In plain python, you need to use something along the lines of this:

from subprocess import check_output
check_output("ls", shell=True)

In IPython, you can run either of those commands or a general shell command by starting off with ! . For example

! echo "Hello, world!" > /tmp/Hello.txt

If you're using python interactively, you would almost certainly be happier with IPython.

如果您打算在调用命令（ls，pwd，...）时交互使用Python shell，请查看iPython。
