consider naming them with double leading underscores and no trailing underscores. This invokes Python’s name mangling algorithm, where the name of the class is mangled into the attribute name. This helps avoid attribute name collisions should subclasses inadvertently contain ...
Python mangles these names with the class name: if class Foo has an attribute named a , it cannot be accessed by Foo.a . (An insistent user could still gain access by calling Foo._Foo__a .) Generally, double leading underscores should be used only to avoid name conflicts with attribute...

需要注意的是,如果输入的参数如果带有 “.”,采用__import__直接导入 module 容易造成意想不到的结果。 OpenStack 的oslo.utils封装了__import__,支持动态导入 class, object 等。 命名规范 Python 中的naming convention 以及 coding standard 有很多好的实践,例如Google 的Python 编程规范等。 就命名规范而言, ...
The context object is a Python class that's defined in theLambda runtime interface client. To return the value of any of the context object properties, use the corresponding method on the context object. For example, the following code snippet assigns the value of theaws_request_idproperty (...
Naming Conventions: Check if module names use lowercase letters and underscores (snake_case). For example, my_module.py Verify if class names use CapWords (also known as CamelCase) convention, where the first letter of each word is capitalized without underscores. For example, MyClass ...
