如何在 os.system 命令中添加空格

Question

我正在尝试在 os.system 命令的每一行的开头添加一些空格

example

os.system('pip install pyinstaller')

然后我明白了

但我想在每行中添加一些空格以显示视觉效果，以便与其余部分相匹配我已经查了很多次了，我已经搜索了几个小时，但我找不到它，请帮忙

您可以在命令中将输出通过管道传输到 sed：

os.system("pip install pyinstaller | sed 's/^/  /'")

尽管如评论所述，更好的解决方案是使用 subprocess.Popen()。然后你可以读取命令的输出，以任何你想要的方式对其进行转换，然后将修改后的输出写入终端。
