With Python, you can also inspect the content of a directory. I'll show you two ways of doing this:

# files/listing.py
import os

with os.scandir('.') as it:
    for entry in it:
        print(
            entry.name, entry.path,
            'File' if entry.is_file() else 'Folder'
        )

This snippet uses os.scandir, called on the current directory. We iterate on the results, each of which is an instance of os.DirEntry, a nice class that exposes useful properties and methods. In the code, we access a subset of those: name, path, and is_file(). Running the code yields the following (I omitted a few results for brevity):

$ python listing.py
fixed_amount.py ./fixed_amount.py File
existence.py ./existence.py File
...
ops_example ./ops_example Folder
...

A more powerful way to scan a directory tree is given to us by os.walk. Let's see an example:

# files/walking.py
import os

for root, dirs, files in os.walk('.'):
    print(os.path.abspath(root))
    if dirs:
        print('Directories:')
        for dir_ in dirs:
            print(dir_)
        print()
    if files:
        print('Files:')
        for filename in files:
            print(filename)
        print()

Running the preceding snippet will produce a list of all files and directories in the current one, and it will do the same for each sub-directory.
