我看到了很多關于如何使用 python 的正則表達式在括號之間獲取數據的示例，但沒有一個內部包含某種模式。例如，我有這樣的數據：Overall (each): 37 1/4 × 74 1/2 × 7 7/8 in. (94.6 × 189.2 × 20 dm)Each, 30 x 50 in. (76.2 x 127 dm.)24 3/8 x 14 5/8 x 5 1/8 in. (61.9 x 37.1 x 13 dm)我試圖至少實現的是：(94.6 × 189.2 × 20 dm)(76.2 x 127 dm.)(61.9 x 37.1 x 13 dm)完美的結果如下所示，但我確信這需要第二次分割：94.6, 189.2, 20 76.2, 12761.9, 37.1, 13目前，我正在嘗試這段代碼：regex，但是正如您所看到的，沒有成功捕獲 cm 括號數據。
