PySequence_Check(PyObject *o)1 if the object provides sequence protocol, and 0 otherwise. This function always succeeds.PySequence_Size(PyObject *o)PySequence_Length(PyObject *o)Returns the number of objects in sequence o on success, and -1 on
failure. This is equivalent to the Python expression len(o).
Changed in version 2.5: These functions returned an int type. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_Concat(PyObject *o1, PyObject *o2)Return value: New reference.
Return the concatenation of o1 and o2 on success, and NULL on failure.
This is the equivalent of the Python expression o1 + o2.
PySequence_Repeat(PyObject *o, Py_ssize_t count)Return value: New reference.
Return the result of repeating sequence object o count times, or NULL on
failure. This is the equivalent of the Python expression o * count.
Changed in version 2.5: This function used an int type for count. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_InPlaceConcat(PyObject *o1, PyObject *o2)Return value: New reference.
Return the concatenation of o1 and o2 on success, and NULL on failure.
The operation is done in-place when o1 supports it. This is the equivalent
of the Python expression o1 += o2.
PySequence_InPlaceRepeat(PyObject *o, Py_ssize_t count)Return value: New reference.
Return the result of repeating sequence object o count times, or NULL on
failure. The operation is done in-place when o supports it. This is the
equivalent of the Python expression o *= count.
Changed in version 2.5: This function used an int type for count. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_GetItem(PyObject *o, Py_ssize_t i)Return value: New reference.
Return the ith element of o, or NULL on failure. This is the equivalent of
the Python expression o[i].
Changed in version 2.5: This function used an int type for i. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_GetSlice(PyObject *o, Py_ssize_t i1, Py_ssize_t i2)Return value: New reference.
Return the slice of sequence object o between i1 and i2, or NULL on
failure. This is the equivalent of the Python expression o[i1:i2].
Changed in version 2.5: This function used an int type for i1 and i2. This might
require changes in your code for properly supporting 64-bit systems.
PySequence_SetItem(PyObject *o, Py_ssize_t i, PyObject *v)Assign object v to the ith element of o. Raise an exception
and return -1 on failure; return 0 on success. This
is the equivalent of the Python statement o[i] = v. This function does
not steal a reference to v.
If v is NULL, the element is deleted, however this feature is
deprecated in favour of using PySequence_DelItem().
Changed in version 2.5: This function used an int type for i. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_DelItem(PyObject *o, Py_ssize_t i)Delete the ith element of object o. Returns -1 on failure. This is the
equivalent of the Python statement del o[i].
Changed in version 2.5: This function used an int type for i. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_SetSlice(PyObject *o, Py_ssize_t i1, Py_ssize_t i2, PyObject *v)Assign the sequence object v to the slice in sequence object o from i1 to
i2. Raise an exception and return -1 on failure; return 0 on success.
This is the equivalent of the Python statement o[i1:i2] = v.
If v is NULL, the slice is deleted, however this feature is
deprecated in favour of using PySequence_DelSlice().
Changed in version 2.5: This function used an int type for i1 and i2. This might
require changes in your code for properly supporting 64-bit systems.
PySequence_DelSlice(PyObject *o, Py_ssize_t i1, Py_ssize_t i2)Delete the slice in sequence object o from i1 to i2. Returns -1 on
failure. This is the equivalent of the Python statement del o[i1:i2].
Changed in version 2.5: This function used an int type for i1 and i2. This might
require changes in your code for properly supporting 64-bit systems.
PySequence_Count(PyObject *o, PyObject *value)Return the number of occurrences of value in o, that is, return the number
of keys for which o[key] == value. On failure, return -1. This is
equivalent to the Python expression o.count(value).
Changed in version 2.5: This function returned an int type. This might require changes
in your code for properly supporting 64-bit systems.
PySequence_Contains(PyObject *o, PyObject *value)1, otherwise return 0. On error, return -1. This is equivalent to the Python expression value in o.PySequence_Index(PyObject *o, PyObject *value)Return the first index i for which o[i] == value. On error, return
-1. This is equivalent to the Python expression o.index(value).
Changed in version 2.5: This function returned an int type. This might require changes
in your code for properly supporting 64-bit systems.
PySequence_List(PyObject *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.
PySequence_Tuple(PyObject *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).
PySequence_Fast(PyObject *o, const char *m)Return value: New reference.
Return the sequence o as a list, 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.
PySequence_Fast_GET_ITEM(PyObject *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.
Changed in version 2.5: This function used an int type for i. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_Fast_ITEMS(PyObject *o)Return the underlying array of PyObject pointers. Assumes that o was returned
by PySequence_Fast() and o is not NULL.
Note, if a list gets resized, the reallocation may relocate the items array. So, only use the underlying array pointer in contexts where the sequence cannot change.
New in version 2.4.
PySequence_ITEM(PyObject *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() on o is true and without adjustment for negative
indices.
New in version 2.3.
Changed in version 2.5: This function used an int type for i. This might require
changes in your code for properly supporting 64-bit systems.
PySequence_Fast_GET_SIZE(PyObject *o)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.
