• # Crossword solver

Hi! And again I need help! Now with https://py.checkio.org/ru/mission/crossword-solver/ I don't understant what heppend with assertions. On my PC it work great, function "Check" in mission is working correct, but I cant finish mission.

```def find_words(crossword):
word_list = []
letters = []
for i in range(len(crossword)):
for j in range(len(crossword[i])):
if crossword[i][j] == '.':
dot = (i,j)
letters.append(dot)
letters.sort()
count = 0
while count < len(letters)-1:
word = [letters[count]]
while word[-1][1]+1 == letters[count+1][1]:
word.append(letters[count+1])
count += 1
if count >= len(letters)-1:
break
if len(word)>2:
word_list.append(word)
count+=1
letters.sort(key=lambda x: x[1])
count = 0
while count < len(letters)-1:
word = [letters[count]]
while word[-1][0]+1 == letters[count+1][0]:
word.append(letters[count+1])
count += 1
if count >= len(letters)-1:
break
if len(word)>2:
word_list.append(word)
count+=1
word_list.sort(key=lambda x: len(x), reverse=True)
return (word_list, letters)
