processing安装python模式

① 为什么我的processing 的python模式用不了import函数

应该是你的python 环境里没有安装 import 所需的第三方库
你可以用pip list 命令检查是不是没有安装，没有的话就要先安装所需的第三方库

② 如何安装python的第三方模块

通过pip来安装python模块

安装 easy_install pip

③ Python模块常用的几种安装方式

几种情况
1.预编译好的exe文件，直接双击安装即可
2.rar等包，解压后，从命令行中cd到解压的目录，通过setup.py文件来安装模块：
命令为，python setup.py install （若python未配置环境变量，则需要给python的安装绝对路径，如： C:/python27/python setup.py install）
备注：一般第三方模块安装好后，在 python安装路径/Lib/site-package下可以看得到

④ python中 multiprocessing 和 processing两个模块有什么区别

processing貌似是基于python传统的threading模块
虽然功能功能挺多但还是有GIL的限制
而multiprocessing貌似脱离了GIL
虽然功能一样但是对多CPU的利用率提高了

⑤ 如何在Windows系统中安装Python

Python安装

这里以Windows系统为例，其他操作系统自己找下别的教程吧！

python官网下载

之后输入【exit()】即可退出，这里（）是在英文输入模式下输入.

OK，python安装完成。

⑥ 安装好python后,有几种打开方式

（1）利用Win的操作系统的：命令行工具 cmd.exe


Win + R  调出运行对话框，然后输入cmd，即可调出“命令提示符对话框”

或者 在菜单中店家附件中的命令提示哭选项，也可以调出然后输入python，即可进入python的运行模式，输入quit（），或者exit（）即可退出


（2）通过调用Win环境下的安装的IDLE（GUI）来启动python

IDLE是开发python程序的基本IDE（集成开发环境），具备基本的IDE的功能，是非商业Python开发的不错的选择。当安装好python以后，IDLE就自动安装好了，不需要另外去找。
（3）按照python 的语法格式编写代码，并保存为文件。然后通过Win下的命令行，通过python命令执行该python文件即可。

如 hello.py 文件

python hello.py


（4）可以在第二中方法上，通过新建一个python的编辑对话框，然后进行python语句的编写，然后保存为.py 的文件

通过在新建的文件上：按下快捷键F5即可运行该程序。


（5）通过将python的开发集成到较大规模的项目开发的继承开发环境（IDE）中，如eclipse，vs2010.

⑦ python 第三方库怎么安装

【方法一】: 通过setuptools来安装python模块
首先下载
NOTE: 最好下载个setuptools，本人是15.2版本，里面包含了ez_setup
运行 python ez_setup.py
D:\work\installation\setuptools-15.2\setuptools-15.2>python ez_setup.py > 1.txt
Extracting in c:\users\admini~1\appdata\local\temp\tmpbxikxf
Now working in c:\users\admini~1\appdata\local\temp\tmpbxikxf\setuptools-15.2

运行 easy_install py
D:\work>easy_install py #py 为第三方库文件
Searching for py
