Rotating list of lists searching for words, only some of the words are appended-CodePudding

I'm trying to get every word in a 15x15 matrix both vertically and horizontally. I get all of the words in the horizontal search. However after I flip I only get some of the words. Is there any obvious flaw I just can't see or is there a less redundant way to do this?

This is code I have currently:

words = []
def stuff(b):
    for line in b:
        word = ""
        for tile in line:
            if tile != "  ":
                word  = tile
            elif tile == "  ":
                if word != "":
                    words.append(word)
                    word = ""

stuff(board)

print_board(board)

t_board = [list(row) for row in zip(*reversed(board))]

print_board(t_board)

stuff(t_board)

print(words)

With the output, as is pretty clear, the single letters i,j,k,l gets appended into the list. However HBA and the bottom letters aren't appended.

I have tried multiple numpy rotations, however these turn the "matrix" into an array of tuples which is not what I'm searching for

CodePudding user response：

It seems like you are trying to flatten data and ignore "empties". You can do this in one line.

words = [cell for row in board for cell in row if cell.strip()]

Below is the "long-form" version of above. Both just iterate over the entire board and store cells that contain more than whitespace.

words = []
for row in board:
    for cell in row:
        if cell.strip():
            words.append(cell)
