Parameters:
item:Any
any object that can be recursively iterate
children_parents_method:str
name of the method that gets the children/parents item
(default="children")
delete_duplicates:bool=True
Useful if you use flatten_all=True
default=True)
flatten_all:bool=False
Returns all items as a flattened list
default=False)
normalize_children_list:bool=False
Useful if you don't want to flatten the output and want the same length for
every children list (e.g. for creating a DataFrame)
(default=False)
Returns:
readyitems:list
