问题 I installed pyo on Ubuntu 14.04 without jack and running Python 2.7.I followed the Debian-based installing instructions written in pyo wiki. This was the code i used (it's in the pyo introduction page): from pyo import * s = Server().boot() s.start() a = Sine(mul=0.01).out() And got as result: pyo version 0.6.8 (uses single precision) ALSA lib pcm_dsnoop.c:618:(snd_pcm_dsnoop_open) unable to open slave ALSA lib pcm_dmix.c:1022:(snd_pcm_dmix_open) unable to open slave ALSA lib pcm.c:2239:(snd

问题 I am trying out the pyo for python. I installed the pyo for ubuntu using these commands from the homepage: sudo apt-get install libjack-jackd2-dev libportmidi-dev portaudio19-dev liblo-dev sudo apt-get install libsndfile-dev python-dev python-tk sudo apt-get install python-imaging-tk python-wxgtk3.0 git clone https://github.com/belangeo/pyo.git cd pyo sudo python setup.py install --install-layout=deb --use-jack --use-double Howerver when i try the very first example to Play a sound: >>> from

py文件编译为pyc

什么是pyc文件 pyc是一种二进制文件，是由py文件经过编译后，生成的文件，是一种byte code，py文件变成pyc文件后，加载的速度有所提高，而且pyc是一种跨平台的字节码，是由python的虚拟机来执行的，这个是类似于JAVA或者.NET的虚拟机的概念。pyc的内容，是跟python的版本相关的，不同版本编译后的pyc文件是不同的，2.5编译的pyc文件，2.4版本的python是无法执行的。 为什么需要pyc文件 这个需求太明显了，因为py文件是可以直接看到源码的，如果你是开发商业软件的话，不可能把源码也泄漏出去吧？所以就需要编译为pyc后，再发布出去。当然，pyc文件也是可以反编译的，不同版本编译后的pyc文件是不同的，根据python源码中提供的opcode，可以根据pyc文件反编译出py文件源码，网上可以找到一个反编译python2.3版本的pyc文件的工具，不过该工具从python2.4开始就要收费了，如果需要反编译出新版本的pyc文件的话，就需要自己动手了（俺暂时还没这能力^--^）,不过你可以自己修改python的源代码中的opcode文件，重新编译python，从而防止不法分子的破解。 生成单个pyc文件 python就是个好东西，它提供了内置的类库来实现把py文件编译为pyc文件，这个模块就是 py_compile 模块。 使用方法非常简单，如下所示

问题 I recently installed Pyo, and I entered Python 3.6 and typed from pyo import * s = Server().boot() s.start() sf = SfPlayer("C:\Users\myname\Downloads\wot.mp3", speed=1, loop=True).out() but I get Traceback (most recent call last): File "C:\Python27\pyo.py", line 1, in from pyo import * File "C:\Python27\pyo.py", line 2, in s = Server().boot() NameError: name 'Server' is not defined how do I play the audio file? 回答1: Your own script is called "pyo.py", so when you do from pyo import * it just
