尝试分析简单程序时出现 Python-Hotshot 错误

我试图学习如何使用 hotshot 分析一个简单的 python 程序，但遇到了一个奇怪的错误，

import sys
import hotshot
def main(argv):
  for i in range(1,1000):
    print i

if __name__ == "__main__":
  prof = hotshot.Profile("hotshot_edi_stats")
  b,c = prof.runcall(main(sys.argv))
  prof.close()

并且输出，

.
.

995
996
997
998
999
Traceback (most recent call last):
  File "t.py", line 9, in <module>
    b, c = prof.runcall(main(sys.argv))
  File "/usr/lib/python2.5/hotshot/__init__.py", line 76, in runcall
    return self._prof.runcall(func, args, kw)
TypeError: 'NoneType' object is not callable

有人知道为什么会发生这种情况吗？在我看来，这似乎是热点分析器本身的问题。或者，人们对分析 python 程序的其他方法有建议吗？

谢谢！

I was trying to learn how to profile a simple python program using hotshot, but am facing a weird error,

import sys
import hotshot
def main(argv):
  for i in range(1,1000):
    print i

if __name__ == "__main__":
  prof = hotshot.Profile("hotshot_edi_stats")
  b,c = prof.runcall(main(sys.argv))
  prof.close()

and the output,

998
999
Traceback (most recent call last):
  File "t.py", line 9, in <module>
    b, c = prof.runcall(main(sys.argv))
  File "/usr/lib/python2.5/hotshot/__init__.py", line 76, in runcall
    return self._prof.runcall(func, args, kw)
TypeError: 'NoneType' object is not callable

Would anyone know why this happens? It looks to me like a problem with the hotshot profiler itself. Alternatively, do people have suggestions on other methods to profile python programs?

Thanks!
