View In Hierarchy

this class provides locals handling common to Module, FunctionDef and ClassDef nodes, including a dict like interface for direct access to locals information

Method	`__contains__`	Check if a local is defined in this scope.
Method	`__getitem__`	The first node the defines the given local.
Method	`__iter__`	Iterate over the names of locals defined in this scoped node.
Method	`add_local_node`	Append a child that should alter the locals of this scope node.
Method	`items`	Get the names of the locals and the node that defines the local.
Method	`keys`	The names of locals defined in this scoped node.
Method	`qname`	Get the 'qualified' name of the node.
Method	`scope`	The first parent node defining a new scope.
Method	`set_local`	Define that the given name is declared in the given statement node.
Method	`values`	The nodes that define the locals in this scoped node.
Class Variable	`locals`	A map of the name of a local variable to the node defining the local.
Method	`_append_node`	append a child, linking it in the tree
Method	`_scope_lookup`	XXX method for interfacing the scope lookup

Inherited from LookupMixIn:

Method	`ilookup`	Lookup the inferred values of the given variable.
Method	`lookup`	Lookup where the given variable is assigned.

def __contains__(self, name): (source)

Check if a local is defined in this scope.

Parameters
name:str	The name of the local to check for.
Returns
bool	True if this node has a local of the given name, False otherwise.

def __getitem__(self, item): (source)

The first node the defines the given local.

Parameters
item:str	The name of the locally defined object.
Raises
`KeyError`	If the name is not defined.

def __iter__(self): (source)

Iterate over the names of locals defined in this scoped node.

Returns
iterable(str)	The names of the defined locals.

def add_local_node(self, child_node, name=None): (source)

Append a child that should alter the locals of this scope node.

Parameters
child_node:NodeNG	The child node that will alter locals.
name:str or None	The name of the local that will be altered by the given child node.

def items(self): (source)

Get the names of the locals and the node that defines the local.

Returns
list(tuple(str, NodeNG))	The names of locals and their associated node.

def keys(self): (source)

The names of locals defined in this scoped node.

Returns
list(str)	The names of the defined locals.

def qname(self): (source)

Get the 'qualified' name of the node.

For example: module.name, module.class.name ...

Returns
str	The qualified name.

def scope(self): (source)

The first parent node defining a new scope.

Returns
Module or FunctionDef or ClassDef or Lambda or GenExpr	The first parent scope node.

def set_local(self, name, stmt): (source)

Define that the given name is declared in the given statement node.

stmt:NodeNG	The statement that defines the given name.

def values(self): (source)

The nodes that define the locals in this scoped node.

Returns
list(NodeNG)	The nodes that define locals.
