python - 从文本文件python中提取一行

Question

嗨，我是 python 新手，真的不知道从哪里开始，所以这里

我有一个文本文件的以下部分，该文件要长得多，如果文件中的一行以“错误”开头，我想从中挑选一些信息，那么我想在另一个文本文件中打印该信息

1 warning message 
Warning 1 - Loop End (SGLoopControl2) - errors were encountered during run
2 error messages
Error 1 - 0952 RHFDShaftTorq Not Found in asd22961ck99_
Error 2 - Multi-column property values processing halted at loop iteration 2 (run failed)

非常感谢任何帮助。

Answer 1

with open('path_to_file', 'rb') as f:
    for line in f:
        if line.startswith('Error'):
            do_something_with_line(line)

You might also want to strip the line with line.strip().
