Print an object o, on file fp. Returns -1 on error
The flags argument is used to enable certain printing
options. The only option currently supported is
Py_PRINT_RAW.
Returns 1 if o has the attribute attr_name, and
0 otherwise. This is equivalent to the Python expression
"hasattr(o, attr_name)".
This function always succeeds.
Retrieve an attribute named attr_name from object o.
Returns the attribute value on success, or NULL on failure.
This is the equivalent of the Python expression
"o.attr_name".
Returns 1 if o has the attribute attr_name, and
0 otherwise. This is equivalent to the Python expression
"hasattr(o, attr_name)".
This function always succeeds.
Retrieve an attribute named attr_name from object o.
Returns the attribute value on success, or NULL on failure.
This is the equivalent of the Python expression
"o.attr_name".
Set the value of the attribute named attr_name, for object
o, to the value v. Returns -1 on failure. This is
the equivalent of the Python statement "o.attr_name =
v".
int PyObject_SetAttr(PyObject *o, PyObject *attr_name, PyObject *v)
Set the value of the attribute named attr_name, for
object o,
to the value v. Returns -1 on failure. This is
the equivalent of the Python statement "o.attr_name =
v".
Delete attribute named attr_name, for object o. Returns
-1 on failure. This is the equivalent of the Python
statement "del o.attr_name".
int PyObject_Cmp(PyObject *o1, PyObject *o2, int *result)
Compare the values of o1 and o2 using a routine provided
by o1, if one exists, otherwise with a routine provided by
o2. The result of the comparison is returned in result.
Returns -1 on failure. This is the equivalent of the Python
statement "result = cmp(o1, o2)".
Compare the values of o1 and o2 using a routine provided
by o1, if one exists, otherwise with a routine provided by
o2. Returns the result of the comparison on success. On error,
the value returned is undefined; use PyErr_Occurred() to
detect an error. This is equivalent to the
Python expression "cmp(o1, o2)".
Compute the string representation of object, o. Returns the
string representation on success, NULL on failure. This is
the equivalent of the Python expression "repr(o)".
Called by the repr() built-in function
and by reverse quotes.
Compute the string representation of object o. Returns the
string representation on success, NULL on failure. This is
the equivalent of the Python expression "str(o)".
Called by the str() built-in function and
by the print statement.
Call a callable Python object callable_object, with
arguments given by the tuple args. If no arguments are
needed, then args may be NULL. Returns the result of the
call on success, or NULL on failure. This is the equivalent
of the Python expression "apply(o, args)".
Call a callable Python object callable_object, with a
variable number of C arguments. The C arguments are described
using a Py_BuildValue() style format string. The format may
be NULL, indicating that no arguments are provided. Returns the
result of the call on success, or NULL on failure. This is
the equivalent of the Python expression "apply(o,
args)".
Call the method named m of object o with a variable number
of C arguments. The C arguments are described by a
Py_BuildValue() format string. The format may be NULL,
indicating that no arguments are provided. Returns the result of the
call on success, or NULL on failure. This is the equivalent of the
Python expression "o.method(args)".
Note that Special method names, such as __add__(),
__getitem__(), and so on are not supported. The specific
abstract-object routines for these must be used.
Returns 1 if the object o is considered to be true, and
0 otherwise. This is equivalent to the Python expression
"not not o".
This function always succeeds.
On success, returns a type object corresponding to the object
type of object o. On failure, returns NULL. This is
equivalent to the Python expression "type(o)".
Return the length of object o. If the object o provides
both sequence and mapping protocols, the sequence length is
returned. On error, -1 is returned. This is the equivalent
to the Python expression "len(o)".
