Today, we will look at another exciting combination technique in Python. Let’s start with a pure music piece~ filter() is a built-in higher-order function in Python used to filter iterable objects (such as lists, tuples, etc.). By combining it with a lambda function, we can succinctly define filtering conditions. For example, filtering even numbers: numbers … Read more

Back to top 1. What is Serverless? Serverless literally means “no server” in Chinese, but its true meaning is that developers no longer need to worry … Read more
In automotive MBD (Model-Based Design) development, the Delay Module in Simulink is an extremely fundamental yet crucial component. For example, by using the Delay Module, we can simulate physical world delays, including delays in sensors, actuators, and communications: Actual sensors (such as temperature, pressure, and position sensors) experience physical delays (mechanical response, filtering, signal processing … Read more
Anonymous Functions The lambda keyword creates anonymous functions within Python expressions. However, Python’s simple syntax restricts the body of a lambda function to pure expressions. In other words, the body of a lambda function cannot contain assignments or use statements like while and try. Anonymous functions are most suitable for use in parameter lists. For … Read more
With the background of technological advancements in electrification, intelligence, and connectivity, the electronic and electrical architectures across various industries are undergoing profound transformations. New architectures are gradually replacing traditional ones in fields such as automotive, engineering machinery, energy storage, and shipping, transitioning from traditional distributed architectures to domain-centric and even central-centric models, with controller functions … Read more
1 Understanding the Basics of Python Functions and Parameters 1.1 Basic Structure of Function Definition In Python, functions are the core tool for code reuse. A function can be defined using the <span>def</span> keyword. For example, here is a simple example: def greet(name): # Define a function that takes one parameter name print(f"Hello, {name}!") # … Read more
<span>filter()</span> is a built-in high-order function in Python used to filter sequences, removing elements that do not meet the specified conditions, and returning an iterator object (returns a list in Python 2.x and an iterator in Python 3.x). Basic Syntax filter(function, iterable) How It Works <span>filter()</span> takes each element in <span>iterable</span> as an argument to … Read more
Figure 1: Proximity computing or edge computing brings intelligence closer to devices Edge computing is a method of processing data physically close to the location where data is generated, such as in homes and remote offices. Figure 2: IoT devices typically integrate processors with certain computing capabilities Since these things and people generating data are … Read more
Type Deduction and Auto Keyword in C++: Master Unknown Types In the world of C++ programming, type safety is a very important feature. However, sometimes manually specifying types can become cumbersome and error-prone when dealing with complex expressions or function return types. At this point, the auto keyword acts like a helpful assistant, helping us … Read more
