if statement is not saving variable data #Python

I GOT THE ANSWER OF M POST THANKS FOR HELPING ME AND WISH OTHERS LEARN FROM MY MISTAKES GOOD LUCK ALL

I Have Folders that take in .meta files and want to save each filename in variable , all folder take in the same meta file name but I added the folder name into the file with hypthen means -> foldername + '-' + filename

and want to print the file name in each folder into file that I created in specific driver and used os.chdir() to load into file path

so when im going to print each folder meta file name into this file its not saving the var

    for dirpath, dirnames, files in os.walk('.') :
        print('loop')
        for file in files :
            print('file')
            if file.endswith('.meta'):
                print('meta')
                METAPath = os.path.abspath(os.path.join(dirpath, file))
                METABase = os.path.basename(dirpath)
                if True :
                    if file.startswith(METABase + '-' + 'handling'):
                        HandlingFile = "'" + file + "'"
                        return HandlingFile
                    elif file.startswith(METABase + '-' + 'vehicles'):
                        VehiclesFile = "'" + file + "'"
                        return VehiclesFile
                    elif file.startswith(METABase + '-' + 'carvariations'):
                        CarVariationsFile = "'" + file + "'"
                        return CarVariationsFile
                    elif file.startswith(METABase + '-' + 'carcols'):
                        CarcolsFile = "'" + file + "'"
                        return CarcolsFile
                    elif file.startswith(METABase + '-' + 'dlctext'):
                        DLCTextFile = "'" + file + "'"
                        return DLCTextFile
                    print(HandlingFile, VehiclesFile ,CarVariationsFile ,CarcolsFile ,DLCTextFile)

Error :
