def sentences_by_length(file_name):

words_counter = {}

with open(file_name) as f:

for line in f:

words_len = len(line.split())

if words_len in words_counter:

words_counter.setdefault(words_len, []).append(line)

else:

words_counter[words_len] = [line]

return words_counter

for k, v in sentences_by_length("code.txt").items(): print(f"{k}: {v}")
