class AugAssign(_base_nodes.AssignTypeNode, _base_nodes.Statement): (source)

View In Hierarchy

Class representing an :class:`ast.AugAssign` node. An :class:`AugAssign` is an assignment paired with an operator. >>> import astroid >>> node = astroid.extract_node('variable += 1') >>> node <AugAssign l.1 at 0x7effe1db4d68>

Method __init__ :param op: The operator that is being combined with the assignment. This includes the equals sign.
Method get_children Get the child nodes below this node.
Method postinit Do some setup after initialisation.
Method type_errors Get a list of type errors which can occur during inference.
Class Variable assigned_stmts Returns the assigned statement (non inferred) according to the assignment type. See astroid/protocols.py for actual implementation.
Instance Variable op The operator that is being combined with the assignment.
Instance Variable target What is being assigned to.
Instance Variable value The value being assigned to the variable.
Method _get_yield_nodes_skip_lambdas An AugAssign node can contain a Yield node in the value
Class Variable _astroid_fields Node attributes that contain child nodes.
Class Variable _infer_augassign Undocumented
Class Variable _other_fields Node attributes that do not contain child nodes.

overrides astroid.nodes.NodeNG.__init__

:param op: The operator that is being combined with the assignment. This includes the equals sign. :param lineno: The line that this node appears on in the source code. :param col_offset: The column that this node appears on in the source code. :param parent: The parent node in the syntax tree. :param end_lineno: The last line this node appears on in the source code. :param end_col_offset: The end column this node appears on in the source code. Note: This is after the last symbol.

def get_children(self): (source)
overrides astroid.nodes.NodeNG.get_children

Get the child nodes below this node.

def postinit(self, target: NodeNG|None = None, value: NodeNG|None = None): (source)

Do some setup after initialisation. :param target: What is being assigned to. :param value: The value being assigned to the variable.

def type_errors(self, context: InferenceContext|None = None): (source)

Get a list of type errors which can occur during inference. Each TypeError is represented by a :class:`BadBinaryOperationMessage` , which holds the original exception. :returns: The list of possible type errors. :rtype: list(BadBinaryOperationMessage)

assigned_stmts: ClassVar[AssignedStmtsCall[AugAssign]] = (source)

Returns the assigned statement (non inferred) according to the assignment type. See astroid/protocols.py for actual implementation.

op: str|None = (source)

The operator that is being combined with the assignment. This includes the equals sign.

target = (source)

What is being assigned to.

value = (source)

The value being assigned to the variable.

def _get_yield_nodes_skip_lambdas(self): (source)
overrides astroid.nodes.NodeNG._get_yield_nodes_skip_lambdas

An AugAssign node can contain a Yield node in the value

_astroid_fields: tuple[str, ...] = (source)
