Pathlib fast entry tutorial (Pathlib Quick Start Tutorial)

Pathlib fast entry tutorial In Python, the `Pathlib` module is a standard library used to process the file system path. It provides a simple and intuitive way to operate files and directory.This tutorial will introduce the basic usage of the `Pathlib` module, and how to use it to manage files and directory. Install `Pathlib` ------ Before using the `Pathlib`, we need to ensure that your Python version is higher than 3.4.In most cases, `Pathlib` has been installed in Python by default, so it does not need to be installed. If your Python version is low or not installed `Pathlib`, you can install it by the following command: python pip install pathlib Import `Pathlib` ------ We need to import it before starting to use `Pathlib`.You can use the following code to import `Pathlib` into your Python script: python from pathlib import Path Create path object ------ In `Pathlib`, we use the` Path` class to represent the path in the file system.In order to create a path object, you can use the following code: python path = Path('example.txt') The above code will create an `Path` object with a file named` EXAMPLE.txt`.You can also use the absolute path to create path objects, such as: python path = Path('/Users/username/Documents/example.txt') Pathway ------ Once we create path objects, we can use various methods and attributes in the `Path` class to operate the path. 1. `Exist ()` Method: It is used to check whether the path exists.For example: python Print (path.exist ()) # output: true 2. `is_file ()` Method: It is used to check whether the path is a file.For example: python Print (path.is_file ()) # Output: true 3. `is_dir ()` Method: It is used to check whether the path is the directory.For example: python Print (path.is_dir ()) # Output: false 4. `name` attribute: used to obtain the file name or directory name in the path.For example: python Print (PATH.NAME) # Output: Example.txt 5. `Parent` attribute: used to obtain the parent directory in the path.For example: python Print (path.parent) # output:... File and directory operation ------ In addition to path operations, `Pathlib` also provides many methods for creating, replication, movement, and delete files and directory. 1. `Touch ()` Method: Used to create a new file.For example: python path.touch() 2. `mkdir ()` Method: Used to create a new directory.For example: python path.mkdir() 3. `rename ()` method: used to rename files or directory.For example: python path.rename('new_example.txt') 4. `unlink ()` method: used to delete a file.For example: python path.unlink() 5. `rmdir ()` Method: Used to delete an empty directory.For example: python path.rmdir() Traversal catalog ------ Using `Pathlib`, you can easily traverse the files and subdirectory in the directory.You can use the following code to traverse all the files and directory in the directory: python for item in path.iterdir(): print(item.name) The above code will traverse all the files and directory in the `Path` directory and print their names. Landscap ------ Sometimes the path may be long or complicated.`Pathlib` allows you to splicing paths by using the`/`operator to make it more readable.For example: python path = Path('/Users/username') example_path = path / 'Documents' / 'example.txt' Print (example_path) # Output: /users/username/documents/example.txt Summarize ------ This tutorial introduces the basic usage of the `Pathlib` module.You have learned how to create path objects, operate the path, perform files and directory operations, traverse directory and beautify paths.By learning `Pathlib`, you can easily process files and directory to improve the readability and maintenance of the code. I hope this tutorial can help you quickly understand and get started `Pathlib` module.I wish you success in Python development!
