输出： imconfig-i th0-c 01-h-a

示例：（在命令提示符中）

c:/python34> python ssm9.py
 imconfig -i th0 -c 01 - h -a

c:/python34> imconfig -i th0 -c 01 -h -a 
/// i want something like that means the above printed value redirect here. but in linux terminal window

Answer 1

我写了这样一个示例代码

vivek@vivekUbuntu:~$ cat sample.py
#! /usr/bin/python
import socket
hostname = socket.gethostname()

def getPingCommand(host):
    return "ping %s" %host

print getPingCommand(hostname)

然后像这样执行：

vivek@vivekUbuntu:~$ `python sample.py`
PING vivekUbuntu (127.0.1.1) 56(84) bytes of data.
64 bytes from vivekUbuntu (127.0.1.1): icmp_seq=1 ttl=64 time=0.020 ms

甚至S0III0s提到的选项也是正确的。这对我很有用。你知道吗

Answer 2

`python ssm9.py`

或者

$(python ssm9.py)

或者

eval `python ssm9.py`

或者

eval $(python ssm9.py)

应该都管用。你知道吗

（你可以这样试试：）

> $(echo "echo test")
test
