RecursiveIteratorIteratornew

RecursiveIteratorIteratornew is a function in Python that creates a new instance of the RecursiveIteratorIterator class. This class is used to iterate over recursive iterators, such as those created by the itertools.chain function or the os.walk function in the os module. The RecursiveIteratorIterator class allows for the traversal of nested iterators, making it easier to work with complex data structures.

The RecursiveIteratorIteratornew function takes two arguments: the iterator to be wrapped and the mode of traversal. The iterator argument is the recursive iterator that you want to iterate over. The mode argument specifies the traversal mode, which can be one of the following:

LEAVES_ONLY: Only the leaf nodes are returned.

SELF_FIRST: The iterator itself is returned first, followed by its children.

CHILD_FIRST: The children of the iterator are returned first, followed by the iterator itself.

Here is an example of how to use RecursiveIteratorIteratornew:

```python

import itertools

import os

# Create a recursive iterator using os.walk

iterator = os.walk('/path/to/directory')

# Create a RecursiveIteratorIterator instance

recursive_iterator = itertools.RecursiveIteratorIteratornew(iterator, itertools.RecursiveIteratorIterator.CHILD_FIRST)

# Iterate over the recursive iterator

for item in recursive_iterator:

print(item)

```

In this example, the RecursiveIteratorIteratornew function is used to create a new instance of the RecursiveIteratorIterator class, which is then used to iterate over the recursive iterator created by os.walk. The mode argument is set to CHILD_FIRST, so the children of the iterator are returned first, followed by the iterator itself.
