  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 ...

  Engineers have to do a huge amount of coding. It’s really tough having to handle other duties and schedule management at the same time. Having the right tools is key to being a successful engineer.
