如何將字符串或列表對象作爲參數傳遞到結構？

Question

我的問題是，我的字符串是幾個字，實際上包含'字符...所以我在如何傳遞我想要的字符串的損失。

我試圖做的事：

fab -H myhost.serv.com execute:"nc -zw1 159.1.1.1 9988 | gawk '{print $7}'","nc -zw1 159.1.1.2 9988 | gawk '{print $7}'" 

然而，這種吐出：

Executing task 'execute' 
Traceback (most recent call last): 
    File "/usr/lib/python2.7/dist-packages/fabric/main.py", line 743, in main 
    *args, **kwargs 
    File "/usr/lib/python2.7/dist-packages/fabric/tasks.py", line 368, in execute 
    multiprocessing 
    File "/usr/lib/python2.7/dist-packages/fabric/tasks.py", line 264, in _execute 
    return task.run(*args, **kwargs) 
    File "/usr/lib/python2.7/dist-packages/fabric/tasks.py", line 171, in run 
    return self.wrapped(*args, **kwargs) 
    File "/usr/lib/python2.7/dist-packages/fabric/decorators.py", line 175, in real_decorator 
    @wraps(func) 
    File "/usr/lib/python2.7/functools.py", line 33, in update_wrapper 
    setattr(wrapper, attr, getattr(wrapped, attr)) 
AttributeError: 'str' object has no attribute '__module__' 

有沒有解決這個辦法嗎？我從一個Python腳本調用它：

fabcmd = 'fab -H ' + ','.join(servlist) + ' execute:' 
for cmd in commands: 
    fabcmd += "\"{}\",".format(cmd) 
print fabcmd 
subprocess.call(fabcmd) 

如果有傳我的命令列表對象結構的方式，這實際上是理想的..所以，我可能只是做類似...

fabcmd = 'fab -H ' + ','.join(servlist) + ' execute:' + commands`

顯然，答案是這裏無關的東西上面貼 - 我有裝飾訂購錯誤的，我fabfile.py：

原始

from fabric.api import parallel, task 

@parallel 
@task 
def execute(*args): 
    print args 

修改

from fabric.api import parallel, task 

@task 
@parallel 
def execute(*args): 
    print args 

我不知道爲什麼這個要緊......所以，如果有人可以解釋，那簡直太棒了。
