Solve the following python programming problem given the following code:
def __call__(self) : 
    args = ['forever', self.foreverCommand, self.script] 
    response = [] 
    def foreverStdOut(msg) : 
        response.append (('FOREVER(%s) OUT> %s' % (self.script, msg))) 
def foreverStdErr(msg) : 
        response.append (('FOREVER(%s) ERR> %s' % (self.script, msg))) 
subprocess = SubprocessRunner.SubprocessRunner (args, foreverStdOut, foreverStdErr, self.environ) 
    subprocess.start () 
    subprocess.wait (self.timeout) 
    subprocess.stop () 
    return '
'.join (args) 

    
    

    Fix the buggy line: return '
'.join (args)
assistant
#Here is Python program to fix the buggy line: return '
.

return '
'.join (response)
