Return 1 if the object provides sequence protocol, and
0 otherwise. This function always succeeds.
int PySequence_Size(
PyObject *o)
Returns the number of objects in sequence o on success, and
-1 on failure. For objects that do not provide sequence
protocol, this is equivalent to the Python expression
"len(o)".
int PySequence_Length(
PyObject *o)
Alternate name for PySequence_Size().
PyObject* 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".
PyObject* PySequence_Repeat(
PyObject *o, int count)
Return value:New reference.
Return the result of repeating sequence object ocount
times, or NULL on failure. This is the equivalent of the Python
expression "o * count".
PyObject* 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".
PyObject* PySequence_InPlaceRepeat(
PyObject *o, int count)
Return value:New reference.
Return the result of repeating sequence object ocount
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".
PyObject* PySequence_GetItem(
PyObject *o, int 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]".
PyObject* PySequence_GetSlice(
PyObject *o, int i1, int 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]".
int PySequence_SetItem(
PyObject *o, int i, PyObject *v)
Assign object v to the ith element of o. Returns
-1 on failure. This is the equivalent of the Python
statement "o[i] = v". This function does not
steal a reference to v.
int PySequence_DelItem(
PyObject *o, int i)
Delete the ith element of object o. Returns -1
on failure. This is the equivalent of the Python statement
"del o[i]".
int PySequence_SetSlice(
PyObject *o, int i1,
int i2, PyObject *v)
Assign the sequence object v to the slice in sequence object
o from i1 to i2. This is the equivalent of the
Python statement "o[i1:i2] = v".
int PySequence_DelSlice(
PyObject *o, int i1, int 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]".
PyObject* PySequence_Tuple(
PyObject *o)
Return value:New reference.
Returns the o as a tuple on success, and NULL on failure.
This is equivalent to the Python expression "tuple(o)".
int 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)".
int PySequence_Contains(
PyObject *o, PyObject *value)
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".
int 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)".
PyObject* 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.
PyObject* PySequence_Tuple(
PyObject *o)
Return value:New reference.
Return a tuple object with the same contents as the arbitrary
sequence o. If o is a tuple, a new reference will be
returned, otherwise a tuple will be constructed with the appropriate
contents.
PyObject* PySequence_Fast(
PyObject *o, const 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(
PyObject *o, int 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_ITEM(
PyObject *o, int 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.
New in version 2.3.
int PySequence_Fast_GET_SIZE(
PyObject *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.
