Question

我获得了以下代码的帮助，但需要知道如何在所有比赛中都做到这一点。

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“中断”，则仅显示第一个（如所述）（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，它只会在第一个之后显示一个匹配项。（输出）

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

如何获取它以返回文件中的所有匹配项（以上两个输出）？

diskDetails.txt示例。该文件可能包含4-8个部分，如下所示。我没有包括每个部分的每一行（以ID开头），因为每个部分长28行。假设关键字在每个部分中。同样，每个部分都用空白行分隔（如果有帮助的话）。

如何仅输出和保存包含“失败”并且仅包含包含每个部分的关键字的行的部分？

Answer 1

更改1：将结果追加到列表中。在每个循环上重新分配之前

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

更改2：更新过滤器逻辑以遍历结果，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：遍历结果并写入文件

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

希望这会有所帮助！

Answer 2

您用“结果= []”行创建了一个空列表，这很好。

您重新定义列表“结果”，每次通过for循环使用以下行：结果=线[idx-3：idx + 25]

您要使用以下内容将for循环添加到列表“结果”： result.append（lines [idx-3：idx + 25]）

搜索特定单词并返回特定行
