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？
答案 0 :(得分：2)
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！
答案 1 :(得分：1)
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]）
