Python-捕获Popen stdout并在控制台上显示? [英] Python - capture Popen stdout AND display on console?

问题描述

我想从通过subprocess.Popen(...)开始的长时间运行的进程中捕获标准输出，因此我将stdout=PIPE用作arg.

I want to capture stdout from a long-ish running process started via subprocess.Popen(...) so I'm using stdout=PIPE as an arg.

但是，由于这是一个长期运行的过程，因此我也想将输出发送到控制台(好像我没有通过管道将其发送给控制台)，以使脚本用户知道它仍在工作.

However, because it's a long running process I also want to send the output to the console (as if I hadn't piped it) to give the user of the script an idea that it's still working.

这有可能吗?

干杯.

推荐答案

在从管道中读取它时，您能否简单地print它?

Can you simply print it as you read it from the pipe?
