Possible Duplicate: How to find the mime type of a file in python? I want to detect the type of a file, but I don't want to look at the extension because it may be incorrect.

I had installed Anaconda and it had already been embedded with some packages like matplotlib. But in my python idle shell, if I type in "import matplotlib.pyplot as plt" it returns No module named 'matplotlib' I assume the path directory where python calls in matplolib is different from where anaconda installed it. Any hint to solve this situation?
我已经安装了Anaconda，它已经嵌入了一些像matplotlib这样的软件包。 但是在我的python闲置shell中，如果输入“import matplotlib.pyplot as plt”，它将返回No module named'matplotlib' 我假设python在matplolib中调用的路径目录与anaconda安装目录的路径目录不同。 任何暗示来解决这种情况？

This question already has an answer here: python matplotlib framework under macosx? 8 answers Problem Cause In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There is Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os. I resolve this issue

I am new to python and one of the problems I am working on is to plot 500 pairs of successive random numbers. I have a formula that generates the numbers seen below: x-axis >>> a=128 >>> c=0 >>> m=509 >>> n=500 >>> seed = 10 >>> for i in range (1,n): new_seed=(a*seed+c)%m seed = new_seed print new_seed y-axis >>> a=2
我是python的新手，我正在处理的其中一个问题是绘制500对连续的随机数。 我有一个公式可以产生下面显示的数字： x轴 >>> a=128 >>> c=0 >>> m=509 >>> n=500 >>> seed = 10 >>> for i in range (1,n): new_seed=(a*seed+c)%m seed = new_seed print new_seed y轴 >>> a=269 >>> c=0 >>> m=2048 >>> n=500 >>
I want to write an application to video capture from web-cams in linux. Is there a python library to do that? You should look at Gstreamer and its Python bindings. Here http://pygstdocs.berlios.de/pygst-tutorial/webcam-viewer.html is some sample code to display video from a webcam. To record the video you would have to change the pipeline definition from autovideosink to an encoder and files
我想写一个应用程序来从Linux中的网络摄像头捕获视频。 有没有一个Python库来做到这一点？ 你应该看看Gstreamer及其Python绑定。 这里http://pygstdocs.berlios.de/pygst-tutorial/webcam-viewer.html是一些示例代码，用于显示来自网络摄像头的视频。 要记录视频，您必须将管道定义从autovideosink更改为编码器和文件链接。 你可以看看WebCamsPy ，它似乎正在做你在问什么。 此外，请参阅相关问题，该问题更常用于Windo
我想建立一个PayPal捐款箱，并使用他们的IPN协议来监测捐赠何时到来。文档非常复杂，充满了我不感兴趣的功能。是否有一个简短的代码片段 - 理想情况是在Python中 - 这说明如何连接到PayPal，永久循环，并且每次捐赠时都打印“刚刚获得5美元”？ Actually, with IPNs it's the other way around. PayPal posts a notification to your server via HTTP POST when a payment is made. You therefore need to make a CGI script
我想建立一个PayPal捐款箱，并使用他们的IPN协议来监测捐赠何时到来。文档非常复杂，充满了我不感兴趣的功能。是否有一个简短的代码片段 - 理想情况是在Python中 - 这说明如何连接到PayPal，永久循环，并且每次捐赠时都打印“刚刚获得5美元”？ 其实，与IPNs是相反的。 付款后，PayPal会通过HTTP POST向您的服务器发送通知。 因此，您需要制作一个CGI脚本或服务器来接收这些帖子，检查其有效性并对其进行处理。 PHP示例代码可
