搜索特定单词并返回特定行

Question

我在下面的代码中得到了帮助，但需要知道如何让它对所有比赛都这样做。

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)

所以如果我取消注释 'break' 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，它只会显示第一个之后的匹配项。（输出）

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

我怎样才能得到它 return 文件中的所有匹配项（上面的两个输出）？

diskDetails.txt 样本。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（从 ID 开始），因为每个部分有 28 行长。假设关键字在每个部分中。此外，每个部分都由一个空行分隔（如果有帮助的话）。

如何只输出和保存包含'Failed'的部分，并且只包含包含每个部分关键字的行？

Answer 1

更改 #1：将结果附加到列表中。在您重新分配每个循环之前

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

更改 #2：更新我们的过滤器逻辑以遍历结果，因为它现在是列表的列表

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)

希望对您有所帮助！

Answer 2

您使用行 "result = []" 创建了一个空列表，很好。

您重新定义列表 "result" 每次通过 for 循环时使用以下行：结果 = 行 [idx-3:idx+25]

您想在 for 循环中添加到列表 "result" 中，内容如下： result.append(行[idx-3:idx+25])
