In Python 2, it used to return a list of tuples of the size equal to the shortest of the input iterables. Also, an empty zip () call would get you an empty list. Whereas in Python 3, the zip () is reimplemented to return an iterator. Upon traversing, it gets you the tuple from the zipped result one by one. The recursive Python function print_movie_files takes two arguments: the directory path to search. Then it gets a list of all files and folders in this directory using the os.listdir method. We use a for loop to work on the list,, check whether the filepath is a normal file or directory using the os.path.isfile method.
