    Iterate on the expression syntax and elements.

  • as_dict

    Return the expression as a dictionary.

  • iterate

    Iterate on the expression elements.

  • modernize

    Modernize the expression.

Attributes:

canonical_name property ¤

canonical_name: str

Name of the expressed name/attribute/parameter.

canonical_path property ¤

canonical_path: str

Path of the expressed name/attribute.

classname property ¤

classname: str

The expression class name.

is_classvar property ¤

is_classvar: bool

Whether this attribute is annotated with ClassVar.

is_generator property ¤

is_generator: bool

Whether this expression is a generator.

is_iterator property ¤

is_iterator: bool

Whether this expression is an iterator.

is_tuple property ¤

is_tuple: bool

Whether this expression is a tuple.

path property ¤

path: str

Path of the expressed name/attribute.

__iter__ ¤

__iter__() -> Iterator[str | Expr]

as_dict(**kwargs: Any) -> dict[str, Any]

Return the expression as a dictionary.

Parameters:

iterate ¤

iterate(*, flat: bool = True) -> Iterator[str | Expr]

Iterate on the expression elements.

Parameters:

  • flat ¤

    (bool, default: True ) –

    Expressions are trees.

    When flat is false, this method iterates only on the first layer of the tree. To iterate on all the subparts of the expression, you have to do so recursively. It allows to handle each subpart specifically (for example subscripts, attribute, etc.), without them getting rendered as strings.

    On the contrary, when flat is true, the whole tree is flattened as a sequence of strings and instances of Names.

Yields:

  • str | Expr

    Strings and names when flat, strings and expressions otherwise.

Iterate on the expression elements.

Parameters:

iterate(*, flat: bool = True) -> Iterator[str | Expr]

Iterate on the expression elements.

Parameters:

iterate ¤

iterate(*, flat: bool = True) -> Iterator[str | Expr]

Iterate on the expression elements.

Parameters:

  • flat ¤

    (bool, default: True ) –

    Expressions are trees.

    When flat is false, this method iterates only on the first layer of the tree. To iterate on all the subparts of the expression, you have to do so recursively. It allows to handle each subpart specifically (for example subscripts, attribute, etc.), without them getting rendered as strings.

    On the contrary, when flat is true, the whole tree is flattened as a sequence of strings and instances of Names.

Yields:

  • str | Expr

    Strings and names when flat, strings and expressions otherwise.

iterate ¤

iterate(*, flat: bool = True) -> Iterator[str | Expr]

Iterate on the expression elements.

Parameters:

  • flat ¤

    (bool, default: True ) –

    Expressions are trees.

    When flat is false, this method iterates only on the first layer of the tree. To iterate on all the subparts of the expression, you have to do so recursively. It allows to handle each subpart specifically (for example subscripts, attribute, etc.), without them getting rendered as strings.

    On the contrary, when flat is true, the whole tree is flattened as a sequence of strings and instances of Names.

Yields:

  • str | Expr

    Strings and names when flat, strings and expressions otherwise.

iterate ¤

iterate(*, flat: bool = True) -> Iterator[str | Expr]

Iterate on the expression elements.

Parameters:

  • flat ¤

    (bool, default: True ) –

    Expressions are trees.

    When flat is false, this method iterates only on the first layer of the tree. To iterate on all the subparts of the expression, you have to do so recursively. It allows to handle each subpart specifically (for example subscripts, attribute, etc.), without them getting rendered as strings.

    On the contrary, when flat is true, the whole tree is flattened as a sequence of strings and instances of Names.

Yields:

  • str | Expr

    Strings and names when flat, strings and expressions otherwise.
