搜索特定单词并返回特定行

Question

我在下面的代码上得到了帮助，但我需要知道如何让它在所有的比赛中完成。

result = []
# 1. Search for the first failed entry:
with open('diskDetails.txt', 'r') as f:
    lines = f.readlines()
    for idx, line in enumerate(lines):
        if ': Failed' in line:
            result = lines[idx-3:idx+25]  # save lines from 'ID' to 'Sub Vendor'
            #break  # only the first match

# 2. Filter result:
keywords = ('ID', 'State', 'Capacity', 'Product ID', 'Serial No.')
result = list(filter(lambda l: str(l).startswith(keywords), result))

# 3. Save result:
with open('dataFinal.txt', 'wt') as f:
    f.writelines(result)

因此，如果我取消注释的“中断”，它只显示第一个(如前所述)(输出)

ID                              : 0:1:2
State                           : Failed
Capacity                        : 558.38 GB (599550590976 bytes)
Product ID                      : ST3600057SS
Serial No.                      : 6SL7YFWF

如果我注释掉了，它只显示第一个之后的匹配。(产出)

ID                              : 0:1:5
State                           : Failed
Capacity                        : 558.38 GB (599550590976 bytes)
Product ID                      : ST3600057SS
Serial No.                      : 6SLAWWHQ

如何让它返回文件中的所有匹配(上述两个输出)？

diskDetails.txt样品该文件可能包含4-8节，如下所示。我没有包括每个部分的每一行(从ID开始)，因为每个部分都有28行长。假设关键字在每个部分中。另外，每个部分都由一个空行分隔(如果这有帮助的话)。

如何输出和保存仅包含“失败”和只包含包含每个节的关键字的行的部分？

Answer 1

更改1:将结果追加到列表中。在你重新分配每个循环之前

if ': Failed' in line:
    result.append(lines[idx-3:idx+25])

更改2:更新筛选逻辑以循环结果，因为它现在是列表列表

results = list(filter(lambda l: str(l).startswith(keywords), r) for r in result)

更改#3:循环结果并写入文件

with open('dataFinal.txt', 'wt') as f:
    for result in results:
        f.writelines(result)

希望这能有所帮助！

Answer 2

您创建了一个空列表，其行为"result = []"，这很好。

您将重新定义列表“结果”，每一次都使用以下行遍历for-循环: result = linesidx-3:idx+25

您希望在for-循环中添加类似于: result.append(linesidx-3:idx+25)的列表“结果”。
