|
Read as: `[traverse_obj(obj, branch) for branch in branches]`.
|
|
|
- `function`: Branch out and return values filtered by the function.
|
|
|
Read as: `[value for key, value in obj if function(key, value)]`.
|
|
|
For `Sequence`s, `key` is the index of the value.
|
|
|
For `Iterable`s, `key` is the enumeration count of the value.
|
|
|
For `re.Match`es, `key` is the group number (0 = full match)
|
|
|
as well as additionally any group names, if given.
|
|
|
- `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.
|
|
|
|
|
|
@params paths Paths which to traverse by.
|
|
|
Keyword arguments:
|
|
|
@param default Value to return if the paths do not match.
|
|
|
If the last key in the path is a `dict`, it will apply to each value inside
|
|
|
the dict instead, depth first. Try to avoid if using nested `dict` keys.
|
|
|
@param expected_type If a `type`, only accept final values of this type.
|
|
|
If any other callable, try to call the function on each result.
|
|
|
If the last key in the path is a `dict`, it will apply to each value inside
|
|
|
the dict instead, recursively. This does respect branching paths.
|
|
|
@param get_all If `False`, return the first matching result, otherwise all matching ones.
|
|
|
@param casesense If `False`, consider string dictionary keys as case insensitive.
|
|
|
|
|
|
The following are only meant to be used by YoutubeDL.prepare_outtmpl and are not part of the API
|
|
|
|
|
|
@param _is_user_input Whether the keys are generated from user input.
|
|
|
If `True` strings get converted to `int`/`slice` if needed.
|
|
|
@param _traverse_string Whether to traverse into objects as strings.
|
|
|
If `True`, any non-compatible object will first be
|
|
|
converted into a string and then traversed into.
|
|
|
The return value of that path will be a string instead,
|
|
|
not respecting any further branching.
|
|
|
|
|
|
|
|
|
@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.
|
|
|
If a path ends on a `dict` that result will always be a `dict`.
