That has consequences related to another keyword in the question: " add them into a list ": In pre Python 2. In Python 2. Wiki]: Generators - courtesy of [Python 3]: The yield statement - was introduced. The example below illustrates the differences on [Python 3]: map function, iterable, CristiFati's answer - last notes from item 4.
I didn't bother to make it recursive, but starting from the existing code, that would be a fairly trivial task Everything is doable on Win as well, the data libraries, functions, structs, constants, I must also mention that I didn't try to increase recursionlimit because I have no experience in the area how much can I increase it before having to also increase the stack at OS level , but in theory there will always be the possibility for failure, if the dir depth is larger than the highest possible recursionlimit on that machine The code samples are for demonstrative purposes only.
For production , error handling should be added as well Other approaches: Use Python only as a wrapper Everything is done using another technology That technology is invoked from Python The most famous flavor that I know is what I call the system administrator approach: Use Python or any programming language for that matter in order to execute shell commands and parse their outputs Some consider this a neat hack I consider it more like a lame workaround gainarie , as the action per se is performed from shell cmd in this case , and thus doesn't have anything to do with Python.
Also, I deliberately used os.

What is the added value of using an external dependency when all you need is already in the language? MarredCheese MarredCheese Vinodh Krishnaraju Vinodh Krishnaraju 1 1 silver badge 7 7 bronze badges.

In the above methods, the python code was returning all the items in the current directory irrespective of their nature. We can extract only the files using the path. In the above code snippet, List Comprehension is used to filter out only those items that are actually a file.
Another key thing to note here is that, the above code does not work for other directories as the variable 'f' is not an absolute path, but a relative path to the current directory. In order to print the files inside a directory and its subdirectories, we need to traverse them recursively. With the help of the walk method, we can traverse each subdirectory within a directory one by one.
The os. There are three iterators used for going through the output of os. The join method is used to concatenate the file name with its parent directory, providing us with the relative path to the file. Similar to the above procedure, glob can recursively visit each directory and extract all items and return them. Since we wish to extract only the files in the complete directory, we filter out the files using the isfile function used before.
