Package and Module Names Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged. Since module names are mapped to file names...
特别地,import 可以被动态的从任何地方调用。 使用Python 包(package)组织代码 稍微正式一点的项目,都会通过将代码组织成有层次结构的组织,以便于管理和持续维护。Python 通过包(package)的方式来组织代码,包是一种特殊的模块(module)。 Python 的包有两种形式,分别是Regular packages 和 namespace packages。 所谓 Re...
package 包名,只限于逻辑上的管理,同一个包名下的查询或者函数可以直接调用 import 用于导入类或者静态方法 global 全局变量 function 自定义函数 query 查询 rule end 规则体 规则体语法结构 规则体是规则文件内容中的重要组成部分,是进行业务规则判断、处理业务结果的部分。 rule "ruleName" attributes when LHS the...
