他の方々と同じロジックになってしまいました。

import re

shapes = { 'I': ((0,), (4,)),
           'L': ((0, 0), (3, 1)),
           'O': ((0, 0), (2, 2)),
           'S': ((0, 0, 1), (1, 2, 2)),
           'T': ((1, 0, 1), (2, 2, 2)) }

def solve(data):
    board = {}
    for shift, tetromino in re.findall('(\d+)(.)', data):
        bottom_gaps, heights = shapes[tetromino]
        y = max(board.get(x, 0) - gap
                for x, gap in enumerate(bottom_gaps, int(shift)))
        for x, height in enumerate(heights, int(shift)):
            board[x] = y + height
    return str(max(board.values()))

def test(data, correct):
    answer = solve(data)
    print("%s %s : %s %s" % (("NG", "OK")[answer == correct], answer, correct, data))
