Safely traverse nested `dict`s and `Sequence`s
"value"
Each of the provided `paths` is tested and the first producing a valid result will be returned.
+ The next path will also be tested if the path branched but no results could be found.
+ Supported values for traversal are `Mapping`, `Sequence` and `re.Match`.
A value of None is treated as the absence of a value.
The paths will be wrapped in `variadic`, so that `'key'` is conveniently the same as `('key', )`.
The keys in the path can be one of:
- `None`: Return the current object.
- - `str`/`int`: Return `obj[key]`.
+ - `str`/`int`: Return `obj[key]`. For `re.Match`, return `obj.group(key)`.
- `slice`: Branch out and return all values in `obj[key]`.
- `Ellipsis`: Branch out and return a list of all values.
- `tuple`/`list`: Branch out and return a list of all matching values.
- `dict` Transform the current object and return a matching dict.
Read as: `{key: traverse_obj(obj, path) for key, path in dct.items()}`.
- `tuple`, `list`, and `dict` all support nested paths and branches
+ `tuple`, `list`, and `dict` all support nested paths and branches.
@params paths Paths which to traverse by.
@param default Value to return if the paths do not match.
@returns The result of the object traversal.
If successful, `get_all=True`, and the path branches at least once,
then a list of results is returned instead.
+ A list is always returned if the last path branches and no `default` is given.
