To achieve our goal, we’ll use theindexmethod which is a function associated with a specific class and serves for a certain function when attached to a variable following a dot. Theindexmethod in particular, returns the index of the given substring, inside the string.The substring that we ...
Similarly, you can find the available methods for a widget object using the standard dir() function. If you try it, you'll see there are over 200 common widget methods, so again identifying those specific to a widget class is helpful. print(dir(btn)) print(set(dir(btn)) - set(dir(...

You access it with an instance or object of the class. A function doesn’t have this restriction: it just refers to a standalone function. This means that all methods are functions, but not all functions are methods. Consider this example, where you first define a function plus() and ...

本文用python来解释hook的实现方式,并展示在开源项目中hook的应用案例。hook函数和我们常听到另外一个名称:回调函数(callback function)功能是类似的,可以按照同种模式来理解。 2. hook实现例子 据我所知,hook函数最常使用在某种流程处理当中。这个流程往往有很多步...
Lambda passes the context object to your function automatically when it's invoked. You can use the context object to output information about your function's invocation for monitoring purposes. The context object is a Python class that's defined in the Lambda runtime interface client. To return...
