import os

root = "."

# The following lists all files immediately in the root,
# i.e., not in its subdirectory
for fname in next(os.walk(root))[2]:
    print(os.path.join(root, fname))

# For python 3x, use
# import pathlib
# pathlib.PurePath(root, fname)

# The following lists all files in the root and its subdirectories
for path, dirs, files in os.walk(root):
    for fname in files:
        print(os.path.join(path, fname))
