Python - get list of all files from a folder (with more options)

Is exist some usual way to enumerate all files (and optionally folders, optionally recursive with sub dirs) inside a given folder? So I pass a folder path and get list of resulting full paths.

If you show how to exclude all read-only and all hidden files from this result, it'd be better. So input params:

You should probably look into os.walk and os.access.

For the actual implementation you can do something like:

import os

def get_files(path, option_dirs, option_subdirs, option_no_ro, option_no_hid):
    outfiles = []
    for root, dirs, files in os.walk(path):
        if option_no_hid:
            # In linux, hidden files start with .
            files = [ f for f in files if not f.startswith('.') ]
        if option_no_ro:
            # Use os.path.access to check if the file is readable
            # We have to use os.path.join(root, f) to get the full path
            files = [ f for f in files if os.access(os.path.join(root, f), os.R_OK) ]
        if option_dirs:
            # Use os.path.join again
            outfiles.extend([ os.path.join(root, f) for f in files ])
        else:
            outfiles.extend(files)
        if not option_subdirs:
            # If we don't want to get subdirs, then we just exit the first
            # time through the for loop
            return outfiles
    return outfiles
