UnaryOp¶

class astroid.nodes.UnaryOp(op: str, lineno: int, col_offset: int, parent: NodeNG, *, end_lineno: int | None, end_col_offset: int | None)[source]¶

Bases: OperatorNode

Class representing an ast.UnaryOp node.

>>> import astroid
>>> node = astroid.extract_node('-5')
>>> node
<UnaryOp l.1 at 0x7f23b2e4e198>

get_children()[source]¶: Get the child nodes below this node.

op¶: The operator.

op_precedence() → int[source]¶

operand: NodeNG¶: What the unary operator is applied to.

postinit(operand: NodeNG) → None[source]¶

type_errors(context: InferenceContext | None = None) → list[BadUnaryOperationMessage][source]¶

Get a list of type errors which can occur during inference.

Each TypeError is represented by a BadUnaryOperationMessage, which holds the original exception.

If any inferred result is uninferable, an empty list is returned.
