百万年薪python之路 -- 包

包 使用import 和from xx import xx 现有如下结构 bake ├── __init__.py ├── api ├── __init__.py ├── policy.py └── versions.py ├── cmd ├── __init__.py └── manage.py └── db ├── __init__.py └── models.py 我们在bake同级创建一个test.py进行导入policy.py 我们使用模块的import的时候只能将api添加到sys.path的路劲中,我们来看看包使用import导入 import bake.api.policy bake.api.policy.get() 导入的太长了下边使用的时候还需要在重复写一遍,我们可以使用as起别名 import bake.api.policy as p p.get() 这样的操作只支持包,普通的文件夹无效,有人一定在想我把bake拿过来然后一层一层的打开那拿工具就可以了 import bake bake.api.policy.get() 不好使,这样导入是只将policy导入了,有人想怎么将api包下的模块全部导入不要急,先说单独导入的方式 咱们能够使用import进行导入,在来看看from的导入方式 from bake.api import policy policy.get

SVN (Subversion) Problem “File is scheduled for addition, but is missing” - Using Versions

北城余情 提交于 2019-11-27 19:59:52
问题 I'm using Versions for SVN. I attempt to commit and get this message: Commit failed (details follow): '/Users/mike/Sites/mysite.com/astss-cvsdude/Trunk/cart/flashfile.swf' is scheduled for addition, but is missing I suppose this is because I had added files to the repo, and then deleted them via the filesystem. I'd like to have it simply make note of my change, and apply the change to the repo. How can I get around this? 回答1: I'm not sure what you're trying to do: If you added the file via

Python: select one of multiple installed module versions

百般思念 提交于 2019-11-27 19:22:15
On my system, I have several modules installed multiple times. To give an example, numpy 1.6.1 is installed in the standard path at /usr/lib/python2.7/dist-packages , and I have an updated version of numpy 1.8.0 installed at /local/python/lib/python2.7/site-packages/ . The reason I cannot simply remove the old version is that I do not have permissions to change anything on my work computer. I however need to use the new numpy version. I have added /local/python/lib/python2.7/site-packages/ to my PYTHONPATH . Unfortunately, this does not help, since /usr/lib/python2.7/dist-packages is inserted

What do the numbers in a version typically represent (i.e. v1.9.0.1)?

夙愿已清 提交于 2019-11-27 16:42:50
Maybe this is a silly question, but I've always assumed each number delineated by a period represented a single component of the software. If that's true, do they ever represent something different? I'd like to start assigning versions to the different builds of my software, but I'm not really sure how it should be structured. My software has five distinct components. Dillie-O In version 1.9.0.1 : 1 : Major revision (new UI, lots of new features, conceptual change, etc.) 9 : Minor revision (maybe a change to a search box, 1 feature added, collection of bug fixes) 0 : Bug fix release 1 : Build

How do I get the version of an assembly without loading it?

限于喜欢 提交于 2019-11-27 14:37:14
One small function of a large program examines assemblies in a folder and replaces out-of-date assemblies with the latest versions. To accomplish this, it needs to read the version numbers of the existing assembly files without actually loading those assemblies into the executing process. I found the following in this article . using System.Reflection; using System.IO; ... // Get current and updated assemblies AssemblyName currentAssemblyName = AssemblyName.GetAssemblyName(currentAssemblyPath); AssemblyName updatedAssemblyName = AssemblyName.GetAssemblyName(updatedAssemblyPath); // Compare

Java Classloader - how to reference different versions of a jar

 ̄綄美尐妖づ 提交于 2019-11-27 14:00:17
This is a common problem. I'm using 2 libraries A.jar and B.jar and these depend on different versions of the same jar. Let's say that at runtime I need THIS.x.x.x.jar MY.jar -> A.jar -> THIS.1.0.0.jar -> B.jar -> C.jar -> THIS.5.0.0.jar I can compile the specific jar (A.jar/B.jar) against its dependency but at runtime I've to load only 1 version. Which one? Loading only 1 dependency (the latest version) means that my code will probably throw runtime exceptions if the libraries are not Backward Compatible (are there Backward Compatible libraries out there?). Anyway I know that something like

Getting the subversion repository number into code

五迷三道 提交于 2019-11-27 03:34:15
I'd like to implement a way of recording the version of a project within code, so that it can be used when testing and to help track bugs. It seems the best version number to use would just be the current revision number from Subversion. Is there an easy way to hook this number into a (C++ in my case) header file or something, which I can then get at in code? I guess this is a post commit hook or something? Does anyone have any experience of implementing this (with code to share, please?), or can suggest a better alternative? Thanks. While nifty, the revision keyword trick only updates the

Easy way of installing Eclipse plugins on Ubuntu

我是研究僧i 提交于 2019-11-27 02:55:58
问题 I'm running Eclipse (versions 3.6 and 3.5) on Ubuntu and I'm having trouble installing Eclipse plugins. There is an easy way to install eclipse plugins in Eclipse, but this doesn't work for me on Ubuntu! This way only works properly under Windows and Mac OSX. Just like in the tutorial, I create a folder inside my eclipse SDK folder that is named Links . In this folder, I create a file eclipse-cpp-helios-linux-gtk.lnk or eclipse-cpp-helios-linux-gtk.link that contains this line: path=/home

开发一个第三方库的一般性和团队特定规则

我与影子孤独终老i 提交于 2019-11-26 22:36:24
目的 在于将可以重复使用的轮子共用,避免重复造轮子,从而提高生产力。 一般性规则 避免重复造轮子 如果已有思路类似的轮子,请完善之而不是另起炉灶,除非对方的代码已经不堪维护。 谨慎设计 API 规范化类和方法的命名,注意多参函数参数的位置,过时的 API 使用 @Deprecated 注解。 避免引入其他库 当需要依赖第三方库时使用 compileOnly 而不是 implementation ,以避免将第三方库(特别是 support 包)打入其中,将其他第三方库的选择权交给集成者。 尽量用注解代替枚举 注解 @IntDef 、 @StringDef 、 @Interface 和 @Retention 了解一下。 资源文件加上特殊前缀 第三方库的资源文件会跟集成者的相合并,因此需要在命名上独一无二。假定该库为 xxx-yyy ,那么所有资源文件建议加上前缀 xxx_yyy_ 。 提供可插拔依赖的方案 假定该库依赖于一个图片加载库,但不知集成者使用 Picasso 还是 Glide 或者其它图片加载库,这时可以使用 compileOnly 把它们都依赖进来(但不会打进最终的 aar 包),然后在代码中使用 Class.forName() (要捕获异常) 依次检测是否有对应的依赖,有则用之。 将Manifest中的参数变量化,并由 gradle.properties 控制 //
