The following questions regard how to write subprocess.call to output files. 以下问题与如何将subprocess.call写入输出文件有关。

Question1 问题1

Question2 问题2

Is there away to redirect standard output of subprocess.call() to a string object in python, instead of having to create a file? 是否可以将subprocess.call（）的标准输出重定向到python中的字符串对象，而不必创建文件？ For example, I would like to call the md5sum command, and simply save the results as a string. 例如，我想调用md5sum命令，并将结果简单保存为字符串。 Is there a way to forgo the file making step? 有没有办法放弃文件制作步骤？
