PyMapping_Check
(
PyObject
*o
)
¶
返回
1
if the object provides mapping protocol, and
0
otherwise. This function always succeeds.
PyMapping_Size
(
PyObject
*o
)
¶
PyMapping_Length
(
PyObject
*o
)
¶
Returns the number of keys in object
o
on success, and
-1
on failure. For objects that do not provide mapping protocol, this is equivalent to the Python expression
len(o)
.
PyMapping_DelItemString
(
PyObject
*o
, const char
*key
)
¶
Remove the mapping for object
key
from the object
o
。返回
-1
on failure. This is equivalent to the Python statement
del o[key]
.
PyMapping_DelItem
(
PyObject
*o
,
PyObject
*key
)
¶
Remove the mapping for object
key
from the object
o
。返回
-1
on failure. This is equivalent to the Python statement
del o[key]
.
PyMapping_HasKeyString
(
PyObject
*o
, const char
*key
)
¶
On success, return
1
if the mapping object has the key
key
and
0
otherwise. This is equivalent to the Python expression
key in o
. This function always succeeds.
PyMapping_HasKey
(
PyObject
*o
,
PyObject
*key
)
¶
返回
1
if the mapping object has the key
key
and
0
otherwise. This is equivalent to the Python expression
key in o
. This function always succeeds.
PyMapping_Keys
(
PyObject
*o
)
¶
On success, return a list of the keys in object
o
. On failure, return
NULL
. This is equivalent to the Python expression
list(o.keys())
.
PyMapping_Values
(
PyObject
*o
)
¶
On success, return a list of the values in object
o
. On failure, return
NULL
. This is equivalent to the Python expression
list(o.values())
.
PyMapping_Items
(
PyObject
*o
)
¶
On success, return a list of the items in object
o
, where each item is a tuple containing a key-value pair. On failure, return
NULL
. This is equivalent to the Python expression
list(o.items())
.
