Python Pathlib file and directory operation entry

Python Pathlib is a standard library of Python, which is specially used to process files and directory operations.It provides a simple and easy -to -use interface, which can help us create a series of operations such as the creation, renaming, deleting, and finding of files and directory.This article will introduce how to use Python Pathlib for files and directory operations, as well as commonly used code examples and related configurations. First of all, we need to ensure that the Python version is 3.4 or above, because Pathlib began from Python 3.4. In the Python script, we need to import the Pathlib module first: python from pathlib import Path Next, we can use the Path class to create path objects to operate files and directory.You can use the absolute path or relative path to initialize the Path object.For example, the following code example creates a path object to the current working directory: python path = Path() If you want to create a path object to a specific directory or file, you can pass the path parameters at the initialization.For example, to create a path object that points to `/Home/User/Documents`, you can write this: python path = Path('/home/user/documents') To obtain the attributes of the path object, you can use the following methods and attributes: -` Resolve () `: The absolute path of the return path. -` name`: file name or directory name of the return path. -` Parent`: The parent directory path of the return path. -` is_dir () `: Check whether the path is the directory. -` is_file () `: Check whether the path is a file. The following is an example that shows the attribute of how to obtain the path object: python path = Path('/home/user/documents') print(path.resolve()) # 输出: /home/user/documents Print (path.name) # Output: Documents Print (path.parent) # Output: /Home /User Print (path.is_dir ()) # Output: true Print (path.is_file ()) # Output: false Next, we will introduce some commonly used files and directory operations. 1. Create a directory: Use the `mkdir ()` method to create a new directory.For example, the following code example creates a directory called "New_directory": python path = Path('/home/user') new_directory = path / 'new_directory' new_directory.mkdir() 2. Create files: Use the `Touch ()` method to create a new file.For example, the following code example creates a file called "New_file.txt": python path = Path('/home/user/documents') new_file = path / 'new_file.txt' new_file.touch() 3. Traversing catalog: Using the `iTerdir ()" method can traverse all the files and subdirectors in the directory.For example, the following code example traverses all the files and directory in the current directory, and printed their names: python path = Path() for item in path.iterdir(): print(item.name) 4. Find file: Use the `Glob ()` method to find the matching file according to the form mode.For example, the following code example finds all files ending in the current directory with ".txt": python path = Path() txt_files = path.glob('*.txt') for file in txt_files: print(file.name) Through the above examples, we can use the Python Pathlib module to easily perform files and directory operations.At the same time, more complex functions can be achieved according to specific needs in accordance with other Python standard libraries or third -party libraries. Summary: This article introduces the basic usage and common operations of the Python Pathlib module, covering the creation of path objects, attribute acquisition, and the creation, traversing and search of files and directory.Hope to help you better use Python for files and directory operations.
