Pathlib actual combat: fast batch rename file

Pathlib actual combat: Quick batch rename file In daily programming work, we often need to rename files in batches.Using the PATHLIB module in the Python standard library can easily achieve this goal.This article will introduce how to use the Pathlib module to quickly re -naming files to make file management more convenient and efficient. ## What is Pathlib? Pathlib is a module introduced in Python 3.4 and above versions for processing file paths on different operating systems.It provides a concise and powerful API, which is convenient for us to operate the files. With Pathlib, we can easily create, delete, move, and rename files without worrying about the differences in the operating system. The following is an example that shows how to use the Pathlib module to create a file path and access the file: python from pathlib import Path # Define file path file_path = Path('/path/to/file.txt') # Get file name file_name = file_path.name Print (f 'file name: {file_name}') # Get the file suffix name file_extension = file_path.suffix Print (F'File Vocal Name: {File_EXTENSION} ') In the above example, we use the `Path` class to create the file path, and use the` name` and `suffix` attributes to access the file name and suffix name. ## batch rename file Let's take a look at how to use the Pathlib module to achieve the function of quickly re -naming files.Suppose we have a folder that contains many files that need to be renamed.We can use Pathlib to traverse the files in the folder and rename each file. The following is an example that shows how to use the Pathlib module to re -rename files in batches: python from pathlib import Path # Define the folder path folder_path = Path('/path/to/folder') # Documents in the folder for file_path in folder_path.iterdir(): # Check whether it is a file if file_path.is_file(): # Get file name old_name = file_path.name #An rename operation as needed new_name = old_name.replace('old', 'new') # new_path = file_path.with_name(new_name) # 名 file file_path.rename(new_path) Print (f 'has renamed files: {OLD_NAME} -> {new_name}') In the above example, we first define the path of the folder.We then use the `iTerdir ()` method to traverse all the files in the folder.For each file, we check whether it is a file, not a folder.Then, we obtained the file name and renamed it as needed.Finally, we use the `rename ()" method to rename the file. Note that in the above examples, the `replace ()` method is used to replace the string. You can change it yourself according to the specific needs. ## Configuration Example In order to allow the above examples to run smoothly, you need to perform the following configuration: 1. Replace the `/path/to/file.txt` to the actual file path you want to operate. 2. Replace the `/path/to/folder` to the actual folder path you want to operate. Make sure you have the correct read and write permissions before the operation file or folder. ## Summarize Using the PATHLIB module of Python, we can easily implement the batch rename operation of files.It provides simple and powerful APIs to make file management more convenient and efficient.In use, you can further customize and expand according to your needs. I hope this article will help you understand and use Pathlib to rename the file!
