Python Pathlib Getting Started Guide
The Python Pathlib module is part of the Python 3.4 and above versions, which provides a simple and object -oriented method for processing file paths.It can help developers handle the operation of files and directory easier, and avoid errors often occur when using traditional string paths.
In this article, we will introduce how to use the Python Pathlib module and some of its basic functions.
1. Import pathlib module
First, we need to import the Pathlib module.In Python 3.4 and above versions, it is built -in, so we don't need to install extra packages.
python
from pathlib import Path
2. Create path object
The main purpose of using the Pathlib module is to create path objects. These objects can be directly used in files and directory operations.
-The creation path object can use the current working directory as the starting point:
python
current_directory = Path.cwd()
-Coloning path objects can directly specify the string of the path:
python
file_path = Path("path/to/file.txt")
-The creation path object can connect multiple path segments:
python
file_path = Path("path") / "to" / "file.txt"
3. Check whether the path exists
Use the `Exist ()` method to check whether the path exists:
python
file_path = Path("path/to/file.txt")
if file_path.exists():
print("File exists!")
4. Create a directory
Use the `mkdir () method to create a directory:
python
directory_path = Path("path/to/new_directory")
directory_path.mkdir()
5. Create files
Use the `Touch ()` method to create a file:
python
file_path = Path("path/to/new_file.txt")
file_path.touch()
6. Traversing directory
Use the `iTerdir ()` method to traverse the files and subditors in the directory:
python
directory_path = Path("path/to/directory")
for item in directory_path.iterdir():
print(item.name)
7. Read the content of the file
Use the `Open ()` method to open the file and read its content:
python
file_path = Path("path/to/file.txt")
with file_path.open() as f:
content = f.read()
print(content)
8. Delete files or directory
Use the `unlink ()` method to delete files, and use the `rmdir () method to delete the empty directory:
python
file_path = Path("path/to/file.txt")
file_path.unlink()
directory_path = Path("path/to/directory")
directory_path.rmdir()
9. File copy
Use the `copy ()` method to copy the file:
python
src_file_path = Path("path/to/source_file.txt")
dest_file_path = Path("path/to/destination_file.txt")
src_file_path.copy(dest_file_path)
The above is some basic functions of the Python Pathlib module.We can see that using this module can handle files and directory operations more conveniently without manually building road string or processing various boundaries.
I hope this guide can help you better understand and use the Python Pathlib module.If necessary, you can check the [official document] (https://docs.python.org/3/library/pathlib.html) to get more detailed information.
