Practical tips for Python scripting in Linux
Practical tips for Python scripting in Linux, specific code examples are required
Introduction:
Python is a programming language that can be widely used in various fields , and Linux, as a free and open source operating system, is widely used in servers, embedded devices and other fields. In the Linux environment, Python scripts can exert powerful power to help us complete various tasks. This article will introduce some practical tips for using Python scripts in Linux and provide specific code examples.
1. Combining Shell Commands with Python
In Linux, we often need to use Shell commands to perform some system-level operations. Python provides the os
module and the subprocess
module, which can easily call Shell commands. Here are some common examples:
1. Execute a Shell command and get the output:
import subprocess result = subprocess.check_output("ls -l", shell=True) print(result.decode())
2. Execute multiple Shell commands:
import subprocess commands = [ "sudo apt update", "sudo apt upgrade -y", "sudo apt install python3-pip -y", ] for cmd in commands: subprocess.call(cmd, shell=True)
3. Restart via Shell command Directed output:
import subprocess with open("output.txt", "w") as f: subprocess.call("ls -l", shell=True, stdout=f)
2. File and directory operations
File and directory operations in Linux systems are frequently encountered tasks. Python provides the os.path
module and ## The #shutil module is used to process files and directories.
import os os.makedirs("my_directory")
import shutil shutil.rmtree("my_directory")
import os for root, dirs, files in os.walk("my_directory"): for file in files: print(os.path.join(root, file))
Network operations in the Linux environment are very common. Python provides the
socket module and the
requests module to handle network requests.
import requests response = requests.get("https://www.example.com") print(response.text)
import http.server handler = http.server.SimpleHTTPRequestHandler httpd = http.server.HTTPServer(("", 8000), handler) httpd.serve_forever()
import smtplib from email.message import EmailMessage msg = EmailMessage() msg.set_content("Hello, World!") msg["Subject"] = "This is a test email" msg["From"] = "sender@example.com" msg["To"] = "recipient@example.com" with smtplib.SMTP("smtp.example.com") as server: server.send_message(msg)
This article introduces some practical skills for using Python scripts in Linux, including combination with Shell commands, file and directory operations, and network operations. Through these tips, we can better utilize the power of Python to complete various tasks. The above sample code is only a demonstration and readers can modify and expand it according to their actual needs.
