  Here are  5 practical Python scripts  covering file operations, automation, and web requests, with clear explanations and ready-to-use code: 1.  Batch Rename Files Use Case : Rename all files in a folder (add prefix/suffix/change extension). import os def batch_rename(path, prefix="", suffix="", new_ext=None): for filename in os.listdir(path): name, ext = os.path.splitext(filename) new_name = f"{prefix}{name}{suffix}{new_ext if new_ext else ext}" os.rename( os.path.join(path, filename), os.path.join(path, new_name)) # Example: Add prefix "backup_" to all .txt files batch_rename("/path/to/folder", prefix="backup_", new_ext=".txt") 2.  Download Images from URLs Use Case : Download multiple images from a list of URLs. import requests def download_images(urls, save_dir="images"): os.makedirs(save_dir, exist_ok=True) for i, url in enumerate...

  In the future, more and more libraries will use Python as the front end (improving programming efficiency) and Rust as the back end (improving performance). python Rust is replacing C as the “backend” for high-performance Python packages. What is the reason behind this? First, let’s consider motivation. Python is easy to write, but has the problem of slow execution speed. I especially can’t write data processing libraries because Python is very slow and it’s difficult to write high-performance libraries in pure Python. However, Python is the primary language for machine learning and data engineering. So when you try to write a library for data engineers or machine learning engineers, you run into the following problems: Although we need to write APIs in Python, high-performance data processing tasks cannot be done solely in Python. This means that you have the following options for writing a library: Either you learn and use C, or someone else learns C, writes a library, and you ...

 Driven by the wave of digital transformation, the development of programming languages ​​presents a new pattern. Based on the current technology development trends and market demand, this article conducts an in-depth analysis of the five most influential programming languages ​​in 2025. 1. Python Continue to lead the field of artificial intelligence and data science, and its rich machine learning libraries and data analysis tools keep it in the lead. Emerging web frameworks and automation tools have expanded its application scope. 2. JavaScript/TypeScript The dominant position in the field of front-end development is stable, and the Node.js ecosystem continues to prosper. TypeScript's type system improves the development efficiency of large projects and is expected to become more popular. 3. Go The preferred language for cloud computing and microservice architecture, its concurrency model and efficient compilation features meet the needs of modern distributed systems. The prosperi...

  Programming language theory is the subfield of computer science that studies the design, implementation, analysis, characterization, and classification of programming languages. 1. Java You might ask, “Is Java obsolete?” Of course not. Why is Java still popular? Java is one of the oldest and most robust programming languages. It is also an object-oriented language mainly used for Android application development. This is one of the main reasons it is still used today. However, with the advent of programming languages ​​like Kotlin (also suitable for Android development), Java is becoming less popular. However, Java remains one of the most expensive programming languages ​​and is in great demand. According to Indeed, software developers are interested in Java developers and pay more than $ 100,000 a year. 2. Swift Swift iOS application development is currently very popular. Swift is a very stable programming language and worth studying. It’s easier to learn than Java. YouTube has a...
