从使用 python 写入的日志文件中读取 [英] Read from a log file as it's being written using python

问题描述

我正在尝试找到一种使用 python 实时读取日志文件的好方法.我想在写入时一次处理一个日志文件中的行.不知何故，我需要继续尝试读取文件，直到它被创建，然后继续处理行，直到我终止进程.有没有合适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

你可以试试这样的:

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
