请原谅我的简单问题。我刚刚开始使用Matplotlib,我遇到了一些困难。

我可以在没有问题的情况下运行以下解释器:

>>> from pylab import *  
>>> plot([1,2,3])  
>>> show()  

上面的代码生成了一个漂亮的图表。

但是,如果我将以下代码放在一个文件中并运行它,我会收到一个错误:

#!/usr/bin/env python
# encoding: utf-8

import sys
import os
from pylab import *

plot([1,2,3])
show()

以下是错误消息:

Traceback (most recent call last):

    from pylab import *
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/pylab.py", line 1, in <module>

您的桌面上的文件看起来与标准Python new模块相同:

>>> import new
>>> new
<module 'new' from '/System/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/new.pyc'>

重命名或删除$HOME/Desktop/new.py,然后重试。
