|
|
|
|
# PyTypeObject PyDict_Type
|
|
#
|
|
# This instance of PyTypeObject represents the Python dictionary

|
# type. This is exposed to Python programs as dict and

|
# types.DictType.

|
|
# Return value: New reference.
|
|
# Return a proxy object for a mapping which enforces read-only

# behavior. This is normally used to create a proxy to prevent
|
|
# modification of the dictionary for non-dynamic class types.

|
# Library Reference).

# pairs have been reported. The parameters pkey and pvalue should
|
|
# either point to PyObject* variables that will be filled in with
|
|
# each key and value, respectively, or may be NULL. Any references
|
|
# returned through them are borrowed. ppos should not be altered
|
|
# during iteration. Its value represents offsets within the
|
|
# internal dictionary structure, and since the structure is
|
|
# sparse, the offsets are not consecutive.
|

# For example:
|
|
#
|
|
#object key, *value;

#int pos = 0;

# The dictionary p should not be mutated during iteration. It is
|
|
# safe (since Python 2.1) to modify the values of the keys as you
|
|
# iterate over the dictionary, but only so long as the set of keys
|
|
# does not change. For example:
|
|
# object key, *value;
|
|
# int pos = 0;
|
|
# while (PyDict_Next(self->dict, &pos, &key, &value)) {
|
|
# int i = PyInt_AS_LONG(value) + 1;
|
|
# object o = PyInt_FromLong(i);
|
|
# if (o == NULL)
|
|
# return -1;
|

# Py_DECREF(o);

# existing pairs in a will be replaced if a matching key is found

|
int PyDict_MergeFromSeq2(object a, object seq2, int override) except -1
|
|
# Update or merge into dictionary a, from the key-value pairs in

|
|
# of length 2, viewed as key-value pairs. In case of duplicate
|
|
# keys, the last wins if override is true, else the first
|
|
# wins. Return 0 on success or -1 if an exception was
|
|
# raised. Equivalent Python (except for the return value):
|
|
#
|
|
#def PyDict_MergeFromSeq2(a, seq2, override):
|
|
# for key, value in seq2:
|
|
# if override or key not in a:
