SE-04 Python Tutorial: Working with Files in Python -Understanding os.walk() method in Python
os.walk() is a Python method used to traverse a directory tree, starting from a given directory and visiting all of its subdirectories and files recursively.
The method takes a single argument, which is the root directory from which the traversal will begin. It returns a generator that yields a 3-tuple for each directory it encounters. The 3-tuple contains the directory path, a list of its subdirectories, and a list of its files.
The os.walk() method automatically handles the traversal of the directory tree, so you don't need to write any recursive code. For each directory, it returns a tuple containing information about the directory itself, as well as a list of its subdirectories and a list of its files.
You can use os.walk() to perform operations on all the files in a directory tree, such as copying, deleting, or processing them. The method is particularly useful when dealing with large and complex directory structures.
