从日志文件中读取，因为它是使用python编写的 [英] Read from a log file as it's being written using python

问题描述

我试图找到一个很好的方法来使用python实时读取日志文件。我想在写一个日志文件时一次处理行。不知何故，我需要继续尝试读取文件，直到创建它，然后继续处理线，直到我终止进程。有没有适当的方法来做到这一点？谢谢。

I'm trying to find a nice way to read a log file in real time using python. I'd like to process lines from a log file one at a time as it is written. Somehow I need to keep trying to read the file until it is created and then continue to process lines until I terminate the process. Is there an appropriate way to do this? Thanks.

推荐答案

你可以尝试这样的东西：

You could try with something like this:

import time

while 1:
    where = file.tell()
    line = file.readline()
    if not line:
        time.sleep(1)
        file.seek(where)
    else:
        print line, # already has newline
