Question

当我在Windows 7中执行以下脚本时，它会针对这两种情况显示不同的stdout格式。第一个stdout显示内联字符串，第二个显示与在Windows cmd.exe中执行命令相同。我的代码出了什么问题？

import subprocess

process = subprocess.Popen(['dir'], stdout=subprocess.PIPE, shell=True)
stdout = process.communicate()[0]
print('STDOUT:{}'.format(stdout)) #first stdout

subprocess.call('dir', shell=True) #second stdout

first stdout

Answer 1

这类似于具有相同内容的exe文件被调用的事实。您有时可以安装python pip install x或conda pip install x或vs python pip install x。

Python subprocess.Popen（）没有显示正确的stdout subprocess.call（）
