    bint PySequence_Check(object o)

    # otherwise. This function always succeeds.

    # Alternate name for PySequence_Size().

    object PySequence_Concat(object o1, object o2)
    # Return value: New reference.

    object PySequence_InPlaceConcat(object o1, object o2)
    # Return value: New reference.
    # Return the concatenation of o1 and o2 on success, and NULL on

    # Return value: New reference.
    # Return the result of repeating sequence object o count times, or

    # count".

    object PySequence_GetSlice(object o, Py_ssize_t i1, Py_ssize_t i2)
    # Return value: New reference.

    # Return the number of occurrences of value in o, that is, return

    # -1. This is equivalent to the Python expression
    # "o.count(value)".

    int PySequence_Contains(object o, object value) except -1
    # Determine if o contains value. If an item in o is equal to
    # value, return 1, otherwise return 0. On error, return -1. This
    # is equivalent to the Python expression "value in o".

    Py_ssize_t PySequence_Index(object o, object value) except -1
    # Return the first index i for which o[i] == value. On error,
    # return -1. This is equivalent to the Python expression
    # "o.index(value)".

    object PySequence_List(object o)
    # Return value: New reference.
    # Return a list object with the same contents as the arbitrary
    # sequence o. The returned list is guaranteed to be new.

    object PySequence_Tuple(object o)
    # Return value: New reference.
    # Return a tuple object with the same contents as the arbitrary
    # sequence o or NULL on failure. If o is a tuple, a new reference
    # will be returned, otherwise a tuple will be constructed with the
    # appropriate contents. This is equivalent to the Python
    # expression "tuple(o)".

    object PySequence_Fast(object o, char *m)
    # Return value: New reference.
    # Returns the sequence o as a tuple, unless it is already a tuple
    # or list, in which case o is returned. Use
    # PySequence_Fast_GET_ITEM() to access the members of the
    # result. Returns NULL on failure. If the object is not a
    # sequence, raises TypeError with m as the message text.

    PyObject* PySequence_Fast_GET_ITEM(object o, Py_ssize_t i)
    # Return value: Borrowed reference.
    # Return the ith element of o, assuming that o was returned by
    # PySequence_Fast(), o is not NULL, and that i is within bounds.

    PyObject** PySequence_Fast_ITEMS(object o)
    # Return the underlying array of PyObject pointers. Assumes that o
    # was returned by PySequence_Fast() and o is not NULL.

    object PySequence_ITEM(object o, Py_ssize_t i)
    # Return value: New reference.
    # Return the ith element of o or NULL on failure. Macro form of
    # PySequence_GetItem() but without checking that
    # PySequence_Check(o) is true and without adjustment for negative
    # indices.

    Py_ssize_t PySequence_Fast_GET_SIZE(object o)
    # Returns the length of o, assuming that o was returned by
    # PySequence_Fast() and that o is not NULL. The size can also be
    # gotten by calling PySequence_Size() on o, but
    # PySequence_Fast_GET_SIZE() is faster because it can assume o is
    # a list or tuple.
