Solve the following python programming problem given the following code:
def _download(out_file, decompress, disambig, url, verbose = True) : 
    if (decompress and (out_file == DEFAULT_OUT_FILE)) : 
        out_file = DEFAULT_OUT_FILE [: (- 4)] 
if disambig : 
        url = DISAMBIGUATED_CORPORA_URL_BZ2 
if verbose : 
        print (('Creating %s from %s' % (out_file, url))) 
with open (out_file, 'wb') as out : 
        if verbose : 
            def on_chunk() : 
                sys.stdout.write ('.') 
                sys.stdout.flush () 
else : 
            on_chunk = (lambda : None) 
_download_file (url, out, decompress, on_chunk = out) 
if verbose : 
        print ('
Done.')
