Returns the assigned statement (non inferred) according to the assignment type. See astroid/protocols.py for actual implementation.
astroid.nodes.NodeNG.end_col_offset
The end column this node appears on in the source code. Note: This is after the last symbol.
The names of the required arguments. Can be None if the associated function does not have a retrievable signature and the arguments are therefore unknown. This can happen with (builtin) functions implemented in C that have incomplete signature information.
The default values for keyword arguments that cannot be passed positionally. See .args for why this can be None.
The type annotation, passed by a type comment, of each argument. If an argument does not have a type comment, the value for that argument will be None.
The type annotation, passed by a type comment, of each keyword only argument. If an argument does not have a type comment, the value for that argument will be None.
The type annotation, passed by a type comment, of each positional argument. If an argument does not have a type comment, the value for that argument will be None.
astroid.nodes.NodeNG.fromlineno
The first line that this node appears on in the source code. :type: int or None

Get the arguments as dictionary with information about typing and defaults. The return tuple contains a dictionary for positional and keyword arguments with their typing and their default value, if any. The method follows a similar order as format_args but instead of formatting into a string it returns the data that is used to do so.
astroid.nodes.NodeNG._astroid_fields
Node attributes that contain child nodes. This is redefined in most concrete classes.
