我正在研究python并且我试图执行一个带有1个参数“q”的线程，但是当我试图执行它时发生一个奇怪的异常，这是我的代码：
class Workspace(QMainWindow, Ui_MainWindow):
""" This class is for managing the whole GUI `Workspace'.
Currently a Workspace is similar to a MainWindow
"""
def __init__(self):
try:
from Queue import Queue, Empty
except ImportError:
#from queue import Queue, Empty # python 3.x
print "error"
ON_POSIX = 'posix' in sys.builtin_module_names
def enqueue_output(out, queue):
for line in iter(out.readline, b''):
queue.put(line)
out.close()
p= Popen(["java -Xmx256m -jar bin/HelloWorld.jar"],cwd=r'/home/karen/sphinx4-1.0beta5-src/sphinx4-1.0beta5/',stdout=PIPE, shell=True, bufsize= 4024)
q = Queue()
t = threading.Thread(target=enqueue_output, args=(p.stdout, q))
#t = Thread(target=enqueue_output, args=(p.stdout, q))
t.daemon = True # thread dies with the program
t.start()
# ... do other things here
def myfunc(q):
while True:
try: line = q.get_nowait()
# or q.get(timeout=.1)
except Empty:
print('')
else: # got line
# ... do something with line
print "No esta null"
print line
thread = threading.Thread(target=myfunc, args=(q))
thread.start()
它失败并出现以下错误：
Exception in thread Thread-2:
Traceback (most recent call last):
File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner
self.run()
File "/usr/lib/python2.7/threading.py", line 504, in run
self.__target(*self.__args, **self.__kwargs)
TypeError: myfunc() argument after * must be a sequence, not instance
我不知道发生了什么！请帮忙！
