Dict

class astroid.nodes.Dict(lineno: int | None, col_offset: int | None, parent: NodeNG | None, *, end_lineno: int | None, end_col_offset: int | None)

Bases: NodeNG, DictInstance

Class representing an ast.Dict node.

A Dict is a dictionary that is created with {} syntax.

>>> import astroid
>>> node = astroid.extract_node('{1: "1"}')
>>> node
<Dict.dict l.1 at 0x7f23b2e35cc0>

bool_value(context: InferenceContext | None = None)

Determine the boolean value of this node.

Returns:

The boolean value of this node.

Return type:

bool

get_children()

Get the key and value nodes below this node.

Children are returned in the order that they are defined in the source code, key first then the value.

Returns:

The children.

Return type:

iterable(NodeNG)

getitem(index: Const | Slice, context: InferenceContext | None = None) → NodeNG

Get an item from this node.

Parameters:

index – The node to use as a subscript index.

Raises:

• AstroidTypeError – When the given index cannot be used as a subscript index, or if this node is not subscriptable.

• AstroidIndexError – If the given index does not exist in the dictionary.

infer_unary_op(op)

items: list[tuple[InferenceResult, InferenceResult]]

The key-value pairs contained in the dictionary.

itered()

An iterator over the keys this node contains.

Returns:

The keys of this node.

Return type:

iterable(NodeNG)

last_child()

An optimized version of list(get_children())[-1]

Returns:

The last child, or None if no children exist.

Return type:

NodeNG or None

postinit(items: list[tuple[InferenceResult, InferenceResult]]) → None

Do some setup after initialisation.

Parameters:

items – The key-value pairs contained in the dictionary.

pytype() → Literal['builtins.dict']

Get the name of the type that this node represents.

Returns:

The name of the type.
