What is OS walk?
os. walk returns a generator, that creates a tuple of values (current_path, directories in current_path, files in current_path). Every time the generator is called it will follow each directory recursively until no further sub-directories are available from the initial directory that walk was called upon.
How can you protect vs path traversal attacks?
The most effective way to prevent file path traversal vulnerabilities is to avoid passing user-supplied input to filesystem APIs altogether. Many application functions that do this can be rewritten to deliver the same behavior in a safer way.

OS. walk() generate the file names in a directory tree by walking the tree either top-down or bottom-up. For each directory in the tree rooted at directory top (including top itself), it yields a 3-tuple (dirpath, dirnames, filenames). root : Prints out directories only from what you specified.
What is OS in Python?

How does the walk method work in Python?
Python method walk () generates the file names in a directory tree by walking the tree either top-down or bottom-up. top − Each directory rooted at directory, yields 3-tuples, i.e., (dirpath, dirnames, filenames) topdown − If optional argument topdown is True or not specified, directories are scanned from top-down.
How does a directory tree work in Python?
