Question

Find the body:

def get_line(board: str, dir: str, col_or_row: int) -> str:
    """Return the characters that make up the specified row, column, or diagonal from the given tic-tac-toe game board.


>>> get_line(4, across, 2)
    XX
    >>> get_line(9, down, 3)
    OOO
    >>> get_line(4, down_diagonal)
    OO
    """

The first parameter refers to a valid tic-tac-toe game board. The second
parameter refers to a string that describes one of the directions: 'down'
'across', 'down_diagonal'] or 'up_diagonal'. The third parameter refers
to a row or column number in the tic-tac-toe game board referred to by
the first parameter. You may assume that the row or column number is
valid for the game board. This function is to return the characters that
make up the specified row (when the second parameter refers to
'across' ), column (when the second parameter is 'down') or diagonal
from the given tic-tac-toe game board. When the second parameter is
'down_diagonal' or 'up_diagonal', the value of the third parameter
should not be used, since the 'down_diagonal' is known to start in the
upper-left corner of the game_board, and the 'up_diagonal') is known to
start in the lower-left corner of the game_board. You must use two of the
functions defined above as helper functions in your solution.
