How does Python's unittest or pytest framework facilitate automated testing?
Jun 19, 2025 am 01:10 AM
Python's unittest and pytest are two widely used testing frameworks that simplify the writing, organizing and running of automated tests. 1. Both support automatic discovery of test cases and provide a clear test structure: unittest defines tests by inheriting the TestCase class and starting with test\_; pytest is more concise, just need a function starting with test\_. 2. They all have built-in assertion support: unittest provides assertEqual, assertTrue and other methods, while pytest uses an enhanced assert statement to automatically display the failure details. 3. All have mechanisms for handling test preparation and cleaning: un

What are dynamic programming techniques, and how do I use them in Python?
Jun 20, 2025 am 12:57 AM
Dynamic programming (DP) optimizes the solution process by breaking down complex problems into simpler subproblems and storing their results to avoid repeated calculations. There are two main methods: 1. Top-down (memorization): recursively decompose the problem and use cache to store intermediate results; 2. Bottom-up (table): Iteratively build solutions from the basic situation. Suitable for scenarios where maximum/minimum values, optimal solutions or overlapping subproblems are required, such as Fibonacci sequences, backpacking problems, etc. In Python, it can be implemented through decorators or arrays, and attention should be paid to identifying recursive relationships, defining the benchmark situation, and optimizing the complexity of space.
How can you implement custom iterators in Python using __iter__ and __next__?
Jun 19, 2025 am 01:12 AM
To implement a custom iterator, you need to define the __iter__ and __next__ methods in the class. ① The __iter__ method returns the iterator object itself, usually self, to be compatible with iterative environments such as for loops; ② The __next__ method controls the value of each iteration, returns the next element in the sequence, and when there are no more items, StopIteration exception should be thrown; ③ The status must be tracked correctly and the termination conditions must be set to avoid infinite loops; ④ Complex logic such as file line filtering, and pay attention to resource cleaning and memory management; ⑤ For simple logic, you can consider using the generator function yield instead, but you need to choose a suitable method based on the specific scenario.

How do I perform network programming in Python using sockets?
Jun 20, 2025 am 12:56 AM
Python's socket module is the basis of network programming, providing low-level network communication functions, suitable for building client and server applications. To set up a basic TCP server, you need to use socket.socket() to create objects, bind addresses and ports, call .listen() to listen for connections, and accept client connections through .accept(). To build a TCP client, you need to create a socket object and call .connect() to connect to the server, then use .sendall() to send data and .recv() to receive responses. To handle multiple clients, you can use 1. Threads: start a new thread every time you connect; 2. Asynchronous I/O: For example, the asyncio library can achieve non-blocking communication.

Polymorphism in python classes
Jul 05, 2025 am 02:58 AM
Polymorphism is a core concept in Python object-oriented programming, referring to "one interface, multiple implementations", allowing for unified processing of different types of objects. 1. Polymorphism is implemented through method rewriting. Subclasses can redefine parent class methods. For example, the spoke() method of Animal class has different implementations in Dog and Cat subclasses. 2. The practical uses of polymorphism include simplifying the code structure and enhancing scalability, such as calling the draw() method uniformly in the graphical drawing program, or handling the common behavior of different characters in game development. 3. Python implementation polymorphism needs to satisfy: the parent class defines a method, and the child class overrides the method, but does not require inheritance of the same parent class. As long as the object implements the same method, this is called the "duck type". 4. Things to note include the maintenance
How do I slice a list in Python?
Jun 20, 2025 am 12:51 AM
The core answer to Python list slicing is to master the [start:end:step] syntax and understand its behavior. 1. The basic format of list slicing is list[start:end:step], where start is the starting index (included), end is the end index (not included), and step is the step size; 2. Omit start by default start from 0, omit end by default to the end, omit step by default to 1; 3. Use my_list[:n] to get the first n items, and use my_list[-n:] to get the last n items; 4. Use step to skip elements, such as my_list[::2] to get even digits, and negative step values ??can invert the list; 5. Common misunderstandings include the end index not
