PyTreeEntry
One step of an accessor: the child entry of a node of type.
Subclasses fix how the step is taken (__call__) and written
(codify). This base steps with obj[entry].
__init__
__init__(self, entry: 'Any', type: 'type', kind: 'TreeKind') -> None
Initialize self. See help(type(self)) for accurate signature.
codify
codify(self, node: 'str' = '') -> 'str'
The code that takes this step from the expression node.
