Typing string.whitespace gives you a string containing all whitespace characters defined by Python\'s string module:

\'\\t\\n\\x0b\\x0c

    \v is \x0b:

    >>> '\v'
    '\x0b'
    

    but the string literal representation in Python is using the \x0b notation instead.

    The Python string literal representation only ever uses \n, \r and \t, everything else that is not a printable ASCII character is represented using the \xhh notation instead.

    \x0c is a form feed; it forces a printer to move to the next sheet of paper. You can also express it as \f in Python:

    >>> '\f'
    '\x0c'
    

    In terminals the effects of \v and \f are often the same.
