我正在尝试运行第二页上显示的代码:

http://ocw.mit.edu/courses/electrical-engineering-and-computer-science/6-00-introduction-to-computer-science-and-programming-fall-2008/video-lectures/lecture-20/ lec20.pdf

在代码的底部,您必须添加以下行:

simFlips(100,100)

show()

这是我在ubuntu上运行时遇到的错误:

Traceback (most recent call last):
  File "coin.py", line 36, in <module>
    simFlips(100,100)
  File "coin.py", line 16, in simFlips
    diffs.append(abs(heads - tails))
AttributeError: 'numpy.ndarray' object has no attribute 'append'

请告诉我我做错了什么给了我最后一个错误.提前致谢!
