如何对文本文件执行数据清理

Question

我有一个文本文件，里面有很多行，包括单词和数字，下面是一个例子：

2021-12-06 05:07:09.266 INFO: Additional  ID 1638301749791
2021-12-06 05:07:09.266 INFO: Found

2021-12-06 05:07:09.267 INFO: disabled; computing power weight factor factor 19025.
2021-12-06 05:07:10.041 INFO: Wrote big factor 0.3568357342, Classificationfactortype-fail
2021-12-06 05:07:10.042 DEBUG: Duiu.0.0.2588650814
2021-12-06 05:07:10.743 INFO: Wrote .3254806495

我的问题是，我如何保持行中有特定单词"；分类因子类型失败"以及"；ObjectStatus ok"；，并删除所有其他行？我想把新的文本文件保存在目录中。

这是我写的代码：

ans = []
with open('test. txt') as rf:
for line in rf:
line = line.strip()
if "Classificationfactortype-fail" in line or "ObjectStatus-ok" in line:
ans.append(line)
with open('extracted_data.txt', 'w') as wf:
for line in ans:
wf.write(line)

Answer 1

如果每一行都以时间代码开头，那么str.startswitch((将不起作用。

你可以简单地做：

if "Classificationfactortype-fail" in line or "ObjectStatus-ok" in line:
ans.append(line)

在你的第一个循环中。
