell()
        sage: shell.run_cell('sage: a = 123')              # single line
        sage: shell.run_cell('sage: a = [\n... 123]')      # old-style multi-line
        sage: shell.run_cell('sage: a = [\n....: 123]')    # new-style multi-line

    We test that :trac:`16196` is resolved::

        sage: shell.run_cell('    sage: 1+1')
        2
        sage: shell.quit()
