When building an end-to-end project, our primary goals are: 在我们开始下载和探索数据之前，先想一想将如何构造项目是很重要的。当建立端到端项目时，我们的主要目标是： -- Creating a solution that works - 创建一个可行解决方案 -- Having a solution that runs quickly and uses minimal resources - 有一个快速运行且占用最小资源的解决方案 -- Enabling others to easily extend our work - 容易可扩展 -- Making it easy for others to understand our code -- 容易理解的代码 -- Writing as little code as possible +- 写容易理解的代码 - 写尽量少的代码 -In order to achieve these goals, we’ll need to structure our project well. A well structured project follows a few principles: - -- Separates data files and code files. -- Separates raw data from generated data. -- Has a README.md file that walks people through installing and using the project. -- Has a requirements.txt file that contains all the packages needed to run the project. -- Has a single settings.py file that contains any settings that are used in other files. - - For example, if you are reading the same file from multiple Python scripts, it’s useful to have them all import settings and get the file name from a centralized place. -- Has a .gitignore file that prevents large or secret files from being committed. -- Breaks each step in our task into a separate file that can be executed separately. +为了实现这些目标，需要对我们的项目进行良好的构造。一个结构良好的项目遵循几个原则： +- 分离数据文件和代码文件 +- 从原始数据中分离生成的数据。 +- 有一个README.md文件帮助人们安装和使用该项目。 +- 有一个requirements.txt文件列明项目运行所需的所有包。 +- 有一个单独的settings.py 文件列明其它文件中使用的所有的设置 + - 例如，如果从多个Python脚本读取相同的文件，把它们全部import设置和从一个集中的地方获得文件名是有用的。 +- 有一个.gitignore文件，防止大的或秘密文件被提交。 +- 分解任务中每一步可以单独执行的步骤到单独的文件中。 - For example, we may have one file for reading in the data, one for creating features, and one for making predictions. + - 例如， - Stores intermediate values. For example, one script may output a file that the next script can read. + - This enables us to make changes in our data processing flow without recalculating everything. Our file structure will look something like this shortly:
