4.26.4 pyobject related functions
attrib
- list, get and set attributes (class members) of a pyobject (see attrib)
Example:
| | pyobject pystr = "Kublai Khan";
// Additional functionality through attrib
attrib(pystr, "__doc__");
==> "str(object='') -> string\n\nReturn a nice string representation of the o\
bject.\nIf the argument is a string, the return value is the same object.\
"
proc(attrib(pystr, "count"))("K");
==> 2
pystr."__doc__"; // <- Short notations
==> "str(object='') -> string\n\nReturn a nice string representation of the o\
bject.\nIf the argument is a string, the return value is the same object.\
"
pystr.count("a"); // Even shorter (if attribute's name is valid and unused)
==> 2
python_run("def func(): return 17");
attrib(func);
==> ['__call__', '__class__', '__closure__', '__code__', '__defaults__', '__d\
elattr__', '__dict__', '__doc__', '__format__', '__get__', '__getattribut\
e__', '__globals__', '__hash__', '__init__', '__module__', '__name__', '_\
_new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__siz\
eof__', '__str__', '__subclasshook__', 'func_closure', 'func_code', 'func\
_defaults', 'func_dict', 'func_doc', 'func_globals', 'func_name']
attrib(func, "func_name");
==> 'func'
attrib(func, "func_name", "byAnyOtherName");
attrib(func, "func_name");
==> 'byAnyOtherName'
|
killattrib
- deletes an attribute from a pyobject (see killattrib)
Example:
| | LIB("pyobject.so");
python_run("def new_pyobj(): pass");
attrib(new_pyobj, "new_attr", "something");
attrib(new_pyobj, "new_attr");
==> 'something'
attrib(new_pyobj);
==> ['__call__', '__class__', '__closure__', '__code__', '__defaults__', '__d\
elattr__', '__dict__', '__doc__', '__format__', '__get__', '__getattribut\
e__', '__globals__', '__hash__', '__init__', '__module__', '__name__', '_\
_new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__siz\
eof__', '__str__', '__subclasshook__', 'func_closure', 'func_code', 'func\
_defaults', 'func_dict', 'func_doc', 'func_globals', 'func_name', 'new_at\
tr']
killattrib(new_pyobj, "new_attr");
attrib(new_pyobj);
==> ['__call__', '__class__', '__closure__', '__code__', '__defaults__', '__d\
elattr__', '__dict__', '__doc__', '__format__', '__get__', '__getattribut\
e__', '__globals__', '__hash__', '__init__', '__module__', '__name__', '_\
_new__', '__reduce__', '__reduce_ex__', '__repr__', '__setattr__', '__siz\
eof__', '__str__', '__subclasshook__', 'func_closure', 'func_code', 'func\
_defaults', 'func_dict', 'func_doc', 'func_globals', 'func_name']
