glob（）排除子目录

Question

So I'm working on a script which will go through a bunch of log files looking for strings and server names.

In my testing I was using glob() to create a list of files to troll through.

However, to improve my testing I have copied a log directory from a live system (11gb!) - and things aren't as smooth as they were before.. it looks like glob treats the sub-directories as files, and as such the readlines() is struggling to read them.

I don't care about files in the sub-directories, I just want to scan through the files in the native directory.

I think I can use os.walk() to achieve this, with something like:

logs = next(os.walk('var/opt/server/log/current'))[2]

As opposed to:

logs = glob('/var/opt/server/log/current/*')

Because I'm learning python, I want to make sure I learn things the correct way.. so am I correct in what I'm saying above? Or should I use glob() in a slightly different way to achieve this goal?

使用glob并过滤掉所有目录：

logs = [log for log in glob('/var/opt/server/log/current/*') if not os.path.isdir(log)]
