问题描述
我最多有8个独立的Python进程在共享文件夹中创建临时文件。然后,我希望控制过程将所有临时文件按一定顺序附加到一个大文件中。
I have up to 8 seperate Python processes creating temp files in a shared folder. Then I'd like the controlling process to append all the temp files in a certain order into one big file. What's the quickest way of doing this at an os agnostic shell level?
推荐答案
仅使用简单的文件IO:
Just using simple file IO:
# tempfiles is a list of file handles to your temp files. Order them however you like
f = open("bigfile.txt", "w")
for tempfile in tempfiles:
f.write(tempfile.read())
这与操作系统无关。它也很简单,性能应该和使用其他任何东西一样好。
That's about as OS agnostic as it gets. It's also fairly simple, and the performance ought to be about as good as using anything else.
