I have to check that file exists or not, and if it does, have to return path to it , the main problem is that os.path.isdir returns only True or False depending on existence, so it seems it does not fit. Any hints? Current schema in my mind  is:
def get_config_path():
    if exists(path1):
        return path1
    if exists(path2):
        return path2
