Python读取文件并将数据保存到tup

Question

我想读取一个特定的txt文件，从中获取数据并将其写入元组。问题是我不需要文件中的所有数据，只需要特定的数据。 因此文本文件如下所示：

HHSDMSDN1-pool                           1.02T   141G     39     22  2.62M   940K
  **c5t600507680C800000001CBd0   834G   118G**     32     16  2.19M   734K
  **c5t600507680C00352d0   216G  22.3G**      7      5   434K   206K


HHSDMSDN2-pool                           1.09T   308G     12      6   744K  83.8K
  **c5t600507680C800001CDd0   790G   162G**     10      1   617K  12.5K
  **c5t600507680C8000000037Dd0   203G  34.8G**      1      0   123K  10.2K
  **c5t600507680C800000387d0   126G   112G**      0      5  5.36K  80.5K

HHSDMSDN3-pool                           1.13T  33.4G     24     19  1.39M   623K
  **c5t600507680C80002E6000001CFd0   921G  30.8G**     18     11  1.10M   465K
  **c5t600507680C80002E600000203d0   235G  2.63G**      5      8   293K   158K

粗体文本需要进入元组。如果第一个值是string，而下两个值是double/float，则为最佳。你知道吗

所以输出将是

((c5t600507680C800000001CBd0, 834, 118), (c5t600507680C00352d0, 216, 22.3), .....))

有什么想法吗？你知道吗

Answer 1

您只需逐行遍历文件并跟踪您已经看到的内容。你知道吗

# current records

for line in data.splitlines():
    if line.startswith("  c"):

输出：
