使用子进程获取返回值 [英] Get a return value using subprocess

问题描述

我希望能够通过脚本的返回值定义一个变量.这是我目前拥有的:

I want to be able to define a variable by the return value of a script. This is what I currently have:

sum_total_earnings_usd = subprocess.call([SCRIPT, "-d", date])

我已经检查了 SCRIPT 的返回值，但是，当我尝试设置这个变量时，它总是返回 0 ( http://docs.python.org/library/subprocess.html#subprocess.call).我将如何运行此脚本并捕获返回值以存储为变量?

I have checked the return value of SCRIPT, however, when I try and set this variable, it always returns 0 ( http://docs.python.org/library/subprocess.html#subprocess.call ). How would I run this script and capture the return value to store as a variable?

推荐答案

使用 <代码>subprocess.check_output() 而不是 subprocess.call().
