自从接触Python以来也有几个月了，虽然主要的开发语言还是Java，但对Python也算是情有独钟了。大家也都知道Python为什么会这么火，很大的一个原因就是其有丰富而且强大的库支持，一直以来都是在用别人的库，这次博主也尝试着自己做了一个分发版。
下载地址
制作的是一个命令行下的翻译工具，可以实现英汉中单词，句子的互译。当然了，也是借助了第三方的接口的。
源代码托管在Github上：https://github.com/guoruibiao/MyTranslator
-
pip安装
pip install mytranslator
在pypi官方平台上，也是可以下载到的。如下：
如何制作分发工具呢？
先来看下面的这个文件目录吧。
这个就是比较基础的了，其中必须的文件是setup.py和mytranslator文件夹 其他的不是必须的选项。
其他更加细节性的不妨参考：https://packaging.python.org/distributing/#uploading-your-project-to-pypi
https://wiki.python.org/moin/TestPyPI。
由于全是英文，所以需要耐下心来慢慢的品读咯。
setup.py
我们打包，以及安装Python源码的时候依赖的就是这个文件，里面配置好了安装和使用一个Python库的全部的信息。比较重要，因为官方的解释也比较的详细，就看看人家的官方配置吧，然后咱们按需进行调整即可。

)源码包
这里关系到了包的概念了，通俗的来讲就是包含了一个__init__.py文件的文件夹，大家姑且可以这样理解！然后这个文件夹包含了能够运行我们代码的最小组件，函数库。这样就可以称之为一个包了。
博主这里的小工具比较的简单，如下：
E:\Code\Python\DataStructor\translate\mytranslator 的目录
2016/10/08 15:52 <DIR> .
2016/10/08 15:52 <DIR> ..
2016/09/29 09:12 50 mytranslate.bat
2016/10/08 15:50 1,221 translate.py
2016/10/08 15:51 151 __init__.py
3 个文件 1,422 字节
2 个目录 87,527,870,464 可用字节
其他文件
其他文件是为了让你的用户对这个项目有更加深刻的了解而存在的，跟打包程序关联不大，但是这并不是说不重要。尤其是README.md文件和LICENCE文件，这都是非常的有价值的。LICENCE的概念大家可能比较的陌生，有兴趣的可以参考博主之前转载的一篇文章。http://blog.csdn.net/marksinoberg/article/details/52337214
各种开源协议可以归纳如下：

制作过程
下面谈谈博主制作这个小工具的过程吧。
首先上场的肯定是setup.py了。如下：
# coding:utf-8
from setuptools import setup, find_packages
setup(
name='mytranslator',
description='Simple translator in English and Chinese, easier to use',
url='https://github.com/guoruibiao/MyTranslator',
version='1.0.1',
license='MIT',
packages=find_packages(),
entry_points = {
"console_points": ['trans = mytranslator.translate:main']
},
)然后是LICENCE
MIT License

OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE
SOFTWARE.这样基本上就可以了。
注册
注册之前，最好是在官网上注册一个账号，因为这对今后的上传自己的库会很有帮助。
官网如下： https://pypi.python.org/pypi/
需要注意的就是用户名为ASCII支持的，密码为字母加数字即可。完成之后就可以进行接下来的工作了。
在项目的根目录下输入：
python setup.py register sdist upload
然后会有一个选项，默认选择为数字1，咱们可以按自己的情况来输入。博主由于注册了一个账号于是选择1.
最后出现如下字样，就说明您的库已经上传到了pypi上面了。
running upload
Submitting dist\mytranslator-1.0.1.zip to https://pypi.python.org/pypi
Server response (200): OK
这个时候你会发现自己项目的文件夹下面多了一点东西。基本上如下图所示。
测试
接下来，Python2.7的小伙伴们就可以自己下载博主的这个库了。其实它到底有什么用呢？
其实就是个可以在命令行下面实现英语汉语单词，句子的翻译。而且对于Window尤其优化了编码的支持。详细的可以参考博主之前的文章http://blog.csdn.net/marksinoberg/article/details/52701650

好了，废话不多说。下面介绍一下怎么安装这个库吧。
安装的时候，出现下面的字样，那么恭喜您，成功地安装了博主的库了。

总结
照例，最后一点都是回顾一下这按文章的主要内容。
制作自己的Python分发版库的必要的知识。以及详细的一个流程介绍。
知识点不难，重在尝试，不妨现在就动手，做出你的分发版吧。
